Village is about 1300m long, and the railway bridge from Qianfeng Village to Qianfeng Village is about 259m, and the new flood control embankment project of Luxi River is 2575.76m. A new landscape project with a width of 20-25m on both sides of the river section, with a total area of about 71,500 m2. The planned investment scale of the above two projects is about 133,223,100 yuan. The construction sites are located within the scope of Qianfeng District. The construction unit is Guang'an Xinhong Investment Holdings Co., Ltd.

In accordance with the " Environmental Protection Law of the People's Republic of China" (January 1, 2015), the Environmental Impact Assessment Law of the People's Republic of China (September 1, 2016) and the Regulations on Environmental Protection Management of Construction Projects (Order No. 682)) requirements, the project requires an environmental impact assessment. Based on "construction project environmental impact assessment of Classification Catalog" (Department Order No. 44, revised 2018) dividedthe project XIEJIAWAN park project is "Forty, social programs and services -119-- parks (including zoos, Botanical Garden, Theme Park)- Others; The comprehensive improvement project of Luxi River is “46, Water Conservancy- 145 - River Lake Renovation-Other”. According to the requirements, the above two sub-projects should prepare an environmental impact report form. To this end, the construction unit entrusted our company to undertake the preparation of the environmental impact report form of the project. The evaluation will analyze and evaluate the environmental impact of the project construction based on engineering analysis and project characteristics, and propose measures and recommendations to prevent and mitigate adverse impacts. At the same time, through the environmental impact assessment of the project, it provides a scientific basis for the environmental protection administrative department's environmental decision-making, environmental supervision and project environmental management. 1. 2 Necessity of engineering construction 1. 2.1 Necessity of Xiejiawan Park Project Construction (1) Urban park construction can improve the quality of the urban environment and beautify the environment. To improve the city's appearance, the primary task of urban park greening is to improve the ecological environment. With the development of industry, a large amount of harmful gases are released into the atmosphere, which seriously pollutes the air. Green plants can absorb harmful gases, purify the air, reduce noise, regulate urban temperatures, and improve the living environment. Because urban greening is the embodiment of material civilization and a symbol of urban spiritual civilization. The park's greening layout is reasonable, the facilities are complete, the building is exquisite, the management is perfect, the operation is orderly, and the greenery is everywhere, the flowers are bright, the four seasons are green. The significance of the construction of modern urban parks means the significance of the construction of modern urban parks. Living in a city with beautiful scenery and harmonious ecological environment, people's mind and body will be healthier, more energetic, and more creative. It will promote social civilization and economic prosperity, making the city a place that people yearn for.

(2) Qianghai District Xiejiawan Park and Huaying Mountain Range are across the city and have good mountain landscape resources. Surrounded by simple and natural towns and villages, the transportation is convenient and the environment is beautiful. New striker accelerate the development of cultural tourism industry, the construction of ecological demonstration city sponge district, according to "city, culture, tourism, industry interaction communion" development ideas, to build

striker surrounding renowned tourist and leisure destination.

1. 2.2 Necessity of the comprehensive renovation project of Luxi River The Qianfeng Logistics Park is located in the northwest of Huaying Mountain in the eastern part of the Sichuan Basin. There is no perfect flood control system in the riversection of this project. The river bends narrowly, the silt is seriously silted, the slope is gentle, the water is not smooth, and there is a rainstorm along the banks of the river. Ten thousand mu of farmland is vast and inundated for up to 2 to 3 days, causing serious losses to local industrial and agricultural production and people's lives and property. Every time the flood comes, the local government must invest a lot of manpower and material resources to prevent floods and floods. Flood disasters have become an important factor restricting local social and economic development.

Because the Luxi River is located in the center of the Huayu Mountain rainstorm area, the entire river course is almost at the foot of the northwestern wing of Huaying Mountain. Therefore, the Luxi River has a rapid flood collection, a large flood peak flow, a large flood water level increase, and a The rivers and farmland have many flooding times, large areas, and severe flood damage. According to incomplete statistics from the relevant departments of the Qianfeng District, the Luxi River floods along the river in the nearly 40 years from the 1970s to 2008. There have been more than 25 major floods on both sides of the strait, resulting in economic losses of tens of millions of yuan, causing great loss of life and property to the local people. Therefore, the flood became the number one natural disaster that the local people called the Hongmo, which seriously hindered the local social and economic development. The flood disaster has obviously restricted the rapid economic development of Guang'an City, and the severe flood control problem has attracted the attention of local party and government leaders.

In order to improve the flood control capacity of the front section of the Luxi River, reduce the impact of flood disasters on the farms and farmland on both sides of the river, alleviate the hazards of floods, ensure the construction of new towns in the Qianfeng District, ensure the construction of industrial concentration areas, and ensure the Luxi in the Qianfeng District. The ecological flow of the river, ensuring the leisure and entertainment environment of the new towns in the Qianfeng District, improving the overall overall image of the Qianfeng District, and comprehensively rectifying the front section of the Luxi River as soon as possible are very urgent and necessary.

1.3 Industrial policy and related planning conformity analysis 1.3.1 Analysis of compliance with industrial policies The project involves park construction and river channel comprehensive improvement project, in which the river comprehensive improvement project belongs to the flood control and decontamination facility management (N7610).

The original pollution situation and major environmental problems related to this project : (1) The main environmental problems in the Luxi River Luxi River originates in the northwest wing of Huaying Gui Tai Wo Hing town caoba field of Guang'an Tong, in Guang'an protect security zone in the town of Dragon Bridge Department will import Qujiang River, the river a total length of 49.0km, drainage area 192km2, the average slope of the river is

23

14.9 ‰. Location: East longitude 106°40′～106°57′, north latitude 30°25′～30°40′. The current status of the Luxi River remediation project is mainly farmland, woodland, grassland, etc. It does not involve basic farmland. There are a small number of residential areas on both sides of the river in the project section. There are residential sewage, domestic garbage, farmland fertilizer and pesticide loss on both sides of the project river. The river channel has a certain pollution impact on the water quality of the Luxi River.

The current situation of the Luxi River Logistics Park section The striker Luxi River River Logistics Park section of the current river bend narrow, river slope mostly bare soil, slope instability shore, more serious landslides, flood safety risks exist, scattered along the banks piled a lot of garbage, especially There are many construction wastes piled up near the railway, which seriously affects the surrounding landscape environment. The left bank has residents distributed, and its domestic sewage is not included in the municipal pipe network, and it enters the Luxi River directly, causing certain pollution to the river channel; Status river segment and logistics park planning body are consistent, straighter; to make close to the overall effectiveness of the World Bank loan Luxi River downstream of the landscape renovation project being implemented in full, before the Luxi River front arealogistics park area segment Landscape engineering is also imminent. (2) There are major environmental problems in Xiejiawan Park At present, the proposed site of Xiejiawan Park is in the wasteland, the surrounding municipal roads have been completed, and the original houses and other structures on the ground have been removed and cleaned up. According to the “Xiejiawan Reservoir Safety Appraisal Report” submitted by the construction unit (July 2018), the report concluded that the Xiejiawan Reservoir belongs to the second- class disease dam in terms of safety status, although the project management has been institutionalized and the overall safety operation Good, but the dam in addition to rainfall inspection, lack of water conditions report and dam observation facilities, and downstream road box culvert drainage is not smooth, resulting in long-term accumulation of water downstream of the dam, soaking the dam dam foundation, the dam operation is unfavorable, it is recommended to take Targeted rectification measures. Therefore, this evaluation proposes the following prevention measures for the Xiejiawan Reservoir: 1 Add observation facilities, communication equipment, and improve management facilities. 2 Renovate the road culvert so that the downstream water can be discharged to ensure the stability and safety of the dam.

The natural environment and social environment of the locality Table (4) Natural environment profile (terrain, landform, geology, climate, meteorology, hydrology, vegetation, biodiversity, etc.) : 3.1 Overview of the natural environment 3.1.1 Geographic location Forward area under the Guang'an City, 2013 Established in August, it is located on the east bank of the Qujiang River in Guang'an, Sichuan Province, in the middle of the Huaying Mountain Range, on the east bank of the Yangtze River tributary, the Guang'an District in the west and north, Huayan City and Linshui County in the south, and Dazhu County in the east. It is located between 30°26′15.02′′~30°39′8.05′′ north latitude and between106°38′36.14′′~106°59′14.30′′ east longitude. The Qianfeng District is located in the heart of the Chengdu-Chongqing Economic Zone, and the core of the Sichuan-Chongqing Cooperation Demonstration Zone. The project is located in Qianfeng District of Guang'an City. The site of the comprehensive treatment project of Luxihe Logistics Park is located in the center of the Qianfeng Center and the Luxi River section of Binhe North Road in Qianfeng District. The construction project of Xiejiawan Park inQianfeng District is located in the vicinity of Xiejiawan Reservoir inQianfeng District, southeast of Liangshuijing Reservoir. The location of the project is shown in Figure 1. 3. 1. 2 Geological overview (1) Topography The project area is located in the center of the hinterland of the Sichuan Basin. The terrain in the area is dominated by hills with an altitude of less than 500m. The high hills with an elevation of more than 350moccupy a slight position. In addition, there are a small number of different river terraces along the banks of the river. From the geological structure background, the project area is in the middle of the Yangtze River fold belt with weak and wide folds. Therefore, regardless of the high hills, low hills and terraces, the general pattern and the fine vein direction are generally not controlled by the structural traces, and the main factors affecting the elevation and its combined shape are the lithology and water system shape scale and weathering. The role of denudation is mainly due to the type of erosion and low hills. The stacked terraces along the river bank in the planning area are of the type of erosion accumulation. The terrain of the project area is low in the north, high in the west and low in the west.The slope of the Luxi River in the project area is small, and the average river channel ratio is reduced by 1‰. Luxi River in a northeast - southwest flow, the river twists and turns, the total gradient of about 1 ‰, river width7 ~ 12m, depth of about 0.5 ~ 2m. The landforms in the project area are mainly tectonic erosion landforms and erosion accumulation landform units. The tectonic erosion features are mainly hilly landforms, controlled by lithology and structure. The hillforms are mostly characterized by flat tops, towers, irregular strip-shaped ridges and other geomorphological landscapes. Heap erosionlandform product mainly along the banks of asymmetrical development of floodplain terraces and landscape, based on regional geological data and

26

engineering geological mapping survey, a common terrace distribution.There is a gravel pebble layer or a sandy loam layer on the bank of theLuxi River bed and the open river core. The thickness is 0~10m, which is often damaged and incompletely preserved. The terrain of the project Xiejiawan Park is dominated by reservoirs, mountain rocks and valleys. The overall terrain gradually rises from west to east, and the altitude in the region is maintained at 330-430 m. The commanding height creates favorable conditions for overlooking the whole park and overlooking the scenery. It also contributes to the beautiful natural landscape resources of the park. Xiejiawan Park The hydrophilic landscape combines rolling hills and jungles to create a variety of landscapes and layers. The slope of Xiejiawan is relatively slow. There are cliffs and cliffs in some areas. The slope direction is mainly east, southeast and west and southwest. (2) Regional geological structures and earthquakes The project area belongs to the eastern edge of the Sichuan belt in the Sichuan Settlement Belt. It is located in the northeastern part of the semi-annular structure of the Longquan Temple in the torsion tectonic system. The east and west sides are the Longuansi ancient building field and the Guansheng anticline, and the east is adjacent to China. The Lushan fold belt and the Guang'an anticline in the north. The geological structure within the project is very simple and has no large fault structure. The general trend is extended in the north-east direction, and the shape is characterized by the abrupt change of the axis curve, and the structural shape is mainly composed of gentle folds. Wings very asymmetric, North West Wing angle 1 ~ 3 °, southeast limb near the axis of about 20 °, the formation dip project area around 20 °. In the current period, the recent crustal movement is dominated by intermittent uplift, which is a weak active fault zone in the Sichuan Basin. The fault activity and seismic activity are weak. The historical earthquake frequency in the area is low, the intensity is small, and there is no seismogenic fault. The seismic effect is the epidemic area of seismic activity around the project area. According to the "China Earthquake Parameter Zoning Map" (GB18306-2001), the peak ground motion acceleration value of this area is 0.05g, the corresponding seismic basic intensity is VIdegree, and the site characteristic period Tg=0.35s. The regional structure is stable. (3) Formation lithology The strata in the project area are simple to expose, and only the Quaternary and Jurassic Zhongshang Shangshaximiao Formation (J 2S) stratum. The Quaternary coverings mainly include the Holocene residual slope, alluvial river alluvial, and alluvial deposits. The alluvial deposits are mainly distributed in riverbeds, river beaches and gentle slopes on both banks. The specific details are as follows: 1 Jurassic Zhongshang Shangshaxi Temple Group (J 2 S) : Shangshaximiao Formation (J 2S) : The bottom is gray, gray-green thick layered calcareous fine sandstone (thickness15~20m), and a set of purple-red silty mudstone. The lithology is weak, and it is resistant to weathering and erosion. 2 Quaternary (Q) New system (Q 4 al) : 1) Modern river accumulation (Q 4 al) : The earlier ones are light gray yellow and yellowish brown silty

27

clay; they are distributed in the terraces of grades I and II. 2) Modern river accumulation (Q 4 3al) : The main sedimentary fine sand, sand or silt in the floodplain. 3) Residual slope accumulation layer (Q 4 dl+el) : purple brown, brown yellow loam or sand, with a small amount of rock fragments, distribution and slope or slope angle, thickness generally 0.5~6.0m, local thickness up to 6.0 ~11.5m. 4) Collapsed accumulation layer (Q 4 dl+col): consists of block gravel-cracked soil, mainly distributed at steep slope angles, with a thickness of 0~6m. 5) Artificial accumulation layer (Q 4 r): consists of mortar stone, concrete, construction and domestic garbage, scattered in the slope of the bank slope, thickness 0~8m. (4) Hydrogeological conditions According to the geotechnical structure and aquifer properties of the project area, groundwater can be divided into two types: Quaternary loose accumulation pore water and bedrock fissure water. 1 Quaternary loose layer pore water It is generally buried in riverbeds, terraced alluvial deposits, and bank slopes and sediment layers on both banks of the river valley. In addition to relying on atmospheric precipitation, the groundwater in the loose accumulation layer of the riverbed is also replenished by the upstream river water and the bedrock fissure water. It is near recharge and is discharged nearby. The runoff route is shorter, the drainage is better, and the water content is more abundant. The groundwater in the terraced alluvial and riverbank slopes and the groundwater in the loose accumulation layer are mainly replenished by atmospheric precipitation recharge or bank slope fissure water, and then replenished. Since the cover layer is thin and does not have a storage condition, the water content is poor. 2 bedrock fissure water The stratum structure of the project area is mainly characterized by silty mudstone. The silty mudstone has a slightly better water-blocking property, and the rock layer is gently inclined, the fissure is not developed, the recharge conditions are poor, and the river bank is empty and the drainage conditions are good, so the groundwater is not easy to exist. The bedrock fissure water is mainly recharged by atmospheric precipitation, and is recently drained in the river ditch. In some areas, groundwater can be observed to be exposed to the surface in the form of descending springs. The flow of these springs is very small (< 0.5L/s), and with the seasons. Variety. The groundwater is mainly Quaternary pore diving, followed by bedrock fissure water, which is mainly replenished by the Luxi River water, followed by atmospheric rainfall recharge, and is discharged to the river bed. According to the information provided by the construction unit, the water sample of Luxi River is heavy calcium carbonate water.

Seen from the above table statistics, monitoring sections XIEJIAWAN reservoir BOD 5, COD exceeded the standard, the downstream river monitoring sections Luxi, COD exceeded the standard, other indexes satisfies "Surface Water Environment Quality Standard" (GB3838 Class III waters standard in -2002). XieBay Reservoir exceeded the main reason is its perimeter has been completed and a certain residential area, but the corresponding supporting sewer network failed to put into use, some sewage ditches along the bus into the reservoir due to rain, with the municipal pipe The water quality will be improved and the

39

water quality will be improved. The main reason for the over-standard section of the lower reaches of the Luxi River is that there are residents in the lower reaches of the rectification section. The domestic sewage is not included in the municipal pipe network and goes straight into the Luxi River due to the area. Residents have been included in the relocation plan. After the residents are relocated, the domestic sewage will be discharged into the Luxi River and the water quality will be improved.

The sewage discharge (including construction period and operation period) generated by the project will not enter the Xiejiawan Reservoir and the Luxi River, and will not aggravate the water pollution of the Xiejiawan Reservoir and the Luxi River. 4. 3 sound environment quality status evaluation The acoustic environment quality standard (GB3096-2008) of the Luxi River and Xiejiawan Reservoir area involved in thisproject is classified into two types of acoustic environment functional zones.

Engineering Analysis Table (6) 6.1 Process

6.1.1 XIEJIAWAN park construction

The proposed project XIEJIAWAN park construction period of service processes is shown in

Figure 6.1 --1.

Figure 6.1 --1 XIEJIAWAN park building construction, service and production processes

of pollution map link

The project XIEJIAWAN park construction throughout the construction process of construction along

the terrain, without blasting process, with a total construction period is 10months, construction

workers, mainly local residents, construction management house set in the middle of the venue.

The construction period of the project Xiejiawan Park mainly includes the renovation of the facilities

of the park, the finishing of the terrain of some of the park bases, the planting of vegetation and the

construction of the landscape. Firstly, the general topography and topography are mechanically

arranged, and then artificially trimmed, and the corresponding pipelines such as water supply and

47

drainage and power supply are excavated and laid, and then the road is constructed and laid according to the design. Finally, the plant is planted according to the plant plan, and the corresponding plant is installed. facility. Most of the project main construction relies on the natural topography and landform within the project. The land area to be leveled is less, and the construction difficulty is small. Construction is carried out in accordance with the general small-scale shared building construction method, and the construction period is short.

The construction process of the Xiejiawan Park of this project does not involve reservoir water body engineering, and does not carry out operations such as dredging and cofferdam, and retains the shape of the original reservoir water after the completion of construction. No new restaurants and accommodation facilities in Xiejiawan Park (if you need to set up a meal, you need to prepare an environmental impact assessment separately)

6.1.2 Luxi River River Restoration

Due to the particularity of the project, the construction period was selected during the dry season. The order of construction is from the outside to the inside, the filling of the embankment is from bottom to top, and the coastal line is gradually carried out. After preliminary analysis, the specific key lines of the project are as follows:

Construction unit entry→→ Construction road construction→→ River dredging →→Construction diversion (woven bag cofferdam) →→ Foundation pit excavation (filling)→→Concrete retaining wall pouring→→ Earthwork filling→→ Slope protection → → step construction → → the project is completed.

(1) The process flow and pollution production during the construction period are as follows:

6.1-2 Process flow and pollution location map of the Luxi River channel treatment project during construction period

(2) Description of construction process

1 river bed dredging

During the construction process, dry dredging method is used to clear the silt method, that is, after the construction diversion, the river construction surface is air- dried for several days, excavated with a backhoe excavator to reduce water carrying operations, and then loaded and transported to the river remediation landscape area. Abandoned silt area. The river dredging and dredging requirements are carried out in the dry season. Due to the whole line construction, the river channel needs full line diversion. When multi-point construction, the cofferdam height between the construction faces should not flood the upstream river bank during flooding. When the construction conditions are met, the upper slope of the river course is cleared according to the prototype to facilitate the construction machinery operation and the construction of the lower river layer, and then the earthwork and sludge are excavated by using the backhoe. The cleared silt is not placed on the shore and transported directly from the closed tanker to the abandoned silt area of the river course.

49

② earthwork excavation

Excavation slag using 1.6m ³ excavator, bulldozer 88KW aggregate slag heap, 15T dump trucks, earth-moving excavation process using the first material was used directly in cofferdam filling, transport distance 0.5 ~ 1km. The remaining part is piled up in the temporary stockyard behind the embankment, and is used as part of the backfilling of green planting soil with a transport distance of 0.5km.

Provide information on the construction of the park during the excavation amount less stonework, stonework excavated mainly pneumatic drill to drill, and auxiliary artificialstonework hit hard protective layer according to the project involves the excavation site conditions and construction unit, No explosive blasting operations are used. Using 1.6m ³15t excavator loading dump trucks. This main project of earth excavation is about 30,000 m 3 (the natural way).

3 dike works

The construction sequence is from the outside to the inside, and the embankment is filled from bottom to top and gradually along the embankment. The construction procedures of the revetment project are: foundation excavation (rolling and compacting)→ concrete retaining of retaining wall→ layered roller compaction of embankment earthwork construction→ slope protection construction→ embankment construction, and concrete stepping in the construction Construction of flood discharge culverts, etc.

The roller compacted materials of the embankment were transported from the 15t dump truck to the working surface filling area, and then paved with 88KW bulldozer. The filling is carried out by the

“occupation method”, that is, the transportation vehicle is gradually discharged forward on the newly filled loose material, and is leveled at any time by the bulldozer, and the stone should be separated as much as possible during the paving process of the discharging. When laying the material, the thickness of the layer should be controlled, and it should be laid flat and spread to the design thickness. The work of the dike surface is carried out according to the paving, rolling and quality inspection.

The gravel cushion is paved with a 88 kW bulldozer after the 5t dump truck is used to transport the crushed stone with good particle size to the working surface filling area.The 2.8KW frog type smashing machine is layered and compacted.

1) Masonry construction

The stone masonry of this project includes the blocks of stone blocks, the step ladder, the outlet block

50

of the stilling pool and so on. The foot of the town and the outlet of the stilling pool should be crushed before the masonry, and the 13-14t vibratory roller compaction has no obvious settlement.

The stone materials are purchased from the off-site, and are transported to the construction sites of each work area by 10t dump trucks. The cranes are manually transported and installed. The mortar is mixed with a 0.25m 3 mortar mixer, and the rubber wheel is manually driven by 50 to 100m to the masonry point. Artificial joints and plastering.

The block stone masonry is constructed by the sitting method. Before the layering is built, the soil and oil on the stone should be washed out at the masonry, and the surface of the stone should be kept moist during the building. The thickness of the paving is 3 ~ 5cm. With the paving with the masonry, the joints need to be filled with mortar. The stones are strictly forbidden. The mortar in the joints should be densely packed with flat iron. During the masonry construction process, it is strictly forbidden to pile stones and then grout with mortar.

2) Concrete construction

The concrete aggregate is purchased and transported to a concrete mixing plant by a 10t dump truck, and a 0.8m 3 mixer is used to mix the concrete, and then the 10t dump truck or3.0m 3 tanker is used to transport the chute and the slide directly into the warehouse. The concrete on the retaining wall is lifted into the warehouse with a 3.0m 3 tanker transport derrick (or car crane).

Before the concrete is poured, the artificial erecting formwork (combined steel die) is used. The manual closing is used in the pouring process, the inserted vibrator iscompacted, and the temperature control measures of the concrete are required to be timely maintained to prevent concrete cracking. Penetration cracks appear.

4 earth and stone backfill

This filling must ensure that the earthwork filling mass, filling material into levee revetment using excavated material mining and quarry material in two parts, using excavated material loaded using 1.6m³ excavator, dump truck transport 15T 0.5 ~ 1km to the filling point for unloading. The material mining material is transported by a 1.6m 3 excavator and excavated with a 15t dump truck to the filling point for unloading. The crushing is carried out by bulldozer flat material, artificial watering, and 16t vibration rolling. The gravel material with small auxiliary particle size is used at the slope of the slope protection. The width of the ultra-wide filling is not less than 0.3m.

51

After the slope is cut, the layer material is laid, and the 8t slope vibration mill is used for rolling, the thickness of the paving and the number of rolling passes are used. The parameters shall be subjected to a rolling test before the start of filling.

5 slope protection construction

From the top of the foot of the town to the top of the embankment, prefabricated C20 hollow hexagonal block grass planting grass is used to protect the slope. The grass brick is a 100mm thick hollow hexagonal block. The specific structural dimensions are shown in the detailed drawing. 300mm thick humus soil is planted under the grass, and the turf is planted. The GL-1-

1.5mm polyethylene geomembrane is laid under the humus soil for anti-seepage. From top to bottom, it is turf slope protection → hollow hexagonal block grass brick thickness 100mm → humus soil thickness 300mm → GL-1 polyethylene geomembrane thickness 1.5mm. Seeds, fertilizers, wood fibers, and anti-allergic agents are added by artificial sowing method, and then artificially spread. Plants planted on slopes are often selected as extensive plants that do not require trimming and fertilization management to reduce maintenance.

6 road railing project

In order to prevent the falling river from setting safety railings on the top of the embankment and the horse's road, the railing is 1.2m high, and the railing type is railing or selected by the owner.

Factors 6.2 Project construction and operation of environmental analysis

After the completion of the project, the river surface will be completely new. The sewage interception treatment, flood discharge and internal flooding problems will be solved. The environmental impact of this project is positive and long-lasting. The adverse impacts of the project on the environment are mainly generated during the construction period, such as dust, construction noise, construction waste, etc. These effects are non-permanent and disappear as the project is completed.

Factors 6.2.1 construction of environmental analysis

(1) Analysis of pollution factors during construction period

1 ecological environmental factors

In the course of construction earthwork excavation of 100,000 m 3, completed a total of 80,000 m 3 earth backfill, as well as 20,000 m 3 spoil, will increase the amount of soil erosion in the short term.

52

Due to the land occupation and construction site of the project Xiejiawan Park Project and the Luxi

River Channel Improvement Project, it will have a destructive impact on the terrestrial vegetation within the construction area. The excavation and disturbance of the riverbed of the Luxi River channel treatment project will have certain impact on the biomass and habitat of aquatic organisms in the river and sediment, mainly due to the impact of increased water suspended matter caused by river disturbance. After the completion of the construction, the impact of the disturbance water quality was eliminated, the increase of suspended solids in the water was alleviated, and it was restored after the completion of the construction. The treatment of the Luxi River, the river waterscape and the re- construction of the ecological vegetation on both sides of the river will have a certain impact on the two banks of the Luxi River and the integrity of the terrestrial and aquatic ecological environment, forming a new artificial ecosystem.

During the construction period, the pollutants from the exhaust gas mainly come from the exhaust of various construction machinery and transportation vehicles, road dust generated during construction work such as foundation excavation and building materials transportation, and dust will be caused by large-scale earth excavation, turning and stacking.. A small amount of malodor produced during the dredging process.

3 wastewater

The wastewater during the construction period is mainly the domestic sewage generated by the construction workers, the construction wastewater generated by foundation excavation, dredging, washing, silt dumping, etc.

4 solid waste

The solid waste during the construction period is mainly the domestic garbage of the construction workers. During the construction of the project, the construction of the campsite, the existing river clearing construction waste and the abandoned earthwork and silt during the construction process.

5 noise and vibration

The tamping machine, excavator, bulldozer, mixer, hoist, vibrator and other mechanical equipment used in the construction process and the transport vehicle will generate a certain amount of noise and vibration during operation.

53

6 Some migrant workers may enter during the construction process. Due to the uneven quality of these personnel, it may cause certain inconvenience to the surrounding safety within a certain period of time. Therefore, it is necessary to strengthen public security management during construction and construction, and strive for local related Departmental assistance.

During the construction period, the living conditions and sanitary conditions of the workers are relatively poor, and the labor intensity is also large, so it is easy to cause various diseases. Wastewater, various construction wastes and garbage in the daily life of workers during construction will cause various germs to germinate and spread diseases.The dust generated during construction will enter the human body with the breathing of the workers. Excessive retention will endanger human health. The noise generated by various machines during the construction process is excessive, which may cause harm to the construction personnel. Construction machinery has certain dangers during operation. It must be operated strictly in accordance with the operating specifications during construction. It is strictly forbidden to operate illegally or operate the machinery after drinking. Since all activities during the construction period are temporary on the construction site, the harm to human health is also staged, and the damage will disappear after the construction.

Factors runtime environment analysis after completion of the project.2.2 6

(1) Analysis of environmental impact factors during the operation period of Xiejiawan Park

This project is a park construction project. After the completion of the project, it is mainly a place for tourists to relax and have no food and beverage. The main pollutants are:

1 exhaust gas

The exhaust gas during the service period of the park is mainly the exhaust gas generated by the exhaust gas discharged from the automobile, the sewage treatment facilities and the public toilets, and the garbage collection point exhaust gas.

2 wastewater

The main sewage generated during the operation period of Xiejiawan Park is domestic sewage and road rainwater.

3 noise

The noise generated during the operation period of Xiejiawan Park mainly includes certain noises, background music systems, social noise and traffic noise generated by the citizens' gardens during the

54

operation of the water pump.

4 solid waste

The solid waste generated after the project is put into use is mainly the domestic garbage of park visitors and park managers.

(2) Analysis of environmental impact factors during the operation period of the rectification section of Luxi River

Due to the operational characteristics of the river regulation project during the operation period, the Luxi River channel treatment project mainly affects the surrounding environment and is mainly affected by the ecological environment and surface water environment.

1 water, ecological environment impact

Qujiang River is the main river Guang'an City, is consumptive water municipal sewage and industrial waste water Guang'an City, Luxi River is a tributary of the river canal. Through the comprehensive improvement of the environment in the Luxi River Basin, especially the dredging and landscaping of the river channel, the water environment of the Luxi River can be effectively protected, which will have a beneficial impact on the downstream aquatic environment and the ecological environment on both sides.

Due to the waterscape and the construction of the ecological environment on both sides of the strait, the formation of urban green belts will be conducive to the construction of urban artificial ecosystems and the formation of new urban ecological environments with point-and-line integration.

2 hydrological situation impact

The implementation of the project can effectively improve the flood control and drainage standards of the Luxi River and promote the socio-economic and ecological sustainable development of the Qianfeng District.

After Luxi river control project is completed, increasing the downstream river flood discharge capacity, reduced river erosion, increase the width of the river, erosion capacity decreases, so can Luxi River from 20 year flood standard.

6. 3 major pollution sources and control measures

6. 3.1 Main main pollution sources and control measures during construction period

(1) Air pollutants

55

During the construction period, the air pollution mainly comes from the transportation and stacking of building materials (cement, sand, stone); earthwork filling and on-site stacking; concrete mixing; stacking and cleaning of construction materials; trench backfilling; pavement laying; transportation vehicles during construction period run.

1 mechanical equipment exhaust

Equipment main exhaust gas containing SO 2 and NO x emissions Watian site during construction activities, such as the types of fuel transport power machinery. Since the construction of fuel-powered machinery is indirect operation and the amount of use is small, the emitted fuel-gas pollutants will have a discontinuous impact on the air quality at the construction site. Since the fuel used by the construction workers is prohibited from using coal, the clean energy liquefied gas is used, and the pollution caused by combustion is small and negligible.

2 dust

The construction dust mainly comes from the on-site handling and stacking dust generated by construction materials (cement, sand, stone, etc.); the dust generated by the cleaning and stacking of construction waste; the backfilling of trenches; the road dust caused by people coming to the road. During the construction period, TSP pollution mainly occurs in the operations of foundation excavation, raw material transportation and cement use. The analogy method was adopted to select the measured results of the Chengyu Expressway, which was also built in the hilly area, for comparative analysis. In the case of clear weather and no sprinkling on the construction site, when the earthwork loading, unloading, transportation and on-site construction work were carried out, the downwind direction (wind speed) 2.4m / s) The concentration of TSP (mainly sand dust) in the range of 50~ 150m can reach 5.0 ~ 19.7mg / m 3, when the lime soil loading, unloading, transportation and mixing operations, in the downwind direction (wind speed 1.2m / s) 50 ~ 150m The range TSPconcentration can reach 0.8-9.0mg/m 3, which indicates that the TSP pollution of the ambient air in the evaluation range is serious.

The project is located in the urban planning and construction, and it is necessary to suppress the impact of building dust on the atmospheric environment, animals and plants.According to the document of the Sichuan Provincial People's Government (Chongfu Fa [ 2014 ] No. 4), the third key task in the

Sichuan Province Air Pollution Prevention and Control Action Plan 4 to strengthen the construction

56

site and road dust pollution remediation. To strictly control the dust environment management of construction sites, the following measures must be taken:

1) Strictly refer to the construction site in project site management The management of “six must” and “six inaccurate” principles means that wet operation must be carried out, urban road sections must be fenced, roads must be hardened, flushing facilities must be installed, cleaning personnel must be provided, and construction sites must be cleaned regularly; Vehicles with mud out of the door, not allowed to transport slag vehicles to top load, not allowed to cast slag at high altitude, no on-site mixing of concrete, no water accumulation on the site, no on-site burning of waste, effectively curb dust pollution on construction sites.

2) The concrete mixing station shall be equipped with dustproof measures such as construction enclosures, such as mixing in buildings; it can effectively control dust pollution.

3) The construction site should be sprinkled in a timely manner on non-rainy days, including the road sections under construction and the main transportation roads. The frequency of watering is determined by the on-site supervisors according to the actual situation.

4) Powder materials such as cement and lime should be filled or bagged. It is forbidden to transport in bulk. It is strictly forbidden to scatter dust during transportation. When storing, it should be piled up in the warehouse or covered with tarpaulin.

5) Place dust-proof mats at the exit of the construction site, and transport vehicles at the construction site must wash the car body and tires with water. The transportation of earth, sand and stone materials is prohibited from overloading. The height of the loading shall not exceed the compartment board and the tarpaulin shall be covered. It is strictly forbidden to scatter along the way.

6) When the wind speed is above 4 or above, it is recommended that the construction unit should suspend the excavation of the earthwork and take measures such as covering the pile and moist to effectively reduce the dust pollution;

7) Timely clearing and transporting construction waste, and measures such as covering should be adopted for temporary transportation. Vehicles that transport dust, sand, stone, cement, earthwork and other dust-prone materials must be tightly sealed. No spills are allowed.

8) Distribute dust masks to construction workers to reduce the damage to the health of construction workers.

57

9) Temporary dumping site should be regularly sprinkled with water to reduce the impact of dust on the surrounding environment; a closed barrier not less than the height of the stacked materials should be placed around it; the material area and road boundaries should be divided, and the scattered materials should be removed in time to keep the road clean and tidy. And clean in time.

10) If the road and pipeline construction piles for more than 48 hours, full dust prevention and other measures should be taken.

11) The waste transportation vehicle adopts a closed vehicle body. A car wash platform is arranged inside the entrance and exit of the transportation vehicle, and the drainage facilities are improved.

Before the vehicle leaves the site, the tires and the body should be washed to prevent the soil adhesive tape.

12) Vegetation protection measures:

A, taken sealed off construction, construction dust falling preventing leaves nearby vegetation.

B, transport routes and yard, residue field, earthworks etc. temporary yard away from the building to the surrounding forest, through which the absolute prohibition; regular trees road transport in the past were watering flushing.

After taking the above measures, it is still impossible to completely solve the problem of dust emissions, especially sporadic unorganized emissions. The construction unit shall carry out environmental protection education and work for the construction workers, and civilized construction.

3 asphalt smoke

The road reconstruction project uses asphalt concrete pavement. The base layer concrete of this project comes from the purchase of commercial asphalt. The asphalt used in SMAasphalt pavement is directly purchased from the municipal asphalt plant, and asphalt compaction is prohibited on the site. During the pavement construction phase, a small amount of asphalt smoke is generated during the pavement laying process. Paving the way for a short time, asphalt paving smoke produced during little, little impact on the local environment.

4 silt odor

The dredging method of the Luxi River adopts dry dredging, and the river channel is divided into several construction sections. After the construction diversion, the river construction surface is aired for several days, the water carrying operation is minimized, and then mechanical excavation is carried

58

out. Located in the abandoned silt area of the river remediation landscape area. Dry dredging can be equipped with more machinery, increase the working face at the same time, shorten the working period, the cleaning project is intuitive and thorough, the project occupies less land, and the sludge has a low moisture content. According to similar engineering analogy, the sludge contains water. The rate is generally about 20%, and it is easier to re-cultivate in the abandoned silt area. The odor generated by the sludge during the dredging process has a certain influence on the surrounding environment, and the odor intensity is analyzed by an analogy method.

Remarks The stench strength is graded based on the olfactory threshold of odor. China

divides the stench intensity into 6 levels.

(2) Waste water

During the construction period, the wastewater generated includes the production wastewater and the domestic wastewater of the construction personnel.

1 domestic wastewater

The project Xiejiawan Park is located in the newly planned urban construction area of Qianfeng

District. The surrounding residential quarters have not been put into operation. The construction party plans to set up a construction camp in the project area. Within the scope of permanent land occupation, no new land is occupied, covering an area of 100m. 2, mainly as a staff office life. Construction scale Luxi River, river training works relatively small, and the sub-construction, construction located in the forward area of the city area, improve the surrounding community service facilities, Luxi River

Improvement Project area is not set construction camp life, relying on domestic waste water surrounding the construction has been built Municipal facilities processing. When the peak

59

construction period of the project work staff of about 120 people, including 80 construction workers

XIEJIAWAN park, Luxi River Improvement Project construction staff of 40 people. Luxi River

Improvement Project construction site work camps without facilities, no site canteen and dormitory construction site, so the construction of waste water and domestic sewage is mainly construction workers, according to 1 0L / R person ▪ d is calculated, XIEJIAWAN park construction press of 15 0L

/ person / d domestic water meter, then the domestic water consumption peak day 12.40 m 3, the amount of domestic sewage at 8 meter 5% water, about 10.54 m 3 / d.Analogy the same type of effluent quality, major pollutants in wastewater as CODcr, BOD 5 and SS, the concentration of each pollutant: CODcr350mg / l, BOD5200mg / l, SS250mg / l.

The project XIEJIAWAN construction engineering construction workers sewage mainly concentrated in the construction camp (area) produced, the EIA requirements in sewage construction camp offers centralized collection scratch pool construction camps, timely use of municipal suction truck transported to the municipal sewage disposal plant, the construction of this kind can ensure effective sewage treatment, avoid sewage discharge standards do not contaminate surface water.

2 construction wastewater

Construction site wastewater is concrete curing wastewater, concrete mixing wastewater, equipment flushing water and drainage sludge drainage. This small amount of Concrete Engineering, according to the same analogy engineering, water conservation produced about 5 0.00 m 3 / d, this section does not contain hazardous substances in waste water, the main pollutants PH, SS like. Construction site machinery washing waste generated is about 2 0.00 m 3 / d, the main pollutant is SS, oil. The sludge produced by dry dredging has a low moisture content, and a silt dam, anti-seepage layer, sedimentation tank, etc. are built in the abandoned silt area. According to the analogy, during the natural drying process of the abandoned silt area, the displacement is about 2.00 m 3 / d, mainly SS, due to the low water content, the sludge drying process is faster, according to the feasibility study unit introduction and similar engineering comparison, generally two or three months can be used as planting soil for re-cultivation.

Luxi river bed is narrow, low flows in small, only 0.0 6 m 3 / s, there may be dry river phenomena, suitable for dry dredging. The river dredging is carried out in the dry season. After the construction diversion, the river construction surface is aired for several days, and then excavation is

60

carried out. Compared with the wet dredging, the disturbance diffusion degree and the disturbance range of the river bottom sediment are relatively small, and the sludge contaminant is relatively small.

The amount of release is small, resulting in a much smaller increase in the concentration of local suspended matter in the channel. At the same time, in order to avoid the influence of suspended solids on the surrounding water body during construction, it is recommended to use a bag that is relatively strong and not easy to leak during dredging. There is no mature estimation method for the amount of suspended sediment produced by water diversion during construction diversion. Compared with other similar projects, the SS concentration increases from 30 mg/L to 50 mg/L, with an intermediate value of 40 mg/L. The increased amount of suspended matter is 1.2 g./s.

The main component of sediment transported to temporary spoil field is not available excavation reuse of excess loam, loam and other miscellaneous low moisture content, beforeanalogy downstream region Luxi River Improvement Project experience will be in the process of landfill A very small amount of leachate is produced and collected by setting up a collection tank. After the precipitation treatment, the supernatant can be discharged into the surrounding forest land.

Analogy investigation produce the amount of water quality, life and production statistics sewage wastewater projects in major pollutants, Table 6.3 - 2.

As the production wastewater in the construction period is scattered, it is difficult to concentrate on treatment. Sedimentation tanks are constructed at each construction site, and multi-stage sedimentation treatment is carried out on the production wastewater. For the washing wastewater, an oily wastewater collection tank is required, and the qualified units are entrusted after collection.

Processed, not directly effluxed. Since the water quality requirements for construction water are not very high, the treatment of effluent should be prioritized for reuse, and it can be used for construction ingredients, regional greening and road dust reduction.

The following treatment measures must be taken for construction wastewater during the construction period :

1) During the construction period of the project, machine maintenance and vehicle flushing are involved in the construction camp. A small amount of mechanical maintenance and cleaning wastewater and car wash wastewater will be generated. The oil-filled grit chamber will be set up near the machine repair site and the car wash site in the construction camp. Watering the car wash water and the site to prevent dust from polluting the environment. At the same time, the management and maintenance of fuel machinery and vehicles will be strengthened to effectively reduce the phenomenon of running, running, leaking and dripping, thereby reducing the amount of oily sewage generated. The domestic sewage generated from the construction camp of Xiejiawan Park is collected and treated by the grille and transported by tanker to the Qianfeng District Sewage Treatment Plant for discharge to the standard, which will not affect the water quality.

2) The project mainly uses commercial concrete, which will not produce a large amount of concrete mixing wastewater and sand and gravel washing wastewater. A small amount of wastewater can be provided with drainage ditch around the construction site, and the site wastewater will be collected and reused after being treated by sedimentation tanks. Spraying dust control at the construction site, construction wastewater is strictly prohibited from being discharged.

3) Set up drainage ditch around the Xiejiawan Reservoir, and build a small grit chamber at a certain

62

distance and at a low level in the section: as a concrete maintenance wastewater collection and treatment facility, all the treated wastewater after the sedimentation treatment will be reused on the pavement. For concrete maintenance, the submerged pump is used to pump the supernatant regularly or irregularly, and the grit chamber is cleaned regularly.

4) For the drainage of sludge dumping yards, the discharge water reaches the first-class standard of Integrated Wastewater Discharge Standard (GB8978-1996) after being placed in the multi-stage sedimentation tank, and then discharged into the Luxi River.

5) For domestic garbage, construction waste, and maintenance garbage, since it will cause pollution when entering the water body, it is required to organize recycling, classification, storage and treatment.

The materials that can be used should be used or submitted for acquisition, such as most papers. Wood, metallic and vitreous waste can be reused by the acquisition station. For those that cannot be used, it should be properly disposed of by the sanitation department, incinerated, incinerated, landfilled, and stored.

6) The foundation pit water generated by the excavation of the Luxi River is used for construction water after sedimentation.

(3) noise

During the construction period of the project, there are many types of working machinery. The noise during the construction period comes from construction machinery operation and automobile transportation in construction activities such as construction excavation and concrete mixing. According to the engineering analogy analysis, the main noise sources to be controlled are concrete mixers, excavators and other equipment, and the noise level is above 80dB. The operation of the construction machinery and the transportation of the transportation vehicles will have a certain impact on the acoustic environment around the construction area.

According to the analysis of the analogy of similar projects, road construction, operation noise value of the device follows Table 6. 3--3.

Table 6. List of 3 - 3 equipment mechanical noise

As the project construction will have a certain impact on the surrounding environment. Therefore, the

EIA requires:

1 Establish a sound management system

1) The construction unit shall report to the local Environmental Protection Bureau 15 days before the start of construction to explain the construction project, the site, the noise intensity that may be emitted and the noise prevention measures taken. After obtaining the approval of the Environmental

Protection Bureau, the construction unit will post the “ Anmin Notice ”. The name of the project, the construction content and time, the contact information of the project owner, the name of the construction unit, the person in charge of the construction site and the contact information, possible noise pollution and the prevention measures taken as the publicity content. At the same time, it actively contacts the environmentally sensitive points around the plot and establishes a good relationship of mutual understanding and mutual support.

1) During construction, the masses visit the reception station at the construction site to specifically

64

prevent the construction of disturbing people and people's disturbances from adversely affecting the normal construction progress of the project, and avoid or reduce the occurrence of disturbing people or people. Regularly carry out civilized construction education for construction workers, advocate civilized construction, and enhance the self-conscious awareness of all construction workers.

2 Construction site anti-noise control

1) Control of artificial noise. The construction site advocates civilized construction, establishes and improves the management system for controlling man-made noise, minimizes artificial loud noises, and enhances the self-conscious awareness of all construction workers against noise and disturbance.

2) Control of noise operation time.

Night (22: 00- 6:00 the next day) prohibit the construction work, daytime 12:00 -14 points prohibited the construction of high noise equipment. If it is necessary to carry out nighttime construction work due to special needs, the construction unit shall submit the application in accordance with the relevant laws and regulations on the 4th day before the night construction. The construction unit shall announce the nearby residents on the construction site one day before the night construction.

3) Reasonable use of construction machinery. Construction machinery and transportation vehicles are the main causes of construction noise. To reduce the impact of noise during construction period on sensitive surrounding areas, the construction unit should use advanced construction machinery and technology during the construction process, select low-noise operation equipment, and ban the use of countries. The mechanical equipment that has been eliminated is clearly arranged according to the site conditions; the muffler is installed in the medium and high frequency noise sources such as air compressors and fans.

4) Reasonably arrange construction tools. Rational arrangement of the construction unit during the construction construction machinery, as far as possible is disposed at the venue east side and a central, Kwong Procuratorate away, reinforcing steel processing facilities provided NOISE high processing room. After the initial completion of the underground project, the small equipment such as air compressors will be moved to the underground project under the premise of safe construction to reduce the impact of construction noise on the surrounding environment.

5) Actively improve production technology. The production operations should be developed as far as possible to the outside, and the amount of construction work and the contents of the work should be

65

constructed. With commercial concrete, it is strictly forbidden to use equipment such as concrete mixers that produce continuous noise.

6) Set the sound barrier. A hard enclosure noise of not less than 1.8m is installed around the construction site to ensure that the impact of noise during the construction period on the surrounding sensitive points is minimized.

3 Transportation Management

The transportation of vehicles should reasonably plan the transportation routes. When transporting vehicles through urban roads, it is forbidden to whistle and control the speed of the vehicles. At the same time, the transportation period should avoid the peak of residents' travel and rest periods.

Seriously implement noise prevention measures to achieve civilized construction, which can minimize noise disturbance during construction; with the end of the construction period, construction noise will disappear.

After the above prevention and control measures, the noise of this project can achieve the discharge standard.

(4) Solid waste and disposal measures

Construction of solid waste are mainly: dredging sediment, earthwork excavation muck, roots, gravel, etc., riverside building demolition construction waste was generated, material loss during transportation of materials, including sand, concrete, etc., paving and trimming stage stone, ash, building materials and other losses, construction workers' domestic garbage.

The construction land of Xiejiawan Park of this project mainly utilizes the land around the current

Xiejiawan Reservoir. The land area covers an area of 110,920 m 2, and theterrain of the project area is relatively flat. The construction process does not make major changes to the topography, maintain the existing terrain elevation, and excavate the fill. The amount is mainly derived from the construction of landscape facilities and the straightening of local routes such as main and secondary tours. According to the project construction design, two temporary dumping sites are set up for the temporary dumping of topsoil, which are located on the east side of the central part of the park block and the southeast corner of the park block. The total amount of earthwork excavation is expected to be 5.50 in the project of Xiejiawan Park. Wan m 3 (natural side, the same below), where topsoil stripping 01 100 m 3, stripping topsoil for post-green casing, to achieve the comprehensive utilization

66

of earth, and the temporary field bulldozers and other vegetation restoration measures carried out, the

The project is excavated and balanced, and no spoil is generated. The construction waste slag generated during the construction of Xiejiawan Park is about 0.8 million m 3, which is transported by the construction party to the construction landfill designated by the local department, with less adverse impact.

The project Luxi river control works of earth excavation total of 62 000 m 3, backfill and use most of the rest are spoil, spoil total is 25,000 m 3 (where the silt 05000 m 3), for the Some of the waste slag shall not be randomly disposed of and transported to the corresponding spoil ground for disposal. The construction waste slag generated during the construction of the project is about 0.3 million m3, which is transported by the construction party to the construction landfill designated by the local department, and the adverse impact is small.

When the peak construction period of the project work staff of about 120 people, including 80 construction workers XIEJIAWAN park, Luxi River Improvement

Project construction staff of 40 people. During the peak construction period of the project, there were about 120 operators, including 80 construction workers in Xiejiawan Park and 40 construction workers in the Luxi River channel improvement project. The construction site of the Luxi River channel improvement project is not equipped with campsites, and there are no construction halls and construction site dormitories. Therefore, the amount of daily garbage generated by the staff during the construction period is 0.5kg/d, and the daily garbage produced by the staff during the construction period of Xiejiawan Park The quantity is 1.0kg/d, and the project construction period is 10 months.

The maximum amount of domestic garbage generated during the construction period is 100kg/d, and the total amount of domestic garbage generated during construction is 30t.

This evaluation requires the construction unit to take the following prevention and control measures for the production of solid waste during the construction process:

1) The domestic garbage generated by the construction shall be collected in a centralized manner and disposed of by the local sanitation department;

2) After the completion of the project, dismantle the temporary construction facilities in the construction area, remove construction waste and various sundries, clean and level the surrounding domestic garbage, simple toilets, and sewage pits, and disinfect with charcoal and quicklime to make

67

construction sites. Return to work;

3) Each construction contractor shall arrange a special person to be responsible for the collection of production waste. Scrap iron, scrap steel, waste wood fragments, etc. shall be piled up at designated locations, and it is strictly forbidden to pile up indiscriminately;

4) During the transportation of domestic garbage and building materials, sealing or covering measures should be taken to avoid spilling or discarding rivers along the way, such as garbage, sand and gravel.

(5) Groundwater pollution prevention measures

This project river training works and municipal park construction projects, the construction involves formation including the first Quaternary Holocene on Soil (Q 4 Me), Quaternary Holocene Alluvial layer (Q 4 Al + PL) and Jurassic The Zhongxuan Shaximiao Formation (J 2 s) involves stratigraphic lithology of silty clay and mudstone. The construction unit of the construction process shall take the following prevention and control measures to prevent the pollution of the wastewater from causing pollution to the regional groundwater environment.

1 Strengthening the treatment of domestic sewage and production wastewater during construction period, the domestic sewage of construction workers shall be used for agricultural irrigation or reuse after pretreatment, and the production wastewater shall be used for watering and dust reduction at the site after sedimentation treatment;

2 The bulk stockyard adopts coverage measures to prevent soil erosion from contaminating groundwater.

3 The construction unit is required to be scientifically organized, rationally constructed, and the construction period should be shortened as much as possible to reduce the impact of groundwater pumping.

4 sections to organize the construction, to avoid the overlap of the groundwater level due to the excessive concentration of the precipitation wells in some sections.

5 The construction of the Luxi River channel improvement project should be carried out in the non-

69

flood period as much as possible, which can reduce the impact on the construction due to shallow groundwater depth.

The Quaternary New Territory Filled Soil (Q 4 me) low liquid limit clay layer and the Quaternary

Holocene alluvial deposit (Q 4 al+pl) have poor water-rich soil layer and the groundwater type is loose rock pore water. It is mainly recharged by atmospheric precipitation. The groundwater volume is limited by atmospheric precipitation. The amount of water is usually small and the supply and distribution are uneven. The roadbed construction of the proposed project will directly damage the

Quaternary strata, which will directly affect the recharge and transportation of Quaternary groundwater on both sides of the road along the route. However, since the groundwater supply source of the Quaternary stratum is atmospheric precipitation, the highway is a linear project with a relatively small area, which generally has a relatively small impact on the groundwater recharge of the formation, and has no obvious impact on the planned new urban area.

Overall, the groundwater sensitivity of the project area is low, and the groundwater resources are not abundant. The impact on the destruction and recharge of groundwater resources during the project construction period is generally small.

6. 2. 2 operation of the main major sources of pollution control measures and strong

After the completion of the comprehensive rectification project of Luxi River in this project, the water administrative system is managed in a unified manner. The project does not have a management room.

There is no full-time management personnel during the operation period. Therefore, there is no discharge of waste water, waste gas, noise and solid waste after the project is completed. The pollutants generated during the operation period are mainly domestic garbage, domestic sewage and social activity noise generated by the tourist activities of Xiejiawan Park.

(1) Exhaust gas

The exhaust gas during the service period of the park is mainly the exhaust gas generated by the exhaust gas discharged from the automobile, the sewage treatment facilities and the public toilets, and the garbage collection point exhaust gas.

1 car exhaust

The supporting road works of the park do not generate exhaust gas by itself, but because the vehicles after the road is built, automobile exhaust will be generated. The proposed project has an open parking

70

lot on the south side of the park. There are 30 parking spaces in total, and the automobile exhaust generated by entering and leaving the vehicle mainly contains THC, NOx and other pollutants.

2 sewage treatment facilities

This item in a block next to the public toilet provided. 1 th grill well, its capacity of 30m. 3 / D, sewage treatment grill well will have a certain amount of odor, mainly composed of H 2 S, NH2. 3 and other pollutants If improper handling will have a certain negative impact on the surrounding environment, the generated odor will be discharged to the roof of the building through a dedicated pipeline.

3 public toilets

The proposed project were provided with 1 toilets, use of the process will produce a small amount of odor. Through the air supply system of the air supply and exhaust system, the daily cleaning and regular disinfection of the staff, the odor of the public toilet has little impact on the environment.

4 garbage cans, garbage collection points

In this project, it is proposed to install garbage bins with “ recyclable ” and “ non- recyclable ” delivery ports in public areas such as main roads, secondary roads, sidewalks, management and service facilities, and public areas inside buildings. The garbage collection points set by the main production spots of each plate. Domestic garbage is mainly a substance that is easily fermented and deteriorated by some foods. It is odorous due to fermentation during storage, and it is easy to produce mosquitoes and flies, which has a certain impact on local environmental sanitation.

(2) Waste water

1 domestic sewage

After the proposed project is put into operation, the discharged wastewater is mainly the domestic sewage of park visitors and management personnel. The total domestic sewage of the project is 27.45 m 3 /d, which is 10019.25 m 3 /a, which is processed into the grid well. Refer to "first national pollution source census of urban life sewage capacity factor Handbook" survey data, the proposed project to produce a concentration of major pollutants COD 500 mg / L, SS 350 mg / L, ammonia nitrogen 70 mg / L, the amount of water pollutants see under The table shows.

A municipal sewage pipe network is built around the project Xiejiawan Park. After the waste water is treated by the grid well to reach the Class III standard of Integrated Wastewater Discharge Standard, it will be treated by the municipal sewage pipe network into the Qianfeng City Wastewater Treatment

71

Plant to reach the urban sewage treatment. The pollutant discharge standard of the factory (GB18918-

2002) enters the Qujiang River after the first-class A standard. The amount of sewage generated by the proposed project, the amount of sewage treatment plant entering the environment and the environmental input are shown in Table 4-4.

Forward sewage treatment plants (ie, the forward zone textile park sewage treatment plant) in 2015 Nian 9 months to build, 2017 Nian 4 was officially put into operation month. The sewage treatment plant has a final design scale of 100,000 tons per day and is implemented in two phases. The scale of the first phase is 50,000 tons per day, and the total planned land area is 120 mu, with a total investment of about 300 million yuan. The first phase of the project is divided into two phases. The first phase of the first phase of the project has been completed and put into operation. The daily sewage treatment capacity is 20,000 tons, covering an area of about 37 mu. After the completion of the first phase of the second phase project, the daily sewage treatment capacity can reach 30,000 tons. It is fully capable of meeting the domestic sewage treatment needs of the forward

72

city. The sewage treatment plant raw nitrogen and phosphorus removal process was the mature technology, simple process, desmutting is high and stable.

2 landscaping water

The garden maintenance water is mainly used in the season when the rain is scarce (the greening period is 180 days per year for 6 months). The plants in the park are sprinkled. The total area of greening is 82,278 m 2, calculated according to 2L/m 2.d. The water consumption is 164.56 m 3 /d and the annual water consumption is 29620 m 3 /a.

At the same time, during the daily maintenance of the park, the trees will be fertilized and sprayed frequently. When the rain weather comes, the pesticides will merge with the rainwater to form surface runoff. If it is not treated, it will flow into the surface water freely, which will affect the surface water quality. Therefore, the park strictly takes precautionary measures during the service period. Plant fertilization uses organic fertilizer. The evaluation requires that the construction unit should not use pesticides. It is recommended to use environmentally-friendly equipment such as insect nets, glue nets, trapping lights for pest control.

3 road rainwater

During the service period, the pollution path generated by the supporting roads to the nearby waters is mainly road runoff. When the vehicle maintenance condition is poor, faults, accidents, etc., the gasoline and oil contaminated road surface may be leaked. After the rain, the rainwater passes through the rainwater pipe network. Flowing into the Xiejiawan Reservoir and the Luxi River, causing pollution effects of SS, petroleum and COD.

(3) noise

The noise generated during the service period of the proposed project mainly includes the noise of the water supply system, the noise generated by the background music system, the social noise generated by the citizens' gardens, and the traffic noise. The water pump of the water supply system will also generate certain noise during operation. noise, the noise value of about 80 ~ 90dB (a), the background noise is mainly generated by the music system audio equipment, the noise value of about 80 ~

90dB (a); public travel noise is generally generated Park 60 ~ 70 dB (a), It is mainly in the daytime, and disappears as the crowd dissipates at night. At the same time, because the background music in the park mainly plays light music, and the sound system is arranged in the middle of the park, away

73

from the surrounding schools, the occlusion of vegetation such as trees and shrubs in the park has little influence on the sensitive points of the surrounding environment.

Traffic noise refers to the sound generated by the vibration of the car itself, the engine running, the friction between the tire and the ground, etc., and the degree of noise influence is directly related to the type of car, the driving state of the car and the traffic volume. The noise is an energy pollution, which has attenuation characteristics in the transmission process. In addition to the distance attenuation under normal conditions, there are also attenuations caused by atmospheric absorption, wind direction, temperature gradient, ground conditions, trees, and barriers. When the car enters the parking lot, it is generally in an idle state, and the noise source generated by it is generally small.

Between 60~70dB(A), the noise will disappear immediately after the vehicle stops and the flame is extinguished.

During the service period, the traffic noise of the vehicles in the park will bring different degrees of noise to the residents on both sides. Due to the large amount of vegetation on both sides of the roadway in the park, the necessary protective measures such as strengthening the greening and setting the speed bumps, etc. The impact of traffic noise can be better controlled.

(4) Solid waste

The solid waste generated after the project is put into use is mainly the domestic garbage of park visitors and park managers.

Park visitors by 0.2 kg / d · calculation person daily Visitors park is 1 500 people, the amount of garbage produced 300 kg / d, generating annual capacity of 75 t / A; public facilities and management staff of 5 people, trash The amount of production is calculated according to 1.0 kg/d· person, and the generated domestic garbage is about 5 kg/d, and the annual production is 1.83 t/a. The domestic garbage generated by the project is collected and processed by the sanitation department.

Referring to "the EIA Handbook" on a formula related data, grill well the total amount of sludge generated approximately 3. 00 t / A, the sludge produced by specialized units at the disposal of

Qingtao regular sludge generated is collected and processed by the sanitation department.

In addition, weeds, trimming and so on in the garden maintenance process will produce a certain amount of garden garbage, mainly dead branches and pruned branches and lawns. The average daily production is about 200kg/d, and the annual production is about 73t/a.. Garden garbage is collected

74

and transported by municipal vehicles to urban landfills.

Main ecological impacts, protective measures and forecasting effects: The project consists of two sub-projects, namely the new Xiejiawan Park Project, the comprehensive treatment of the Luxi River Logistics Park section of the Qianfeng

77

Cityand the landscape project on both sides of the river. Due to the inconsistent nature of the two subprojects, their ecological environment impacts are different. This evaluation separately describes the ecological impact assessment of the project construction. 7.1 Ecological Environment Impact Assessment of Xiejiawan Park Construction The proposed project area is located in a city park XIEJIAWAN ecosystem-based, according to affect the characteristics of the regional ecological environment and the characteristics of the project, the ecological environment to make a major impact prediction and analysis from the construction period of service in two stages. 7.1.1 Ecological environmental impact assessment during construction period (1) Environmental impact analysis of land use The land within the newly added land of the project is mainly cultivated land represented by wasteland. The topography is mainly shallow mountain. Some farmers in the park are cultivated here. Most of the vegetation on the mountain is economic forest, mixed forest and vegetation (weed grass), and is being demolished. At the same time as the private housing within the scope of the project, the existing reservoir infrastructure (dam, flood ditches, etc.) is retained. The construction of Xiejiawan Park will drive the regional urbanization process. It is the transformation of the land use structure of the agricultural land mainly in the region to the urban construction land, which will promote the development of the tertiary industry in the Qianfeng District and promote the land use in the adjacent areas. The value will increase. In general, the impact of construction land occupation on land use has its advantages and disadvantages. During the process of land acquisition and demolition, theQianfeng District Government, the land and civil affairs departments properly solved the negative impacts of land occupation to a lower level; the detailed land use planning was formulated for regional land use, and the proposed project was used as a regional plan. The important components and improved infrastructure will greatly promote the economic development of the region. After adopting the above measures, the impact of the project on land will outweigh the disadvantages. (2) Evaluation of the impact on soil erosion Soil erosion is mainly generated during the construction period of the project. During the construction process, the original landform will be disturbed and damaged, and the water and soil conservation facilities will be damaged. The original soil erosion protection system will be destroyed. The large-scale surface disturbance, especially the excavation during the earth-rock field, will inevitably increase the soil erosion intensity; backfilling and temporary The stacking of soil is also an important source of soil erosion. During the natural recovery period, surface disturbance activities will basically stop, and soil erosion in the project area will decrease year by year and tend to be stable. According to the construction characteristics of the main project to determine the impact factors of soil erosion, based on analysis and

78

evaluation, to determine the predicted time period, contents and methods of construction could damage the original topography of soil and vegetation conditions, the number of new and Dregs Reasonable prediction of the amount of soil erosion and the potential damage caused by soil erosion. According to the degree of soil erosion hazard combined with the characteristics of engineering construction, topography and landform, and site conditions, different protective measures are taken to provide a scientific basis for rationally arranging various prevention measures and effectively preventing soil erosion caused by engineering construction. 1 Soil erosion Features Soil erosion in the project area is dominated by hydraulic erosion, which is mainly characterized by surface erosion. According to the natural conditions such as topography and climate of the proposed project area and the construction process analysis of the project, the soil erosion of the project has the following characteristics: 1) The lost area is in a planar and linear distribution During the construction of the project construction site, the soil erosion is mainly distributed in a plane shape; the soil and water loss during the construction of the road and pipe network in the park is mainly linear. 2) Soil erosion is mainly concentrated in the construction period The soil erosion caused by the construction of the project is mainly caused by the construction of the site during the construction period; after the completion of the project, the exposed surface is covered by structures or vegetation, and the amount of soil erosion is gradually reduced. Therefore, the soil erosion caused by this project is mainly concentrated in the construction period. 2 Causes of soil erosion There are many factors affecting soil erosion, which can be divided into two categories: natural factors and human factors. Natural factors mainly include climate, topography, soil, geology and vegetation. They are the basis and potential factors for soil erosion. Unreasonable human activities are the dominant factors causing accelerated soil erosion. During the construction of the development and construction project, a large number of artificial activities were added, which disturbed the original landform to varying degrees and affected the soil erosion in the area. However, different development and construction projects have different degrees of impact on soil erosion due to geographical location, project type and construction process. During the construction period, the reason for the increase of soil erosion was the short-term high-intensity human disturbance, which caused the original topography and soil vegetation to be destroyed. The main performances were as follows: 1) Changed the original natural waterway and created a new possibility of gully erosion; 2) Destroying the original surface vegetation, causing the local ground to be exposed for a

79

period of time, increasing the possibility of surface erosion; 3) Mechanical rolling makes the ground hardening flow coefficient increase, which intensifies the intensity of water erosion; 4) A large amount of spoil and waste slag are piled up loosely. In case of heavy rain, serious soil erosion will occur. 3 Soil erosion prediction The total land area of the project Xiejiawan Park is 166,393 m 2, of which the park has a land area of 114,407 m 2 and a water area of 5,1986 m 2. During the construction process, the land leveling, high and low filling will loosen the surface soil, and the temporary storage yard, material yard, etc. will be easy to produce soil erosion. The project XIEJIAWAN park construction process of earth excavation volume 55000 m 3, backfill the amount of 53 900 m 3, backfill backfill in the main, trails, green casing and a concave line revetment construction of landscape water at low venue is located. The proposed project is located in Xiejiawan Reservoir of Qianfeng District, with a long construction period. The land area belongs to the construction site and the exposed area of the surface excavation is large. At present, most of the proposed areas are wasteland, and the topography is shallow hilly slope. The loose topsoil during the construction period is prone to soil erosion under the surface runoff and heavy rain. The spoils generated during construction are prone to water and soil if not properly disposed. Loss. It is bound to cause some degree of influence on the water environment XIEJIAWAN reservoir, increasing pollution of the reservoir XIEJIAWAN, increase turbidity, increased content sediment. Soil erosion is determined by the US General Soil Loss Equation (USLE). The mathematical model is as follows: A0.247RK LS C p e e I I t M  A F SS Where: A - average soil loss per unit area (kg/m 2); R e - rainfall erosion factor; K e - soil erosion factor; L I - slope length factor, L = (0.0451I) m, I is the slope, m is a constant; S I - slope factor, S = 0.065 + 4.5I + 65I2; C t - vegetation cover factor; P——the erosion control factor; M SS - soil erosion, t/a; F——the area of the lost area, km 2. When R, L I, S I, K, P remain the same or compared to the large area lost area, the change is small and negligible. Then A will change with the change of plant cover factor C, and the

80

above formula is simplified as: A C 1  1 A C 2 2 Where: A 1 ─ local local erosion intensity; A 2 ─ the intensity of erosion after surface change; C 1 - local natural plant cover factor; C 2 ─ Plant cover factor after surface change. During the construction period, the bare ground plant cover factor was taken as 1.0, the operational recovery period was taken as 0.5 in the near future, and the natural plant cover factor was taken as the mixed crop value of 0.2. After the completion of the building, the land occupation and road occupation are all hardened, and the rest is green land. There is no bare ground surface, and the coverage factor is 0.1. By referring to the calculation of soil erosion in the same area, the water and soil loss prediction, if no erosion control measures are taken, the annual water and soil loss during the construction period of the proposed project area is 12.58t. Simplified equation to estimate the change of the construction, soil erosion recovery operations, the prediction results in Table 7.1 --1. Table 7.1 - 1 Soil erosion in different periods period Soil erosion (t/km 2 ·a) Soil erosion (t/a) status quo A 1 2.57 Construction Period 5 A 1 12.58 Recovery period 2.5 A 1 6.43 After completion 0.5 A 1 1.29 According to the simplified equation calculation, the amount of soil erosion during construction is about 5 times of the natural loss, and the recovery period is about 2.5times of the natural loss. In the heavy precipitation season where heavy rains occur frequently, soil erosion will also increase. 4 Soil and water conservation measures 1) The soil erosion plan shall be prepared in accordance with the requirements in the early stage of construction of the project. The construction unit shall strictly follow the technical requirements of the soil erosion plan. 2) The project starts with the interception ditch around the Xiejiawan Reservoir to prevent muddy water from entering the reservoir. 3) The excavation width and the width of the construction work belt should be strictly controlled to minimize the damage to the vegetation along the road and the surrounding facilities. 4) Control the construction work time and try to avoid large-scale earthwork excavation

81

work during the rainstorm season. 5) During the construction period, the project should be rationally designed to achieve district excavation, so that the inevitable soil erosion caused by theconstruction is reduced to a minimum. 6) According to the actual conditions of the construction area, it is necessary to organize the construction plan of the construction area in an organized manner, reasonably plan the temporary dumping of the slag and spoil, and build a grit chamber, drainage ditch, fort, retaining wall, slope protection, etc. Impact on surface runoff. 7) The abandoned stone should be properly disposed of and used as much as possible for the construction of the access road, slope protection project, flood control dam, etc., and should not be piled up in the spillway to prevent flood discharge. 8) During the construction process, when the excavation section cannot be recovered immediately, the film should be covered with loose topsoil to reduce rain erosion. 9) After the completion of the construction, the greening will be carried out immediately around the house, on both sides of the road, in the open space, etc., and the restoration and reconstruction of the vegetation will be done well, so that the slope is stable and the rocks and topsoil are not exposed. 1 0) During the construction period, special personnel should be set up to supervise and supervise the problems of temporary excavation, spoil disposal, and trench backfilling during the construction process, so as to minimize the discharge of sediment. 11) The water and soil conservation measures during the operation period are mainly to strengthen the ecological construction. There must be no bare soil, and the soil and water conservation facilities should be inspected regularly, and problems should be repaired in time. At the same time, further improve the greening measures. (3) Impact assessment on surface vegetation The land in the new land use area is mainly cultivated land, and the topography is mainly shallow mountain. The vegetation on the mountain is mostly economic forest, mixed forest and vegetation (weed grassland), and there is no endemic species and rare species distribution. The impact of project construction on the vegetation in the assessment area is mainly due to the project land occupation and construction site, which partially disappears the vegetation within the occupied area, which will inevitably lead to the reduction of various vegetation areas in the assessment area, the decrease of biomass and ecological value, and the composition of vegetation. The number of individual species of plant species is reduced, and may even lead to ecological problems such as changes in flora components and consequent invasion of alien species.According to the on-the-spot investigation, the current types of vegetation in the evaluation area are mainly farmland, economic forest, mixed forest and vegetation (weed grassland). These vegetation types are simple in biodiversity, small in biomass and ecological in general. Vegetation types are more common around the evaluation

82

area; the project construction makes full use of the original vegetation, and preserves part of the vegetation that can be used as a landscape after the project is completed; at the same time, after the project is completed, large-scale greening will be carried out on the project area, which is common in the introduction area. Tree species such as camphor, eucalyptus, ginkgo, and red maple, so from the perspective of vegetation and plant protection, project construction has less impact on it. (2) Impact assessment of terrestrial animals During the construction period, various temporary buildings, permanent buildings, construction of transport roads, and mining of soil and stone materials, stacking, etc. all need to occupy a certain area of land, so that the habitats of dryland fauna and barren hill shrubs are reduced. The impact analysis is as follows: During the construction period, basic excavation, quarrying, earth borrowing, road repairing, and transportation operations all produce certain mechanical noise, which will cause certain noise pollution, causing the construction area and surrounding animals to evade response and fleeing around the construction area. As a result, the density of wild animals near the construction area has decreased. The dust and dust generated by the processing of sand and gravel to form dust pollution and the pollution caused by the transportation of automobile exhaust gas may cause some small and medium-sized animals to temporarily move out of the construction area. However, this impact is temporary and reversible. After the completion of the construction, with the implementation of large-scale greening, the green coverage of the project area will increase, contributing to the growth of common species. And the project is mainly small wild animals, such as squirrels, reptiles, amphibians, etc., mainly for common species and widely distributed. Therefore, the impact of project construction on animals is limited and partial, and is acceptable. (5) Impact assessment on the landscape The leveling of the site during the construction of the project and the mechanical rolling and trampling by the construction personnel will cause loss or damage to the original green vegetation around the construction site. After the construction of the project, the earthwork of the construction site will be excavated and transported, disturbing the original landform, and the green space will be damaged to varying degrees. In the construction area, various raw and auxiliary materials, construction facilities, spoil and slag should be piled up, and the construction site should be laid. If the arrangement is unreasonable, the whole construction site will be messy, which will have a certain impact on the urban landscape and make the regional ecological environment. The quality is degraded, but this effect is short and will end with the end of construction. Temporary dumping site is set up in the site for temporary stacking of topsoil. The topsoil is used for later greening and covering soil. The temporary stacking time of topsoil is 3 months, which realizes the comprehensive utilization of earth and stone. The temporary dumping site

83

uses the filling woven bag for blocking. The surface of the soil is covered with plastic color strips, and temporary drainage ditch is set up in the vicinity. Temporary grit chambers are set in the downstream part to increase the blocking and covering of sand, gravel and other building materials, and vegetation restoration for temporary piles. Measures. (6) Impact assessment on biodiversity The construction of the project will cause fragmentation of the plant habitats in the project construction area, islands, and road traffic will have a greater impact on the animals and plants in the project area. This impact is also reflected in the impact on biodiversity, and the main performance Loss of diversity in regional communities.Due to the development of the project, the destruction of regional vegetation was first caused, and the urban plant community with strong artificial influence, including artificial green vegetation and a small amount of wild vegetation adapted to the urban environment, resulted in the simplification and community of plant communities in the project area. The simplification of the structure level and the reduction of the number of animals and plants of the same species. The project area is developed and used as a service facility, road traffic system and artificial green space. It is bound to cause loss of community diversity of semi-natural plantations and crops. Although artificial green space is re-established, the structure and integrity of the community will be affected. 7.1.2 Eco-environmental impact assessment during service period (1) Evaluation of the impact of “ three wastes ” discharged during the service period on the ecological environment The Xiejiawan Park in this project has very little exhaust emission during the service period. The domestic wastewater is discharged into the municipal pipe network after biochemical treatment, and has little impact on the water environment. The solid waste generated is general solid waste such as domestic garbage, garden garbage and biochemical pool sludge. After being classified and collected, it is sent to the garbage dump for unified treatment, which has little impact on the ecological environment of the site. (2) Impact assessment on regional microclimate After the completion of the proposed project for the new green an area of 82278m 2, compared with before the expansion was built environment greatly improved, there is the function of regulating microclimate effects on regional climate was a positive influence. Greening will increase the variety and quantity of plants throughout the region and will have a positive impact on the air quality of the project construction area. (3) Evaluation of the impact on the soil in the field The construction of the project has made the urban soil development deviate from the natural development process and shows obvious heterogeneity. If the cultivated soil becomes garden soil, the soil texture changes and the humus increases due to a series of improvement measures. In addition, due to the influence of urban architecture, there will be more building

84

debris or ash in the urban soil, which will become a soil with uneven nutrients, uneven texture, dryness and ventilation. For example, affected by urban roads and traffic, the soil on both sides of the road will increase the pH of the soil due to the mixing of cement and mortar residue. If the road is stacked on both sides of the road, it will contain more nitrogen and phosphorus. Pressure and pedestrian trampling will increase soil compaction; planting of street trees and other landscaping plants will also alter the nature of the soil. (4) Impact assessment on biodiversity 1 vegetation After the completion of the project, the agro-ecosystem in the proposed project area will become an urban landscape ecosystem. Vegetation while retaining the original vegetation on Fengshan Park, a lot of vegetation planting trees, shrubs and other vegetation so that the area be restored gradually increase the biomass, the destruction wasto be restored. The landscape construction plant is planted with the backbone trees such as ginkgo, camphor, and osmanthus, which are popular among Chongqing citizens. It combines sparse forests, jungles, lawns, etc. to create a rich plant landscape. The land planting plants are mainly trees, shrubs and flower fields. After the project is completed, there are hundreds of new trees, shrubs and flower plants. After the completion of the project, the plant species increased greatly compared with that before the completion of the project, and the newly planted terrestrial plants are currently existing landscape plants in the eastern Sichuan region. No exotic species are introduced, and the vegetation covers a large area and a large number, which can make the ecological effects of the project Better play. Therefore, after the completion of the project, the vegetation and the number of regional vegetation increased compared with that before the completion of the project. The water body of this project is mainly landscape water body. The planting of aquatic plants in landscape water body not only has the function of landscape, but also provides more habitats and creates ecological diversity. More importantly, aquatic plants are beneficial to close the sediment and absorb some nutrients in the water body. Salt and harmful substances reduce the concentration of nitrogen and phosphorus in landscape waters to purify water. In addition, aquatic plants also remove and precipitate pollutants and inhibit blue-green algae blooms. The proposed project is equipped with aquatic plants of different heights, different forms and different ecological groups in the design. In the design of the species, both the landscape effect and the water purification effect are taken into consideration. The landscape effect is mainly reflected by the emergent plants and the floating leaf plants; the purification effect is mainly reflected by the submerged plants. Emergent plants grown in revetment landscape water line, as the main choice loosestrife, Cyperus emergent plants and the like, as shown in Table 7.1 -2. Table 7.1 -2 List of types and characteristics of emergent plants ECOLOGICAL CATEGORY PLANTING PLANT PREPARE NOTE

Planted aquatic plants can play a role in stabilizing water quality. 2 aquatic animals The landscape water area of the project is 5,1986 m 2, which is the area of the original Xiejiawan Reservoir. The species and quantity of ornamental fish are stocked in the landscape water body, which can improve the food chain and food network structure of the artificial aquatic ecosystem and improve the aquatic ecology. System stability. The types and characteristics of aquatic animals in the landscape waters of the proposed project are detailed in 8-3.

Small creatures are taken as food, and other rotifers, Filter Rotifer crustaceans, and algae are also eaten. feeding Filtering bacteria in the water, unicellular algae and Zooplankton Cockroach protozoa The selection of filter-feeding fish is dominated by ornamental fish such as koi, and a small amount of omnivorous fish is placed after the aquatic plants are grown.Through the feeding of algae in the upper layer of fish in the water body, the absorption of nutrients by aquatic plants, the transfer and enrichment of nutrients by aquatic animals, the purpose of water purification is achieved. Filter-feeding zooplankton mainly produces filter-feeding zooplankton such as rotifers and cladocerans, and filter-feeding zooplankton can also play a role in filtering algae. Molluscs mainly store benthic animals such as snails that feed on benthic algae in water. The density of benthic animals is preferably 20 to 40 g/m 2. After the proposed project is completed, the landscape water body can increase the types of aquatic animals. Through the purification of aquatic plants and animals, the water quality of the water body will change in a good direction, which is conducive to the survival of aquatic animals. Therefore, the service period will not affect aquatic animals. 3 aquatic microorganisms Microbes are abundant and widespread in nature and are one of the important components of ecosystems. They can decompose the corpses and debris of animals and plants in nature, and absorb and transform some harmful pollutants into inorganic nutrients that are non-toxic or less toxic. Therefore, they are called “ scavengers ” in water bodies, which play a key role in avoiding secondary pollution of water bodies caused by aquatic organisms. In the body of water, a certain amount of microbial preparation is applied to make the microorganisms which decompose the organic matter predominate, and the decomposition and mineralization of the organic matter in the water can be promoted. The proposed project only uses microecological preparations in the event of an unexpected emergency in the water body. If the landscape water body is seriously polluted, it is usually not easy to put it. To sum up: After the project is completed, ornamental grasses reflects the landscape of the park, showing wild vegetation landscape, but also the introduction of common camphor, Luan tree, ginkgo, red maple and other trees in the area of green varieties will be introduced strict According to the relevant documents of Sichuan Province.Therefore, there is no invasion of alien species and ecological risks. After the completion of the project, the plant species will be greatly increased before the completion of the project. The vegetation coverage area is large and the number is large,

87

which can make the ecological effects of the project better. Therefore, after the completion of the project, the vegetation and the number of regional vegetation increased compared with that before the completion of the project. In addition, the planting of aquatic plants and aquatic animals in the proposed park landscape water not only has the function of landscape, but also provides more habitats and ecological diversity. More importantly, aquatic plants help to close the sediment and absorb some of the nutrients in the water. Salt and harmful substances reduce the concentration of nitrogen and phosphorus in landscape waters to purify water. In addition, aquatic plants also remove and precipitate pollutants and inhibit blue-green algae blooms. The proposed project is equipped with aquatic plants of different heights, different forms and different ecological groups in the design. In the design of the species, both the landscape effect and the water purification effect are taken into consideration. The landscape effect is mainly reflected by the emergent plants and the floating leaf plants; the purification effect is mainly reflected by the submerged plants. Through the introduction and analysis of the proposed community design of Xiejiawan Park, this evaluation believes that the construction of the project will increase the plant species in the project site, which is conducive to the maintenance and development of biodiversity. 5 pairs of project landscape impact analysis The quality of the ecological environment is closely related to the architectural landscape system. In ecology, the landscape is defined as “ a heterogeneous region formed by the interaction of ecosystems ”. The landscape is a carrier of the ecosystem and has a multi-level and complex structure. The landscape system has the following functions: First, the landscape serves as the energy flow and material circulation carrier of the ecosystem, which is closely related to the social material and cultural system. The second is also the most easily overlooked aspect, and it is the information of the social spiritual culture system. The source exists, and human beings constantly obtain various kinds of information from them, and then through the processing of human wisdom to form a rich social spiritual culture. 1) Impact on regional landscapes and scenery The proposed project of Xiejiawan Park was originally an agro-ecosystem. The terrain of the evaluation area is quite large. The construction of the project will completely change the original natural ecological landscape system and replace it with the artificial landscape ecosystem. From the perspective of the integrity of the natural landscape, the natural ecosystem has been damaged to some extent. The construction of the project will implement an overall plan for the area, and construct a relatively regular and outstanding style of art buildings, which will have a very positive impact on the artificial environment of the scenic area. The project area is the urban area landscape, focusing on the urban ecological park

88

landscape. The water landscape, vegetation types and color changes are the mainstays. The concentrated green space of the project construction will improve the fragmentation of the landscape patches in the previous urban areas, around the proposed project. For the planned urban residential commercial land, a coherent and coordinated urban center landscape area with the project will play an important role in the regional urban environment. After the park is put into use, it is reasonable to arrange walkways and plant green plants. Based on the original landscape, small landscapes such as small items and lightings are set up, and the original single landscape elements become a diversified and three-dimensional landscape. Greatly improved landscape heterogeneity and park beauty. After the completion of the proposed project Xiejiawan Park, among the terrestrial plants planted, the height of the trees is between 2.00 and 10.00 m, the crown width is between 2.00 and 7.50 m, and the breast diameter is between 0.10 and 0.45 m. Between 0.15 and 2.50m. It mainly uses the combination of green trees, fallen leaves and flowers to create a layered layout of ecological leisure space plants with rich seasonal changes, using tall trees as the key tree species, and rationally considering the planting methods of middle and lower plants, thus enriching the three-dimensional ornamental mode and forming an ecological A multi-layered landscape with a stable structure. After the proposed project is completed, the aquatic plants planted in the landscape water body are mainly composed of emergent plants, combined with the plant communities around the landscape water body, creating a rich leisure space layout, forming a landscape with stable ecological structure and enhancing visual sense. 2) Internal landscape analysis The landscape pattern includes the main landscape axis, the main architectural landscape, the landscape opening, the landscape core and the landscape nodes. The various parts are interconnected to form an organic landscape pattern system, forming an ecotourism route. 7.1.3 Ecological landscape environmental protection measures (1) Environmental protection measures for ecological landscapes in Xiejiawan Park are as follows 1 The natural and human landscapes in the park, especially the waters, vegetation, cultural landscapes, etc., should be kept in their original form and are strictly prohibited from being destroyed by humans. 2 Except for the tourist road and a small number of scenic spots, no large artificial buildings shall be built. 3 The construction in the park is strictly in accordance with the overall planning of the Qianfeng District. The number, location, scale and style of attractions, trails and service facilities must meet the requirements of the overall planning. In addition to the overall planning scope, if new construction projects are required, it is necessary to organize expert

89

arguments, propose specific plans, and report to the relevant departments at the higher levels for approval. 4 The number of tourists in the park is controlled within the environmental capacity, and it is forbidden to enter the industrial enterprises in the park. 5 It is forbidden to set up industrial and mining enterprises that pollute the environment and water sources near the park. (2) Protection measures for landscape water ecosystem Ecologically comprehensively control the landscape waters in the park, and comprehensively consider the design from the perspectives of revetment, natural water, aquatic plants and aquatic animals to reduce pollution sources. Replacing hard revetments with single slopes, woodlands, etc., thereby restoring the ecological environment of the waterfront. According to the actual situation of water body location, meteorological climate, water body size, water level change, water quality characteristics, etc., ecological engineering is used to beautify the water landscape, construct artificial wetlands in the waters near the shore, and plant higher aquatic plants (to prevent invasion of alien species, disable large Poly grass, big drift, etc.). The landscape water ecosystem in the park should be maintained annually and the plants should be maintained regularly. (3) Biodiversity protection measures The vegetation area of the park has many types and distinctive features, and it has high ecological value and ornamental value. It is necessary to strictly implement relevant national policies and measures to maintain the state of the park vegetation ecosystem and protect it from vandalism. In the vegetation system in the park, special protection measures should be taken for rare species, such as numbering, archiving, capacity protection, regular inspection, and timely maintenance. Prevent and control vegetation pests and diseases in the park to protect vegetation from pests and diseases. We will implement the principle of “ prevention first, comprehensive management ” and adhere to the principle of taking biological control as the mainstay and supplementing chemical control. Establish predictive and forecasting, quarantine inspection, prevention and control organizations, improve forestry, update technical level, and enhance the immunity and self-harm of vegetation itself. Protect and cultivate natural enemies of forest pests and diseases, mainly based on the original species in the region or nearby areas. The natural enemies to be introduced must be tested and demonstrated to prevent the invasion of alien species. The landscape goal of park construction is to achieve species diversity and landscape diversity. The measures for the construction of the ecological diversity system of this project are mainly: Under the premise of adapting to suitable trees, the seedlings are ensured to be excellent and

90

robust, and the rational allocation of tree species to ensure the efficiency and stability of the park ecological plant group. The tree species can be rationally arranged in the green landscape area to achieve three-dimensional development. There are both tall tree species and more grassland plants. Reasonable implementation of tending management measures during the growth of trees, including weeding, artificial pruning, pest control. According to the Notice on Strengthening the Prevention and Control of Invasive Invasive Species (Huanfa [ 2003 ] No. 6), "Notice on the Issuance of the First List of Invasive Alien Species in China" (Huanfa [ 2003 ] No. 11), "On the Issuance of China" For the second batch of notifications on the list of invasive alien species (Huanfa [2010 ] No. 4), in order to protect local biodiversity, the species specified in the above documents shall not be introduced in the construction of this project. 7. 2 Eco-environmental impact assessment of the reed project of Luxi River Luxi River Improvement Project area where the proposed project to the main river ecosystems, according to affect the characteristics of the regional ecological environment and the characteristics of the project, the environmental impact from construction of major ecological forecasting and analysis service period were made in two stages, the focus of analysis Ecological environment impact during construction period. 7.2.1 Ecological environmental impact assessment during construction period (1) Impact on aquatic ecology during construction period The construction of the Luxi River channel improvement project will have a greater impact on the river environment. After the sediment has been dug, the riverbed environment from the natural succession will change, and the original alternating shade will become flat. Environmental changes caused by waterway dredging projects will directly affect the survival, behavior, reproduction and distribution of aquatic organisms, causing the death of some aquatic organisms, the decline of biomass and net production, the reduction of biodiversity, aerobic plankton, fish, and bottom. Zoos will die as a result of environmental degradation, resulting in a series of changes in the entire aquatic ecosystem. These effects are basically unfavorable, but they are also reversible, and the impact time is short. After the construction is completed for a period of time, the damage caused by the construction of the aquatic ecosystem will be restored. 1 aquatic plant River dredging and remediation will change the current situation on both sides of the slope and change the living environment of the emergent plants. During the construction period, the water plants on both sides will disappear. The rectification of the Luxi River includes river dredging, and the river bottom environment will change. During the construction period, the submerged plants will disappear. According to the investigation of dredging after similar river courses, the water plants and floating plants can be recovered in a short period of time after dredging, while the recovery time of submerged plants is longer. In addition,

91

the restoration of submerged plants is related to the transparency of the water body. After the sediment dredging and sewage interception works, the water quality of the Luxi River will be better than the current water quality conditions, and the transparency is higher, which is conducive to the faster recovery of submerged plants. 2 benthic animals Most benthic animals live in the sediment for a long time. They are characterized by strong regionality and weak migration ability. They have sudden changes in the environment and usually have little or no ability to evade, and the excavation of large-scale sediments will cause various types of sediments. The habitat of benthic organisms is severely affected and most will die. However, according to data from the survey of benthic animals after river dredging, the benthic animals can recover to a certain extent after dredging, but the recovery process is slow. In addition, the longer the recovery time, the better the benthic will recover. Due to the poor benthic environment in Luxi River, the improvement of sediment environment and water quality and the removal of contaminated sediment will help the reconstruction of river aquatic environment and accelerate the recovery of benthic animals. 3 fish Changes in the nature of the riverbed can also cause changes in the conditions of fish spawning, which is not conducive to fish reproduction and has a certain impact on river fish. Due to the strong migration ability of fish, suitable habitats can be found in the surrounding rivers, and the fish affected by the project are common local fishes, and there are no rare and protected fish. Therefore, the adverse impact of construction on fish is small and temporary. All in all, due to the Luxi River, there is a certain degree of pollution of water bodies, many organisms are not suitable for growing in this environment, river original biomass and net production is not high, but these aquatic organisms are common river aquatic environment Species, unprotected or endangered species. Therefore, the loss of biomass and net production of aquatic communities during the construction period is not large, and the loss of biodiversity is not too great. (2) Impact on the terrestrial ecology during the construction period The impact of the construction of the Luxi River channel improvement project on the terrestrial ecological environment is mainly reflected in the construction period, the impact of the construction operation process and land occupation on land use, vegetation, soil erosion, etc., and the change of some original topography It destroys the existing vegetation and causes local exposure to the surface, which also destroys the original natural features and landscape, and brings the conditions of soil erosion to the rainy season. The Luxi River channel improvement project covers an area of 10 7013 m 2, and the project area has been planned as a land for logistics parks, resulting in no significant loss of vegetation ecological function. And because the project itself, including the landscaping

92

project, there is a loss of natural vegetation to compensate artificial vegetation after construction is completed, the original Luxi River on both sides of the exposed portion of the surface, there is the phenomenon of soil erosion, through artificial measures to further improve the coverage of vegetation. The spoil ground is a temporary land, which can be reused after the project is completed. The loss of ecological function caused by vegetation damage is limited to the construction period. In addition, the construction will carry out excavation and filling of earth and stone, and the exposed ground will cause a lot of dust in the dry season, which will have certain impact on the nearby vegetation. Dust will affect photosynthesis, leading to reduced crop yields and affecting tree growth. But with the end of construction, these adverse effects will gradually disappear. Although the construction period has a certain degree of impact on biomass, distribution pattern and biodiversity, the artificial planting of greening trees and shelter forests after the completion of the project can effectively compensate the impact of the project construction on the regional vegetation and compensate for the vegetation damage. Loss of ecological function, if the vegetation is reconstructed, the rationality and integrity of the vegetation structure can be considered. Pay attention to the combination of trees, shrubs and herbs, and use local tree species for greening construction, and plant various ornamental plants. Vegetation reconstructed on the land of the project will obtain a more complete community structure, more species, greater ecological and environmental benefits and environmental beautification benefits. (3) Analysis of soil erosion during construction period Soil erosion is the result of both natural and human factors. In the context of regional natural erosion, the main factors that may aggravate soil erosion in the project are reflected in two aspects: on the one hand, the construction has disturbed, destroyed the surface vegetation and farmland and other facilities with soil and water conservation functions, and changed the slope length and slope of the original slope. The surface runoff convergence process is changed to make the slope rock layer bare; at the same time, the disturbance and destruction cause the soil texture to change accordingly, resulting in a significant increase in the regional soil erosion modulus and aggravation of soil erosion in the region. On the other hand, earthwork excavation will produce a large amount of waste slag. Most of the waste slag stacking has not taken corresponding protective measures. During the construction period, it is washed away by heavy rain, resulting in a large loss of waste slag, resulting in a significant increase in the amount of new soil erosion. If no preventive measures are taken, it will accelerate the soil erosion in the construction area and bring huge losses, mainly in the following aspects: 1 Land damage leads to increased soil erosion, soil organic matter loss, soil structure damage, soil nitrogen, phosphorus, potassium organic nutrients and inorganic salt content

93

decrease, the number of animals, microorganisms and their derivatives in the soil is reduced, thus giving Later vegetation restoration and land remediation will increase the difficulty. 2 With the occurrence of soil erosion, the amount of suspended solids and other organic and inorganic pollutants entrained into the water by the surface runoff increased, which caused the water function of the waters to decline, which adversely affected the water environment of the regional water supply and water resources. The inconvenience caused by the lives of local residents. Soil erosion causes land productivity decline, water function decline, and ecological environment deterioration, which is not conducive to the sustainable economic development of the surrounding areas of the project construction area. ③ a lot of mud erosion caused by construction generated by the siltation of the river downstream, reducing the flood capacity of the river, flooding farmland may cause overflowing water will be pressed sand, aggravated term flood and drought disasters in the region where the mesh. Sediment entering the drainage system may cause blockage of the pipe network and poor drainage. In case of heavy rain, the road area is seriously water, which affects the normal life and traffic order of the citizens. (4) Impact on the landscape environment during the construction period The water quality of the upper reaches of the Luxi River is good, the water quality of the downstream river is poor, the pollution is serious, the garbage is often near the village water, and the water hyacinth grows in the local river section, which seriously affects the growth of other aquatic plants and the flood discharge capacity of the river. Because there is no unified planning and management, the value of river landscape entertainment is low. The negative impact of the project on the landscape and visual environment is mainly reflected in the construction period. A large number of excavation of construction sites, various types of construction machinery operations, construction waste slag, construction of building materials, etc., will have adverse effects on the landscape and visual environment. 7.2.2 Evaluation of ecological environment impact during service period (1) Analysis of river hydrological impact 1The influence of river hydrological situation and water flow pattern After the construction of the project, the hydrological situation in the region has a great change in factors such as water level, flow direction and flow rate, but this change can improve the drainage and storage capacity of the entire river network. Before the implementation of the project, some river by arable land encroachment, the river was narrow beam, some of the design flood level reaches flood level higher than after treatment, once every case 2 0 -year flood flow, river flood insecurity, governance area There is drowning effect. The flood control project on the natural flood sections were cut and fill, expand, making the Luxi River water flow, river management design flood level below the top elevation of the shore. The flood control and flood control capacity of the river channel has been greatly improved. The Luxi River flood control dike project and flood discharge

94

irrigation and drainage canal are designed according to the flood standard of 20 years. The Unicom Canal is designed according to the reference flow. The design flow rate of the fourth and fifth grade concrete overflow dam is 348.09m 3 /s, and the check flow rate is 444.77m 3 /s. The energy-saving and anti-shock buildings are set according to the 10- year flood standard. The natural inflow water of Luxi River has an obvious alternating evolution of the abundance and dry years. The main factors of the runoff change are the conditions of the upstream underlying surface, the climate and the spatial and temporal distribution of regional water resources. The water pumping station uses the pumping station to replenish water. Ensure that the river has sufficient fluidity, the water depth during the dry season is not less than 0.3m, and the hydrodynamic conditions are improved. 2 analysis of the impact of flood prevention and rescue According to the "Flood Prevention Law", after the completion of the project, it is strictly forbidden to stack obstacles that impede flooding and flood-fighting traffic within the river section. The construction of this project considers a 4 m wide rescue road in the design of the two sides of the river bank, and can ensure the smooth transportation of anti-flood and rescue materials during the emergency flood control period. After the completion of the project, the river channel will be widened, the over-current capacity will be too large, the flood control capacity will be improved, the flood control and flood control capacity will be satisfied, and the bank slope will be stable, which is beneficial to flood control and rescue. 3 analysis of the impact of flood safety The rectification of the project has widened the river course, and the hydrological situation and the shape of the water flow caused by the construction of the project are beneficial. This river improvement project flood control standard 2 0 -year return, waterlogging control for the same period of rainwater P = 5%, is the main controlling flooding in the project, had no effect on flood safety of the river. 4 predictions of river stability The project is mainly based on river embankment reinforcement, the flow rate is smaller than natural conditions, and the flow direction is more natural. The river channel is constructed by riverbank slope protection project, and it is designed with anti-shock measures. The erosion is not large and the river is stable. 5 analysis of the impact of existing flood control projects, etc. Downstream of the project area, there are already built rubber dams of Grade II, II and III of Luxi River. This project is also an integral part of the flood control and flood control of Luxi River and has no impact on existing flood control projects. (2) Analysis of ecological and landscape environmental impacts 1 analysis of the impact of terrestrial ecology Before the implementation of the project, the terrestrial ecosystem types in the assessment

95

area were mainly weeds, shrubs and some crops distributed on both sides of the engineering section. After the implementation of the project, in order to meet the requirements of ecology and landscape, the slope protection design abandons the form of hard slope protection that cannot be greened and can not provide habitat for the organism. The ecological slope protection that can be greened, seepage and drainage is beneficial to plant growth. It is conducive to the survival and development of terrestrial ecosystems on both sides of the engineering section. At the same time, combined with the functional factors of different regions to carry out different plant configurations on the shore slope water, it can compensate the original vegetation damaged by the engineering construction, while protecting the river channel, it is conducive to the improvement of the ecological environment along the line. After the implementation of this project, the green area of the river, the embankment, and the top of the embankment can be significantly increased. The supporting greening and beautification project provides people with a friendly and pleasant leisure space and green ecological space to achieve the harmonious development of people and nature. Status of the river are generally artificial vegetation to grassland -based, can be artificial grass through reconstruction and rehabilitation, afforestation and other measures in the construction process, to avoid damage to the existing vegetation, to preserve must be retained. In addition, after the landfill and silt dumping site are filled, through greening, the local land ecological environment quality can be greatly compensated, and the local landscape can be greatly improved. The reconstructed riverbank ecological environment will be better than the current situation. Construction of the project will make part of the ground hardening, changing the natural properties of permeable cushion under vegetation and soil, a certain area of ground sclerosis affects the ground water permeability, blocking rain to replenish groundwater, increased evaporation of surface water, not Conducive to the survival of native plants and animals. It is recommended that the project use first-class floor tiles, curbstones, sapphire stones and other paving materials. All materials must have a factory certificate, and use permeable bricks in parking lots, pavements, etc. to reduce The impact of ground water permeability on the ground hardening of the project has little effect on the regional terrestrial ecology. 2 impact on aquatic ecological environment After the dredging project, sewage interception project and water replenishment project, the water flow speed will be accelerated and the dissolved oxygen content in the water will be increased, which will improve the river water quality and benefit the survival and reproduction of various aquatic organisms. At the same time, the river channel is rehabilitated with a natural river section. The shape of the rectified river section is diversified, maintaining the deep pool and shoal of the river, and the plane width is different, which also creates a good habitat for underwater animals. Optimization of the living environment will facilitate the growth and reproduction of aquatic organisms.

96

After the project is completed, the growth and reproduction rate of benthic organisms may increase due to the excavation of sludge at the bottom of the river. The improvement of the quality of the sediment will also be beneficial to the hatching of fish eggs and the growth of fry. The concentration of pollutants in water is reduced, and the increase in oxygen content is beneficial to the growth of various aquatic organisms. As the water quality becomes clear and the light transmission depth becomes larger, it will be beneficial to the growth of photosynthetic plankton, thereby driving the productivity of the entire ecosystem. The increase in various plankton will make the fish and shrimps that feed on these creatures, as well as the large fish that feed on small fish and shrimp, get a more adequate food supply. Thus, upon completion Luxi River, biomass and net production within aquatic communities will have improved greatly. As the water quality becomes better, the habitats of various organisms will improve. Some plankton (such as brown algae, clock worms, etc.) that are not suitable for living in the original environment can grow and breed in the river. Some non-soil-resistant fish can also After moving to this settlement, the improvement of the quality of the sediment also allowed some benthic organisms with low stain resistance, such as snails and mites, to reproduce. The migration of various organisms has increased the species diversity of the Luxi River.. With the improvement of biodiversity, the species structure of the aquatic ecosystem in the river will be more perfect, the chain-breaking link of the food chain will be restored, and the food network will be complicated. The restoration of habitat heterogeneity also completes the horizontal and vertical structure of the ecosystem. As a result, the entire aquatic ecosystem is more mature, and its quality, stability and service functions will be improved, which will help prevent or slow down the deterioration of the ecological environment. Overall, the completion of the project will improve the aquatic ecosystem of the Luxi River, increase biomass and net production, increase biodiversity and heterogeneity, and complete the ecosystem structure. 3 impact on the landscape At present, the domestic sewage and a small amount of industrial wastewater in the Luxi River are directly discharged nearby, and the garbage in the river is scattered. This situation causes serious pollution to the water body, causing serious water environmental problems, and some river sections are occupied by farmland and houses. Dirty, narrow rivers and poor landscape conditions. The implementation of the river comprehensive improvement project will clean up the existing scattered river channels, and the pollutants that are directly discharged into the Luxi River will be intercepted by the sewage pipeline and sent to the Qianfeng Wastewater Treatment Plant for treatment. The project riverbank slope protection project has abandoned several traditional slope protection types such as slurry or dry block rock slope protection, cast-in-place concrete slope protection, precast concrete block slope protection, geomembrane bag concrete slope

97

protection and rope hinged concrete plate slope protection. in the form of project cost not only relatively high, and the river itself only focus on basic functions such as flood control, drainage, etc., impact on the environment, ecology almost not taken into account, the negative impact on the environment and ecology of large, hard revetment structure isolated The contact between organisms and microorganisms and the earth has caused the organisms and microorganisms in the river to lose the environment on which they depend, and it is difficult to survive and destroy the overall balance of the river ecosystem. The way to slope protection project engineering measures and plant measures combine to maintain the river's ecological functions of the original design for the grass slope above flood level or planting low shrubs, design flood level the following planting aquatic plants can beautify the landscape, back to return The natural ecological landscape of the river, as well as the ecological revetment method such as turf slope protection, can promote the exchange of surface water and groundwater, make up the flood, adjust the water level, restore the growth of animals and plants in the river, and use the functions of animals and plants to purify the water body. It can stabilize the riverbed, improve the ecology and beautify the environment, avoid the negative effects brought by concrete engineering, and effectively prevent flood erosion, so that the dam surface water flow can be stably downstream and extravasated in the sponge body without dam. Body particles, which have a good anti-seepage effect. In addition, according to relevant literatures, river ecological slope protection has a delay effect on surface runoff, which can reduce the total runoff discharge, and the chemical, physical and biological reactions of runoff in the process of infiltration into the lower layer of soil, causing sedimentation in runoff. Things and other pollutants are cut. It has a good intercepting effect on suspended solids and nutrients in surface runoff. Responsible for river training works in greening the ecological environment an important function, Luxi River training works in conjunction with associated green space system planning as well as the surrounding land development and construction projects on the basis of the distribution of the entire greening projects include emergency road within river bank slope greening and road rescue Other green areas such as 20 - 25 m natural ecological zone, public leisure activity zone, and citizen fitness and entertainment zone. According to the characteristics of different functional areas, reasonable plant configuration, combining plant selection with ecological effects, is the basic means to maximize the ecological benefits of greening. River bank slope greening in the protection and utilization of the current river vegetation and does not affect the river flooding and drainage, control the river slope and coastal areas of soil erosion, to maintain the stability of the slope, follow the natural ecological principles, the entire riverbank green land parallel to the reed The Xihe River distributes vegetation types such as floodplain wetlands, riverside wild flowers and vines, riverbank bamboo forests and riverbanks. In the green design of the 20 - 25 m green belt, make full use of the current landscape pattern, and try to retain and

98

utilize the current native plants such as bamboo and select species that are compatible with the local climate and soil to construct green with local characteristics and urban personality. landscape. This kind of greening will not cause waste of natural resources. In terms of greening methods, the EIA proposes the following suggestions: 1) Try to use plants with large leaf area, wide leaves and high photosynthetic efficiency to improve the photosynthetic efficiency of the community, create a suitable microclimate environment, and improve the connection between the public and the natural environment; 2) Selecting pollution-tolerant and anti-pollution plants can exert the adsorption and assimilation of pollutants by green space, reduce urban pollution and promote urban ecological balance; 3) Reuse and reuse the soil adaptations such as green land litter and green manure to form communities The benign circulation mechanism of self-fertilization reduces the use of non-renewable resources such as fertilization, weeding and pruning, and reduces the cost of green land construction and maintenance. The landscape construction of the Luxi River is based on the overall planning of the Qianfeng District in the region. The ecological conditions of the Luxi River and the natural resources are organically combined to give full play to the green plants and bamboo resources on both sides of the river. The Lord respects nature and advocates ecology, which fully reflects the design principle of nature. The layout of the landscape layout fully considers the division of the functional areas along the coast and the distribution of development and construction projects of the surrounding land. Through the implementation of the landscape project, the greening of the two sides of the river can not only improve the ability of urban flood control and drainage, but also improve the beautiful scenery on both sides of the river. The ecological landscape makes the water network and the road network space an organic combination, which greatly enhances the landscape viewing of the Luxi River and its two banks. In addition, the cleanliness of the river and the maintenance of the surrounding environment will also affect the landscape environment. The poor management may bring negative effects. 7.2.3 Ecological protection measures (1) Strengthening the mission of environmental protection for construction workers During the construction period, the terrain and landform will be destroyed, the vegetation will be destroyed, and the farmland will be invaded, resulting in some surface exposure, changing the soil structure, and changing the ecological structure and function of the area along the line, thus affecting the stability of the ecosystem. Therefore, it is necessary to strengthen the environmental awareness of the construction workers, and prohibit construction workers from destroying vegetation outside the design site. (2) Protecting the upper surface and vegetation The construction unit shall, during the pre-construction period, strip, temporarily store and

99

protect the 0 to 20 cm fertile soil layer according to the design documents, and transplant the original trees for subsequent land reclamation or river bank slopes. Self-greening between the outer line of the rescue road and the landscape control line. Engineering supervision personnel are required to strengthen the supervision work of this operation, because this work is one of the important factors to improve the survival rate of planting trees and grasses within the scope of protection of land use and greening of projects. (3) Soil and earth loss will be generated during the construction and construction process, and soil erosion will occur during the drying and stacking process of the sediment. In case of rain, water and soil loss will occur. To prevent serious soil erosion, take Establish a complex retaining wall combining engineering and vegetation, excavate drainage ditch or intercepting ditch, carry out greening and other measures to prevent rainwater from eroding the soil, prevent soil spillage, and strengthen the spoil (slag) in the process of leveling the construction site. Management, construction and construction should be arranged in the dry season as much as possible to avoid the occurrence of soil erosion, so as to minimize the potential impact on the ecological environment. (4) Aquatic ecological protection measures 1 The project construction causes the death of aquatic organisms, which will cause damage to the aquatic ecosystem. To accelerate the reconstruction of the damaged ecosystem, various aquatic organisms (such as various fish and shrimps, submerged plants, river otters, etc.) can be placed in the river. But the quantity and proportion of delivery must be properly controlled. 2 Reconstruction of aquatic ecosystems should pay attention to the reasonable arrangement of biological species, and should be placed in freshwater aquatic organisms common in the region. 3 Pay attention to restoring the integrity of the structure and composition of aquatic ecosystems, optimize the community structure, and arrange stocking according to the habitat and living rules of various aquatic organisms. According to the predation relationship between various aquatic organisms, a complete and complex biological network should be constructed, from the lowest trophic level of phytoplankton and aquatic plants to the higher- nutrition carnivorous fish. The habitats of different organisms are also different. According to different habitats, different aquatic communities can be constructed separately. For example, large submerged algae, river otters, snails, loach, scutellaria, etc. can be placed at the bottom of the river. Other depths can also be The living rules of living organisms construct aquatic communities. Increasing the complexity and integrity of species and spatial structures will help to improve the stability of aquatic ecosystems, thereby preventing or mitigating the adverse effects of deterioration of the external environment. 4 Strengthen the management of the river environment after the completion of the project. Untreated wastewater should not be discharged into rivers to prevent eutrophication

100

of aquatic organisms and water bodies. At the same time, it is necessary to regularly salvage surface waste and remove contaminated sediment to reduce the internal pollution of the river itself. (5) Terrestrial ecological protection measures 1 After the completion of the construction, the surface of the waste slag yard shall be leveled and topsoil covered, and vegetation restoration measures shall be taken according to the basic laws of vegetation ecological succession, and vegetation restoration measures or reclamation measures shall be taken on the exposed surface caused by the spoil ground. Moreover, the temporary construction site and the construction temporary road should be restored to their original condition, and the renter should organize the restoration or vegetation restoration. 2 The construction of the project will reduce the vegetation area and plant production of the construction site, resulting in a decrease in oxygen supply and carbon dioxide absorption, thereby reducing the ecological service function of the ecosystem where the project is located. In the later stage of construction and early stage of operation, the greening project within the scope of land acquisition should be implemented according to the greening and beautification design of the project. Local governments and project builders should strengthen the construction of riverside and bank slope vegetation and increase the area of green space to compensate for the loss of ecosystem functions caused by the completion of the project, while maintaining coordination with the urban landscape to achieve better landscape effects. 3 Green space construction should pay attention to the combination of trees, shrubs and herbs to form a multi-layered three-dimensional structure, a green space system with good ecological functions, and use a variety of plants for greening, pay attention to the ecological relationship between different plants, and more Indigenous species are greened to maintain regional biodiversity and ecosystem stability.

Environmental impact analysis Table (8) 8.1 Environmental impact factors during construction period 8.1.1 Analysis of atmospheric environment impact during construction period In the construction work, the main sources of air pollution are: site cleaning, foundation excavation, dust from the transportation vehicles and construction machinery, and loading, unloading and transportation of construction materials (cement, lime, sand and gravel). The pushing process and the excavation and excavation pile up and transport process cause lifting and spilling; the exhaust gas discharged by various construction machinery and transportation vehicles; a small amount of foul odor generated in river bed dredging. The danger of dust pollution cannot be ignored. The dust floating in the air is inhaled by the construction workers and surrounding residents, which not only causes various respiratory diseases, but also contains a large number of pathogenic bacteria in the dust, which infects various diseases and seriously affects the health of the construction workers and surrounding residents. In addition, dust flutters, reducing visibility and easily causing traffic accidents. Dust falls on the branches of buildings and trees, affecting the landscape. (1) Impact of construction dust on the surrounding environment Most of the Luxi River channel improvement project is the existing riverbed, the soil is humid, and the dust generated by the excavation and bulldozing process is relatively small. According to the similar engineering analogy, when adopting better dustproof measures, the influence range of dust emission is basically controlled within 150m, not more than 1.0mg/m 3 within 150m, and the TSP concentration contribution of 200m has been reduced to 0.39mg/m 3. If the dust control measures taken are not effective, within 250m will be subject to greater impact of construction dust, the concentration contribution of up to 250m 1.26mg / m 3, other than 350m can be reduced to 0.69mg / m 3 or less, can be reduced to beyond 450m 0.44 mg/m 3 or less. It can be seen that if dust-proof measures are not taken, the dust will be seriously affected by construction dust within 450m, and the TSPconcentration of units and residential quarters around the construction site will greatly exceed the standard. Construction area surrounding the distribution of major air andenvironment sensitive points along the line of view, from the nearest residential area to the surrounding XIEJIAWAN park construction planning is about 3 0m, when the project construction period should be based on residential construction progress In the case, it is necessary to strengthen the control measures for excavation of dust to reduce the impact on the surrounding residents; the area of the Luxi River channel improvement project has been planned as a logistics park, but there are still a small number of sensitive points such as households and schools, and the construction process should pay attention to Covering measures around the sensitive points to avoid the impact of construction dust on sensitive targets. (3) Impact of river dredging on the surrounding environment The lower reaches of the Luxi River currently have poor water quality and are polluted rivers. The content of organic matter, nitrogen and phosphorus in the surface sediment is high, and odorous gases

102

such as hydrogen sulfide and ammonia are formed under anaerobic conditions. According to the analogy analysis, there will be obvious odor on the bank of the river channel during the dredging process of the river. It will reach the level 2 intensity outside 30m, with slight odor, lower than the limit of odor intensity (2.5-3.5);substantially odor than 80m. According to the on-site investigation, the distance between the classroom area of the Qianfeng Elementary School and the river construction area isabout 10 m, which is less affected by bad odor, and the impact is temporary, and it disappears with the end of the construction period. In order to avoid the impact of the odor generated in the heavily polluted rivers on the surrounding environment, the dredging operation can be strengthened to ensure the stability of the dredging equipment, and the odor generation during dredging can be reduced. If it is found that some of the sparse spots have obvious odor generation, the construction of baffles on both sides of the strait shall be adopted to strengthen the protection of construction workers and minimize the affected population. In addition, due to the dredging operation using dry excavation and dredging, certain dust will be generated during the construction process, which will have certain TSP andPM10 effects on the surrounding air. (4) Impact of waste silt field on ambient air The organic matter content in the riverbed silt is high. When the sediment is in the anaerobic state, a small amount of odorous gases such as H2S and NH3 are emitted. The sludge will remove some pollutants during the natural desiccation and dehydration process in the mud disposal area set up in the river landscape area. Due to the good ventilation state during the drying process, the sediment is less anaerobic and greatly reduces the odor pollutants. The production. According to the analogy analysis, it is basically odorless outside of 80m, and there is no environmental sensitive point within 100m around the mud discharge field, so the odor has little effect on the surrounding air. (5) Impact of vehicle transportation on the surrounding environment The project construction vehicles sediment materials during transport, earthwork grain (powder) form of spilled material and construction vehicles moving at the construction site will produce some dust, according to the results of research analogy, wind speed under normal weather conditions, transportation During the process, the dust concentration decreases rapidly with the increase of distance. Generally, it can meet the secondary standard of ambient air quality standard at 150m, and the dust on the construction road has obvious local pollution characteristics. The project implements watering and dust suppression measures on the road surface of the vehicle. Sprinkling water for 4 to 5 times a day can reduce the dust emission by 70 %. In addition, the sediment and earth transportation are managed according to the regulations of loose mud transportation. The wheels are cleaned when the transportation vehicles enter and exit, and the car boxes are sealed and sealed, which can effectively reduce the generation of field dust. The selection of construction vehicle transportation routes should avoid sensitive points such as densely populated areas, schools and hospitals, and have little impact on the ambient air along the route. The NO2 and CO exhaust gases discharged from the construction vehicles are relatively small, so

103

they do not have a large impact on the surrounding environment. In summary, the ambient air pollution during the construction period has the characteristics of large variation with time, near drift distance, small influence distance and range, and its impact is limited to the construction period and stops with the end of the construction period. The project is to strengthen the management of dust emission sources. The stockyard should be considered as far as possible in the place where the wind direction and distance are far from the residential area. When the material transport vehicles adopt dust suppression and dust reduction measures such as watering, dust reduction and cap sealing, The impact on the ambient air during construction is minimized. 8.1.2 Environmental Impact Analysis of Surface Water during Construction Period The wastewater generated during the construction of the project mainly includes the domestic sewage of the construction workers and the wastewater generated by the construction itself, mainly including pollutants such as COD, SS, animal and vegetable oil, BOD 5 and petroleum. Before the sewage treatment, the concentration of COD is 350mg/L andSS300mg/L. If the wastewater is directly discharged, it will produce odor and breed mosquitoes and flies, which will adversely affect the environment. (1) Domestic sewage Due to the large construction area and relatively scattered construction sites, the domestic sewage produced by the construction workers of the Luxi River channel improvementproject is planned to be near the nearby sanitation facilities and not discharged separately; the sewage from the construction camp of the Xiejiawan Park construction project is collected. It is transported to the Qianfeng District Sewage Treatment Plant by tanker to discharge the standard. Therefore, a small amount of domestic sewage generated during the construction period has little effect on surface water. (2) Construction wastewater The construction site includes construction and maintenance, which will produce wastewater. The pollutants in the wastewater are mainly SS and contain a small amount of oil. It is recommended to set up a sedimentation tank, and the wastewater will be recycled after being separated by oil separation and sedimentation. Without access to surface water, the environment is acceptable. (3) Dredging wastewater The river channel extension of this project adopts dry excavation construction, which is relatively dredging by wet method, and the disturbance of the sediment on the river bottom is relatively small, and the concentration of suspended matter is small. River Dredging Project-based mechanical excavation, construction land to create conditions need to implement diversion project, by way of diversion classification, the original river diversion scheme can be divided into different river diversion and diversion into two categories, this project uses With the river diversion, the adverse effects on the surface water environment are small compared to the diversion of different rivers. The suspension construction dredging regional water content of the body increases, the influence of water quality on the river Luxi obvious, but is suspended sediment particulate substance, as it is while water movement in the river sediment, and finally deposition in the river This characteristic determines that

104

its influence range and influence time are limited, and the influence of the sediment diffusion caused by dredging will disappear with the end of construction. According to similar engineering experience, the impact on theLuxi River can be effectively mitigated by setting up cofferdams in the dredging section. (4) Analysis of groundwater environmental impact The project is a river improvement project and a municipal park construction project. The construction involves strata including the Quaternary Holocene landfill (Q 4 me), the Quaternary Holocene alluvial deposit (Q 4 al+pl) and the Jurassic system. The Zhongxuan Shaximiao Formation (J 2 s) involves stratigraphic lithology of silty clay and mudstone. The Quaternary New Territory Filled Soil (Q 4 me) low liquid limit clay layer and the Quaternary Holocene alluvial deposit (Q 4 al+pl) have poor water-rich soil layer and the groundwater type is loose rock pore water. It is mainly recharged by atmospheric precipitation. The groundwater volume is limited by atmospheric precipitation. The amount of water is usually small and the supply and distribution are uneven. The roadbed construction of the proposed project will directly damage the Quaternary strata, which will directly affect the recharge and transportation of Quaternary groundwater on both sides of the road along the route. However, since the groundwater supply source of the Quaternary stratum is atmospheric precipitation, the highway is a linear project with a relatively small area, which generally has a relatively small impact on the groundwater recharge of the formation, and has no obvious impact on the planned new urban area. Overall, the groundwater sensitivity of the project area is low, and the groundwater resources are not abundant. The impact on the destruction and recharge of groundwater resources during the project construction period is generally small. 8.1.3 Analysis of acoustic environment impact during construction period The noise of this project mainly comes from the noise of transportation vehicles and construction facilities. During the construction process, the noise of non-mechanical operation is generally 65 decibels, and the noise of transportation vehicles and construction facilities is generally around 85 decibels. These construction noises are within 10 mradius of the construction site, and most of them are exceeding the standard. A small part of the phenomenon exceeds the standard within 30 m. During the construction period, the number of vehicles passing by the road will increase, which will cause the traffic noise value to rise. Therefore, it is necessary to minimize the noise impact during the construction period, especially at night construction, and measures must be taken to strictly control it. The prediction of noise sources during construction is usually considered a point source prediction calculation. According to the point source attenuation mode, the noise value of the different distance sensitive areas from the source can be estimated. The prediction mode is as follows:

L Aeq  L po  20 lg( r / r0 )

Where: L Aeq is the construction noise from the sound source r m [dB(A)], L po is the sound level [dB(A)] at the sound source r 0 m,

105

A attenuation constant, dB(A). r is an (m) the distance from the sound source, r 0 to (m) from the prediction result from the sound source at different distances from the construction machine in Table 8.1 --1. Table 8.1-1 - Various construction equipment and noise source strength at different distances (dB) Mechanical Sound source Noise prediction value model characteristics 5m 10m 20m 40m 50m 100m 150m Unstable Wheel loaders 90 84 78 72 70 64 60 source Flow instability bulldozer 87 81 75 69 67 61 57 source hydraulic Unstable 85 79 73 67 65 59 55 excavator source Fixed stable generator 98 92 86 80 78 72 68 source Fixed stable Water pump 84 78 72 66 64 58 54 source Wind hammer Unstable 98 92 86 80 78 72 68 and rock drill source 20, 40 tons dump Flow instability 97 91 85 79 77 71 67 truck source Flow instability truck 91 85 79 73 71 65 61 source Flow instability Forklift 95 89 83 77 75 69 65 source Flow instability Forklift 82 76 70 64 62 56 52 source Flow instability Mobile crane 91 85 79 73 71 65 61 source Construction noise characteristics and hazards: Although the equipment noise is generated during the construction period, due to its impact, long duration and strong vibration, it is very harmful to the environment, especially the construction workers and residents. The equipment invested in different construction stages has different effects on environmental noise. It is mainly the trench excavation and filling of pipelines, leveling the land, mainly based on the noise of various transportation vehicles. The operation of construction equipment is dispersive, the noise is fluidity and instability, and the impact on the surrounding environment is not obvious. Construction noise is largely determined by the distance between the construction site and the above sensitive points and the construction period. The closer the distance is, the greater the impact on construction at night. The noise impact during the construction period is short-lived. Once the construction activity is over, the construction noise will also end. As can be seen from the table, daytime construction noise evaluation criteria drop to about 70dB from the noise source 150 m, the range of m visible inside the noise impact on the environment in the

106

periphery of the construction site from 20 to 150. After field surveys, there are no sensitive points such as residents, schools and government units within 150 m of the project site. Therefore, the impact of noise on the outside world during construction period is small. However, the project should still be civilized during construction, and try to control the generation and spread of noise. Construction operators and on-site construction personnel shall control working hours according to labor hygiene standards and do their own protection work, such as wearing earplugs and helmets. 8.1.4 Environmental Impact Analysis of Solid Waste during Construction Period (1) Sediment produced by dredging Luxi River Improvement project of solid waste is the dredging of the main pollutants. In the treatment of river sediments, it is necessary to consider the comprehensive utilization of river sediments, and must avoid harm to the environment and the health of the population. According to Chongqing Suoao Detection Technology Co., Ltd. of river sediment sampling monitoring, the monitoring factors are met "Soil Environmental Quality - soil contamination risk control standards of agricultural land (Trial)" (GB15618-2018) requirements of risk-based screening values, indicating that the The sediment is suitable for general farmland, vegetable land, tea garden, orchard, pasture and other soils. The soil quality basically does not cause harm and pollution to plants and the environment. Due to the dry dredging, the silt has a low moisture content. After being dried for two or three months, it can be considered for gardening, flowering and greening. According to the relevant information, the river bottom sediment is very feasible for gardening. On the one hand, it can improve the soil quality of the greening land and increase the fertility. On the other hand, the pollutants in the sediment do not enter the human food chain, eliminating the risk of population health. At the same time, the inhibitory effect of pollutants on the growth of plants is not obvious. In accordance with the principle of minimizing the occupation of cultivated land, minimizing the row spacing, relatively concentrated, and reducing the amount of cofferdam filling works, the project dumping site is located in the depression area of the river remediation landscape area, close to the river remediation construction site, reducing the farmland of farmland. Occupied. Before the sediment is piled up, the bottom of the clay is compacted and a cofferdam is built around it. At the same time, the soil and water conservation measures are implemented for the waste silt yard, including engineering measures, plant measures, land remediation measures and temporary measures. Drainage channels and sedimentation fields are set on the top surface, slope surface and slope of the abandoned silt field. During the process of slag disposal, the layers are compacted and compacted, and humus soil is paved to facilitate greening. (2) Backfill earthwork In order to save the project cost, and in order to reduce the discharge of spoil gravel, the excavation earthwork of the project should be backfilled as much as possible.According to the special characteristics of each building and the corresponding construction period, the earthwork excavation of Xiejiawan and the earthwork filling, sewage interception project of the Luxi River channel and the

107

filling of the earthwork of the water supply project, the temporary construction road and the filling of the temporary cofferdam Try to use the excavated earth material backfill of the corresponding bank. Most of the remaining spoil is backfilled in the depressions that need to be filled in thelandscape greening project. The stripped topsoil is used for greening in the area. All the backfilled earthwork is excavated, and the utilization rate of earth and stone is as high as 100%. (3) Temporary topsoil area In order to protect the valuable topsoil resources, the topsoil must be stripped before construction, and then separated and placed in the topsoil storage area for protection, so that the site can be used for vegetation restoration after the construction. The topsoil temporary dumping area is also mainly located in the low-lying area of the landscape lighting area. The topsoil must be protected by the soil bagging retaining wall. The source of the soil material is stripped topsoil, and the temporary drainage soil ditch is excavated around the dumping area at the corner of the drainage ditch. Or arrange earthen grit chambers every 50-100m. In the rainy season or windy weather, the dust is temporarily covered on the topsoil. Soil and water loss can be effectively controlled during the construction process, which has little impact on the environment. (4) Construction waste The construction waste generated during the construction process is mainly used for demolition and construction of abandoned rotors, pavement fragments, waste wood materials, steel bars, used packaging paper, plastics and other construction waste, which can be included in the municipal solid waste treatment system, among which waste wood The template, broken steel bars, used wrapping paper can be recycled, and the rest can be sent to the construction waste landfill designated by the front-end area. After safe disposal, it has little impact on the environment. (5) Domestic garbage In the construction area, there are many complicated components such as organic matter in the domestic garbage. If it is not cleaned up in time, the organic matter in the garbage will deteriorate and rot, causing foul odor, polluting the air, attracting and breeding flies, breeding mice, and the pathogenic microorganisms in the garbage will be washed with the rain. The pollution of water quality will also pollute the atmosphere with the dust, causing disease transmission and epidemics, especially intestinal infectious diseases. In order to prevent the harm of domestic garbage to soil, water environment, landscape and population health, prevent garbage from dumping into the river at will, the domestic garbage should be bagged during the construction process, and collected and transported to the Guang'an Municipal Domestic Waste Landfill for disposal. The impact on the environment is small. 8.1.5 Analysis of the impact of the construction period on the social environment (1) The impact of construction on the social economy The construction of the project will drive the social and economic development of the construction area. The concrete manifestation is that the construction requires a large amount of construction materials such as cement, sand and stone, lead wire mesh, etc., which will promote the development

108

of local construction, transportation and other related industries. With the development of the project, it will promote the production and sales of local meat, vegetables and other non-staple foods, and will also promote the prosperity and development of the tertiary industry such as local service industry, culture and entertainment, and create employment opportunities, which will not only help to invigorate the local economy. And it will increase the economic income of the masses and improve the quality of life of the local people. The project construction will also improve the local infrastructure conditions such as transportation, communication and electric power, and promote the development of local tourism resources and tourism on the health and safety of the population. (2) Analysis of population safety and health impact during construction period The construction process, there may be some foreign workers to enter, because the quality of this part of the staff of ginseng difference is not surprising, may cause some inconvenience to the security perimeter within a certain time, so to strengthen security management during construction of the building, for the relevant local Departmental assistance. A large number of construction workers entered the work area, causing a sharp increase in the population density of the work area. At the same time, due to the relatively poor sanitary conditions of the construction site and the high labor intensity, it provides a means of transmission for various infectious diseases. The main affected population is the construction workers, which may also have a certain impact on the nearby population. Wastewater, various construction wastes and garbage in the daily life of workers during construction will cause various germs to germinate and spread diseases. The dust generated during construction will enter the human body with the breathing of the workers. Excessive retention will endanger human health. The noise generated by various machines during the construction process is excessive, which may cause harm to the construction personnel. Construction machinery has certain dangers during operation. It must be operated strictly in accordance with the operating specifications during construction. It is strictly forbidden to operate illegally or operate the machinery after drinking. The dredging process exposes the sediment to the air, and there is odor. At the same time, the sediment is easy to breed flies and mosquitoes, which easily leads to the onset and prevalence of insect-borne diseases such as malaria. Therefore, it is necessary to avoid direct pollution of the sediment by construction workers. Take protective measures to set up baffles on both sides of the heavily polluted river section to reduce the amount of odor that is dredged and directly affect the population. At the same time, it is necessary to sterilize the disinfectant on the surface of the sediment. Therefore, the construction unit must pay close attention to the adverse effects of the construction on the health of the construction workers and nearby residents, and take necessary precautions to prevent the spread and prevalence of the disease. In addition, since the activities during the construction period are temporary on the construction site, the harm to human health is also staged, and the damage will disappear after the construction. (3) Impact on traffic during construction period According to the same type of project engineering investigation, the pipe network construction has

109

the greatest impact on traffic, and the backfill soil, pipelines and building materials accumulated during the construction will inevitably occupy the sidewalk and bicycle lane. Pipeline construction generally has a slotting method and a pipe jacking method, which will have certain impact on traffic. When the pipeline crosses the road, although the pipe jacking construction without damage to the road surface can be taken, the bearing pressure of the road will decrease at this time, and the traffic of the truck must be prohibited in a short time, which will affect the urban traffic. It is estimated that when the pipe network crosses each road, it needs to be constructed for about 20 days, so the impact on the road lasts for about 20 days. Although the transportation volume of raw materials is large, it has little impact on urban traffic because it is not concentrated. The earth and stone in the construction area of the project can achieve regional balance without waste slag transportation, and the project construction has little impact on urban traffic. 8.2 Environmental Impact Analysis during Operation Period There is no pollutant emission during the operation of Luxi River in this project. Therefore, this evaluation focuses on the environmental impact of the project operation period from the perspectives of ecology, landscape and society. This project can improve the urban infrastructure construction, improve the ecological environment striker region, promote the construction and upgrading of urban functions forward area of the town environment, people, goods more smoothly, construction of urban ecological environment favorable to the main. The operation of the Luxi River remediation project can reduce the possibility of river channel blockage. The dike building remediation project restores the channel drainage and diversion irrigation capacity, which has a beneficial impact on the protection of cross-strait agricultural production. 8.2.1 Analysis of atmospheric environmental impact (1) Automobile exhaust A total of 30 parking spaces are set up in the project parking lot. The parking of the vehicles mainly depends on the surrounding area of the park. The number of vehicles inside the park is small, the time for vehicles to exhaust the exhaust gas is short, and the state has strict regulations on vehicle exhaust emissions, and the large area adopted in the project design. Greening will result in a certain purification of the ambient air in the project area. In addition, the parking is mostly self-provided vehicles, and the models are too small. Therefore, the automobile exhaust will not form a large concentrated pollution source, and has little impact on the environment. (2) odor The project plans to build a centralized garbage collection point and a number of garbage sorting bins. During operation, a small amount of odor will be generated, which will have a certain impact on the surrounding environment; the project public toilet will also produce a small amount of odor during the operation. Domestic garbage is odorous during the collection and transportation process due to cleaning, disinfection, and transportation that are not timely or in place. When the garbage is loaded and unloaded, the odor is accelerated, and the local air odor concentration is increased. However, at other

110

times, the garbage is in a closed state, and if properly managed, it will not affect the surrounding environment. The garbage collection point is located beside the main road of the park, which is close to the exit of the project, which is conducive to reducing the outbound route of garbage inside the project, and the EIA proposes that the waste entrusted by the sanitation department in the project should be cleared and transported in time. Shorten the stacking time of garbage in the park, so that the odor generated by the garbage room can be effectively controlled. At the same time, transport vehicles should be covered and closed during transport to reduce the impact of odor. The waste odor generated in the project after taking the above measures will not have a significant impact on the ambient air. Toilets during operation, as long as an ambient hygiene remains, cleaned; closed underground sewage treatment apparatus, generation of odor must be higher than 2 m above the roof or floor discharge, and maintain population activities Horizontal distance of 5m or more. Little impact on the environment. 8.2.2 Surface Water Environmental Impact Analysis According to the engineering analysis, the project wastewater is mainly domestic sewage, and the domestic sewage produced is treated by the grid well in the park to reach the third-level standard of Integrated Wastewater Discharge Standard, and then connected to the municipal sewage drainage pipeline for transportation to the Qianfeng DistrictWastewater Treatment Plant. Unified treatment of the "Urban Sewage Treatment Plant Pollutant Discharge Standards" (GB18918- 2002) Level A standard is discharged into the Qujiang River. From the above analysis, the wastewater operated by the project has been properly disposed of, and has little impact on the surrounding surface water environment. 8.2.3 groundwater Environmental Impact Analysis The service period of this project does not involve groundwater exploitation, and the sewage generated by it will be discharged into the municipal sewage pipe network through the pipe network and will not enter the groundwater. The greening area in the park is large, and the application of pesticides and chemical fertilizers in the greening area during the process of curing and pouring will have a certain impact on the groundwater. According to the data survey, the fertilizers and pesticides used in the green areas will enter the soil through leaching of atmospheric rainfall and garden watering. If they are used for a long time, they will enter the groundwater. The main pollution control index is the total hardness (calcium carbonate). Solubility total solid ammonia nitrogen (NH 3 -N), nitrite (based on nitrogen), nitrate (based on nitrogen). The project uses the physical and biological methods proposed by the EIA to remove insects, avoid the use of chemical agents, use water-saving irrigation technology during watering, save water resources, and not form surface and underground runoff, then the impact of the construction of the project on groundwater. It is acceptable. 8.2.4 Noise Environmental Impact Analysis The project is planned to be built into a city park with functions such as visits and excursions. It is equipped with some public facilities. There is no big noise source in the project. The noise generated

111

is mainly the noise of vehicles entering and leaving the vehicle, the noise generated by equipment operation, and tourists. Social noise, noise generated by park audio equipment, etc. (1) Vehicle noise If the vehicle is controlling the speed when driving 20km or less, which is a strong noise source is 65 ~ 75 dB (A), the attenuation with distance formula the point source, theradiation noise level at a distance of 20m were 39dB, 49dB, to meet the "Environmental Quality Standard" (GB3096- 2008) Class 2 standard requirements. (2) Equipment noise and vibration 1 pump and other equipment The project water supply pressure pump and fire pump equipment will produce intermittent noise and noise level. 80 to 90 dB(A), located in the enclosed management room of the park, and away from the project rest area. Since most high-noise pumps have a small workload and have little impact on the external environment, the field can be up to standard after adopting general sound insulation and vibration reduction measures. (3) Social noise and background music noise generated by tourists Social noise value generated in the crowded area 60~70 dB(A), the noise of the park background music system is mainly generated by the audio equipment, and the noise value is about 80~90dB (A). These two types of noise are discontinuous, the sound source sound level is very low, and mainly It occurs during the day and disappears at night, so this kind of noise has little effect on the environment. 8.2.5 Solid Waste Impact Analysis (1) Domestic garbage The solid waste of this project is mainly domestic garbage generated by tourists and management personnel. The domestic garbage is sorted and packaged to the garbage collection station, and then transported by the local sanitation department to the urban living city landfill for disposal, which has no obvious impact on the environment. (2) Garden waste The proposed project to maintain green space and trees will produce a certain amount of garden garbage, mainly litter, pruning branches and leaves, garden garbage is collected and transported by municipal vehicles to urban landfills. 8. 2.6 Environmental Positive Benefit Analysis (1) Flood prevention benefits The flood control benefit is to reduce the disaster opportunities and reductions of flood damage caused by construction projects, including the loss of casualties and the loss of national, collective and individual housing, materials, property and industrial and mining enterprises, commerce, transportation, electricity, communications, etc. The damage caused. The economic loss of the relief in flood control benefits is relatively straightforward and can be quantified, but the loss of casualties is reduced and it is difficult to express it in monetary terms. The flood control benefit only quantitatively calculates the economic losses caused by flood relief, and expresses the average annual

112

flood control benefit. Flood peak height is greater focus on remediation of this river, river bank erosion is more severe for two shore so far no any protective measures. The project mainly adjusts the river bank line, guides the flood to the river, and at the same time, through the new flood control and slope protection measures, the flood control capacity of the river section is raised from the current flood control standard of 3 to 5 years to the flood standard of 50 years.. (2) Environmental improvement and ecological benefits In combination with the development planning of the Qianfeng District, the construction tasks of the project will mainly meet the planning and construction of the new city and the group area, improve the flood control capacity of the planning area, and improve the river ecological environment, bank slope remediation and soil and water conservation,comprehensive land development and utilization, and beautification. Comprehensive tasks such as the environment and attracting foreign investment. After the completion of the project, as the river has been comprehensively rectified, it is no longer ravaged by floods, and the safety of people's lives and property is also guaranteed. The town will form a landscaping landscape integrating greening, beautification and ecological protection to make the people's living environment Real improvement has been made, and the Qianfeng District has been built into an ecological mountainous city with good ecological environment and pleasant environment. This part of the benefit is more difficult to quantify, only for qualitative analysis. Xiejiawan Park is located in the urban area of Qianfeng District. Because of its proximity to the municipal roads, there are many people around the city, the heat island effect is remarkable, the air quality is poor, and the ecological environment needs to be improved. Increasing plant diversity in the process of park construction can speed up the process of garden formation, improve the urban environment in time, reduce the feeling of depression caused by urban crowding and tall and monotonous buildings, and improve the anti-jamming of gardens. Capacity and stability, increasing the environmental effects of urban ecosystems and the ornamental value of gardens. With the rapid development of the urbanization process in the Qianfeng District, more urban urban residents yearn for nature to relax and breathe fresh air. In this context, the relative value of ecological landscape resources has increased, and there is a huge use value. The construction of the Xiejiawan Park project will form a healthy, stable and complete ecosystem. It will provide people with a comfortable and quiet environment, harmonious living with nature, leisure and holiday, and self-cultivation.

The processing method is characterized by simple structure, low cost, convenient management, and only needs to be cleaned regularly. The pH value of the flushing wastewater is high, but because of the large amount of water in the project, the impact is more obvious, and the neutralizing agent should be added during the operation. According to the characteristics of the gap drainage of the concrete mixing system, each system adopts a rectangular processing tank of uniform form and scale. The flushing wastewater is discharged into the pool every day, and the sediment is allowed to stand until the next shift, and the sedimentation time is more than 6 hours (add some chemicals). The size of the pool is 10 m (length) × 10 m (width) × 2 m (height). The water outlet of the pool is designed to be movable for easy removal and adjustment of the water level. The wastewater treatment process of the concrete mixing system is shown in Figure 9- 1.

116

Figure 9-1 Flow chart of production wastewater treatment Since the concrete processing wastewater treatment structure is simple and there is no problem of maintenance of mechanical equipment, the timing is mainly paid attention to during the operation. Management and maintenance work is integrated into the concrete mixing system without any separate institutions or personnel. 9.1.2 Oily wastewater treatment measures In view of the small amount of water used in the machine repair system and the low discharge of oily sewage, the treatment method of oil separation and sedimentation is adopted. Its characteristics are simple structure, low cost, and convenient management. It only needs to be cleaned regularly.

Figure 9-2 Flow chart of oily wastewater treatment A rectangular treatment tank shall be set up in the mechanical repair station of the construction area. The oily sewage shall be used for sprinkling water and dust in the construction area after being treated by oil separation and sedimentation, and shall not be discharged. The cleaned oil shall be entrusted to be qualified by the unit, and shall not be disposed of by the qualified environment. Secondary pollution. 9.1.3 Foundation pit wastewater treatment measures The geotechnical particles and cement mortar in the foundation pit wastewater are easier to precipitate. According to the experience of similar engineering, a certain area is set up in the foundation pit as the collecting basin. The foundation pit wastewater is allowed to stand in the collecting tank for 1-2 hours, and the sedimentation treatment is followed. Use, do not efflux. 9.1.4 Domestic sewage treatment measures The engineering office and living lease the surrounding private houses, the living facilities of the construction personnel depend on the original facilities of the local private houses. Therefore, the domestic sewage generated by the construction workers can be collected and disposed of according to the existing facilities, used as agricultural fertilizer, not discharged, and the surrounding environment. The impact is within acceptable limits. 9.2 exhaust gas According to the construction characteristics of the river improvement project, the secondary dust of the construction site is the main source of air pollution. In order to minimize the emission of exhaust gas during construction period and avoid the spread of harmful gases and dust in the project area and surrounding environment, the environmental impact assessment requires that the construction party should strictly follow the Notice of the State Environmental Protection Administration and the Ministry of Construction on Effectively Controlling Urban Dust Pollution. and related construction specifications of the Ministry of construction, refer to "dust pollution prevention technical specifications" (HJ / T393-2007) and other documentation requirements, strengthen management, effective control of construction dust pollution. From the perspective of environmental protection, after the corresponding environmental protection measures are taken, the exhaust gas generated during the construction period of the project has little impact on the surrounding area. 9.3 noise

117

The noise pollution during the construction period is the main pollution problem of this project, which is easy to cause noise disturbance. Therefore, the principles specified in the section on noise analysis of engineering analysis should be strictly followed, and prevention and control should be carried out in particular, especially paying attention to the supervision and management of night construction. 9.4 Solid waste The solid waste generated during the construction period is mainly construction materials such as earth and stone works, concrete pouring, construction waste and domestic garbage generated in stone masonry. The excavation of the project produces a large number of earth and stone, and all the excavated earth and stone are used to backfill the embankment. In the foundation construction of the project, the loose foundation is prone to water and soil loss under the scouring of precipitation or surface runoff, and the construction of retaining walls and drainage ditch in the temporary dumping site to avoid rainwater and surface water scouring, and timely backfilling the piled soil, reducing Stacking time; construction wastes such as iron wire, steel bars, packaging boxes, etc., which are collected and transported, are collected and transported to nearby waste collection stations, rigorously arranged and littered; construction wastes should be promptly transported to the construction waste dumps approved by the county government. Dumping; for the construction workers' domestic garbage is prohibited from burning in the construction area, and garbage collection boxes or centralized collection points are set up in the living area, and then collected and sent to the sanitation department for unified disposal to prevent the surface water from being washed away by rain. 9. 5 ecological restoration measures (1) The main roads occupied by construction are mainly cultivated land. Therefore, after the completion of the construction, the land will be rectified for re-cultivation. During the construction period, temporary drainage ditch shall be arranged on the outside of the road, and the temporary drainage ditch arranged by the sedimentation tank and the embankment line shall be connected downstream of the drainage ditch. Construction vehicles should travel along the construction road as much as possible to avoid rolling the land outside the construction road. (2) The construction camp area is temporarily occupied, and the land use type is mainly cultivated land. Therefore, the topsoil is stripped before construction, and the land is rectified after the construction is completed, so that it can be re-cultivated. (3) Temporary drainage ditch is arranged around the temporary slag yard for drainage. The downstream of the drainage ditch is connected to the outer drainage ditch of the embankment line. The surrounding area is blocked by temporary soil bag retaining wall, and the surface is covered with temporary tarpaulin. Because the temporary slag yard is a temporary land occupation, the land use type is mainly wasteland, and after the waste slag is cleaned, the grass seeds are planted so that the vegetation can be restored. (4) Reasonably arrange the construction period, avoid the construction of the rainy season, and minimize the soil erosion; (5) During the construction period, strengthen construction management and supervision, standardize construction behavior, minimize vegetation loss caused by construction land occupation and construction activities, and reduce damage to wildlife habitat; (6) Standardize construction behavior, rational and orderly construction, optimize construction organization, and carry out construction in the same construction section in the same direction. The adjacent construction sections are staggered during construction peak period to avoid large-scale construction of the same area and reduce disorderly construction. Disturbance of the terrestrial

118

ecological environment. During the construction period, in the form of announcements, leaflets, newspapers and meetings, the publicity and education of construction workers and the promotion of common sense of wildlife will be strengthened to raise awareness of environmental protection; construction workers are prohibited from hunting frogs and snakes. Wild animals such as mammals and birds and other activities that hinder ecological protection.

Environmental Management and Monitoring Plan Table (10) Objective 1 0.1 environmental management plan One of the key objectives of environmental impact assessment is to clarify the possible environmental impacts of related activities during project implementation and operation, so as to develop a set of technically appropriate, financially acceptable environmental impacts that meet the environmental protection requirements of the relevant regions. Measures. These measures are usually identified during the environmental assessment phase, and then a monitoring plan appropriate for the construction period and operation period management is proposed in the environmental management plan. The role of this environmental management plan is to list the environmental impact mitigation measures, monitoring measures and institutional settings that will be implemented during the implementation and operation of the project to prevent negative impacts on the environment. The plan will point to the key links between feasibility studies (or design options) and the environmental impact mitigation measures proposed in this evaluation and how to implement them. For each proposed measure, this environmental management plan will clarify its technical content, budget costs, implementation plan, roles and responsibilities of each relevant department, source of funds, and monitoring methods. 1 0. 2 Environmental Management Organization (1) Compliance monitoring and impact monitoring The environmental management plan includes two types of monitoring activities that are relatively independent: compliance monitoring and impact monitoring. “Compliance monitoring” (ie, whether it is implemented) refers to the special regulations in the control of the implementation of the project to comply with all laws and regulations applicable to the project, namely national laws and regulations, local laws and regulations and environmental protection of the construction unit. The assumption implied by this monitoring is that if all of the above regulations are enforced, the impact should be within the scope of the license. “Impact monitoring” refers to the environmental monitoring plan proposed in the implementation of the environmental impact report form, or the follow-up investigation, monitoring and monitoring work according to the specific impact factors added during the construction and operation phases of the project. The requirements and measures for mitigating impacts identified in this evaluation mainly involve the following aspects: 1 Strengthen the preparation and formulation of the contract so that the construction unit can be required to perform relevant environmental responsibilities. 2 Set up an efficient and powerful organization to monitor the environmental impact of construction activities and implement appropriate mitigation measures. 3 Reduce the loss of precious cultural and ecological resources. The above requirements and measures and supporting monitoring plans are detailed below. (2) Strengthening contract work for environmental management 1 contractual obligations Defining the task and the corresponding distribution of rewards will give the construction unit the best response, which is the basis of the construction contract that relies on detailed technical

120

specifications and corresponding bills of quantities. In order to achieve good results, the contract documents shall be contractually stipulated in the environmental obligations of the construction unit, but they shall be paid separately. The two should be combined because the terms of payment affect the development and presentation of the specification. Therefore, preparing detailed environmental technical regulations for the construction unit is the first measure to mitigate environmental impacts before the bidding process. The purpose of this is to finalize the contract documents that will clearly determine the responsibilities of the construction unit, the corresponding workload and related The number of fees. 2 Preparation of environmental technical regulations The environmental technical regulations formulated for the construction unit include the following four items: environmental protection management, worker resident and occupational health management, safety management, and social management. Each item should describe the responsibilities of the construction unit and a performance indicator that describes the assessment at the time of payment (for impact monitoring). 1) Description of the duties of the construction unit Environmental protection management stipulates the responsibility of the construction unit in preparing the site environmental protection plan. The plan is to ensure that the site and the surrounding environment are protected from any possible adverse effects. Construction site environmental protection plan should include workers resident units and construction of waste management facilities and procedures, soil and water conservation measures after the completion of construction and environmental restoration measures designed to safeguard the cultural, environmental monitoring and prevention measures for water pollution (water, air, etc.). For each of the above measures, the environmental technical regulations will clearly specify to the construction unit the required standards or quality objectives. Basic standards for worker residency and related facilities that should be implemented by workers’ residency and occupational health management regulations, including accommodation conditions, food supply and canteens, and waste management, water supply, site sewage treatment and sanitary conditions. Safety Management Regarding safety-related matters, the environmental regulations will solve two problems: 1. On-site safety, personal protective equipment (labor supplies) and medical care; 2. Off-site safety issues. On-site safety, personal protective equipment (labor supplies) and medical aspects mainly require measures to be taken by the construction unit to ensure that it is comparable to international practice standards and establish appropriate medical emergency procedures for its workers. Off-site safety aspects will cover all relevant safety issues outside the site, including the impact and hazards of transportation caused by transporting equipment to and from the site. In terms of public safety content in off-site safety, measures to be taken before and during construction by the construction unit will also be required to reduce the risk of public injury and serious impact on local residents. Social management formulates the framework clauses for the construction unit to conduct social management related to construction activities. Most of the conditions will focus on how to reduce the pollution and inconvenience caused to residents. It is estimated that public nuisance or inconvenience mainly comes from noise, temporary closure of roads, temporary power outages when laying sewage pipes, water, gas or telephone lines. The construction unit will prepare a

121

pollution control plan, which will be discussed with the owner's environmental management division. Discussions will also be held at a briefing or consultation meeting with residents (or their representatives) who may be affected by the construction. The issues discussed will focus on the steps that the construction unit should take before closing the road, water, electricity, gas or other services, as well as general inconveniences (public hazards) such as access to houses or shops, noise and air pollution. 2) Description of the completion assessment indicators In the prepared environmental technical regulations, the performance evaluation indicators that will be monitored during the on-site supervision process shall also be specified. For projects that can be quantitatively assessed: the majority of the responsibilities of the construction unit are measurable, and for such responsibilities, quantitative indicators should be monitored. Payment to the construction unit shall be based on the values of the measured indicators on site. For projects that cannot be quantified: certain environmental responsibilities are difficult to quantify. A typical example is the protection of the adjacent area of the construction site. It is unrealistic to specify how many trees are cut by mistakes, or how much cubic meters of material is dumped on the roadside. Nevertheless, for such unmeasurable items, measures to reduce such negative impacts should be specified, and it should be clearly stated which circumstances can cause the construction unit to be unable to receive payment. 3 Environmental responsibility payment procedures Appropriate payment procedures are the most effective means of ensuring that construction units perform their environmental duties. The payment process should give the executive department maximum assurance that it will only be paid when the work is completed satisfactorily and satisfactorily. In addition, the payment process should be motivating and can motivate the construction unit to perform its environmental duties with the best results. When preparing environmental technical regulations for the construction unit, these issues will be discussed with the owner's environmental management division, the project owner's executive agency and the lending bank. The parties will also consider payment options related to the most appropriate and acceptable environmental responsibilities. (3) Environmental management agency 1 project organization In order to ensure that all current national, provincial and municipal environmental laws, regulations and standards can be implemented during the preparation and implementation of the project, the project owner's executing agency will set up an environmental management division. The Environmental Management Division will be responsible for directly coordinating and organizing monitoring activities during the construction process and contacting relevant government agencies to ensure effective implementation of the environmental impact mitigation measures determined in this environmental management plan. The Environmental Management Division consists of two environmental management professionals (preferably a senior and a junior). Two professionals will be assisted by the permanent staff of the project owner's executive agency (such as secretary, accountant, etc.). To facilitate the execution of its tasks. The person in charge of the environmental management division must have a strong professional background related to the construction environment of the project, and have the management

122

ability to organize the daily work of the division, manage the budget, establish and maintain contact with relevant parts of the government and The ability of the project executing agency and the project management office to report. Compliance monitoring: In terms of on-site monitoring, the environmental management division will rely on construction supervision engineers and environmental supervision teams. The Environmental Supervision Team consists of a construction environmental supervision consultant and two on-site environmental supervisors. Impact Monitoring: The Environmental Management Division will delegate all impact monitoring to one or several independent environmental monitoring agencies. Priority is given to local environmental monitoring agencies with local monitoring qualifications that are familiar with local conditions and have accumulated a wealth of monitoring data. 2 roles and responsibilities 1) Technical support environmental experts Technical support environmental experts will provide technical support to the Environmental Monitoring Group, the Environmental Management Division, the Project Owners Execution Organization and the Project Management Office. 2) Construction supervision environmental consultant The Construction Supervision Environmental Consultant is a local expert who will be responsible for overseeing environmental issues related to construction activities and coordinating the work of on-site environmental supervisors. 3) Site environmental supervisor The main duties of the on-site environmental supervisor are to supervise the construction activities of the construction unit and other project-related activities such as land acquisition and demolition. At the same time, it is also responsible for ensuring that such activities are fully implemented in accordance with the project's environmental requirements, regulations, objectives and objectives. They will also ensure the coordination of work in the field and representatives site is responsible for land acquisition and relocation of government departments and responsible for monitoring the activities. To accomplish this task, the site environmental supervisor will be responsible for understanding the project's technical specifications, environmental regulations, and the responsibilities of the construction unit, especially how these documents are applied to the monitoring tasks. The construction supervision environmental consultant will ensure that the site environmental supervisors have a good understanding of the project documents. Before the construction of the project begins, the construction supervision engineer will train the environmental supervisor. 4) Independent environmental monitoring agency The Environmental Management Division will contact an independent environmental monitoring agency to conduct environmental impact monitoring (water quality, noise and air quality, etc.) in the project area. 10.3 Environmental Monitoring Plan In order to ensure that the mitigation measures and environmental responsibilities are implemented strictly and effectively during the construction phase, it is necessary to develop a plan for monitoring activities, which includes two types of monitoring: Compliance monitoring: the overall environmental monitoring of the construction site and construction activities.

123

Impact monitoring: Specific monitoring of water quality, air quality and noise. 10.3.1 monitoring of construction activities Compliance monitoring will be carried out throughout the construction / construction period of the project, with the construction supervision environmental consultant responsible and the on-site environmental supervisor. The on-site environmental supervisor will monitor the on-site activities on a daily basis, and the construction supervision environmental consultant will conduct routine inspections at each site every month. If there is any inconsistency, a special inspection will be conducted. According to the environmental regulations of the construction unit, the Environmental Supervision Team will monitor all aspects of activities specified in the environmental technology regulations. Including environmental protection management, worker resident and occupational health management, safety management and social management 10.3.2 Environmental Monitoring Plan Environmental monitoring includes two phases: construction period and operation period. The purpose is to comprehensively and timely grasp the project pollution dynamics, understand the environmental quality change degree, impact scope and environmental quality dynamics of the project construction in the region, and timely report to the competent department. Feedback information provides a scientific basis for the environmental management of the project. According to the environmental impact prediction results, sensitive points with more obvious pollution are used as monitoring points. From the pollution situation during construction and operation period, the monitoring content selects the surface water environment, atmospheric environment and acoustic environment that are affected greatly. The monitoring factors are determined according to the pollution characteristic factors in the engineering analysis. The monitoring and analysis methods are monitored and analyzed by the corresponding projects in the country. Methodology, evaluation criteria for the implementation of national standards for environmental impact assessment.

The above plan particularly emphasizes the improvement of urban and rural infrastructure systems and the creation of a livable environment. Responsive to the relevant planning and requirements of the State, Sichuan Province, Guang'an City, and Qianfeng District, in line with relevantplanning policies. 11.1. 4 Environmental quality status evaluation conclusion (1) atmosphere: monitoring results show that the air SO 2, NO 2, PM 10 is not exceeded phenomenon, ambient air quality to meet "Ambient Air Quality Standard" (GB3095- 2012) of the secondary standard. (2) Surface water: The monitoring results show that the BOD 5 and COD in the monitoring section of the Xiejiawan Reservoir exceeded the standard, the monitoring section and CODin

131

the lower reaches of the Luxi River exceeded the standard, and the other indicators met the Environmental Quality Standard for Surface Water (GB3838). Class III waters standard in- 2002). The main reason for the over-standard of the Xiejiawan Reservoir is that a residential area of a certain scale has been built around it, but the corresponding supporting rainwater pipe network has not been completed and put into use in time. Some domestic sewage is connected to the reservoir along the rainwater ditch, with the municipal pipe. The water quality will be improved and the water quality will be improved. The main reason for the over-standard section of the lower reaches of the Luxi River is that there are residents in the lower reaches of the rectification section. The domestic sewage is not included in the municipal pipe network and goes straight into the Luxi River due to the area. Residents have been included in the relocation plan. After the residents are relocated, the domestic sewage will be discharged into the Luxi River and the water quality will be improved. (3) Acoustic Environment: monitoring results show that between daytime and night meet the noise "Environmental Quality Standard" (GB3096-2008) class 2 standard. (4) Sediment Environment: According to the status Luxi River sediment test results with the standard value of comparative analysis, the factor indicators have reached "SoilEnvironmental Quality - soil contamination risk control standards of agricultural land (Trial)" (GB15618- 2018) risk The screening value requires that the sediment of the Luxi River of this project has not been polluted. (5) Ecological environment: Most of the proposed projects and the surrounding areas are urban environments, with people as the main life groups, endangered animals and plants, no natural environmental protection zones and cultural relics. 11.1. 5 Environmental Impact Control Measures 11.1. 5.1 Pollution analysis during construction period Exhaust gas: The construction of the fuel machinery is intermittent, and the number of uses is small. After strengthening the maintenance and repair of the equipment, the impact on the ambient air is small; the construction dust will have a certain impact on the surrounding environment, and the construction operation will be closed. After the measures such as sprinkling water and dust suppression, the impact on the environment is small. Waste water: After the domestic sewage of construction workers is collected, it will be transported to the municipal sewage treatment plant for disposal in a timely manner; the construction wastewater will be reused after sedimentation treatment; the drainage of the silt dump will be discharged through the setting of multi-stage sedimentation tanks in the reservoir area. After reaching the first-class standard of Integrated Wastewater Discharge Standard (GB8978-1996), the water is discharged into the Luxi River. After the above measures are taken, the wastewater during construction period has little effect on surface water. Noise: The construction machinery is noisy and has different degrees of influence on the surrounding environment. Take reasonable arrangements and limit the operation time, limit the entry of high-noise equipment, strengthen equipment maintenance, rationally arrange the position of construction machinery, and take effective measures to control the environment after sound insulation, vibration reduction and noise reduction measures. The noise generated by the transport vehicle is also large, but it belongs to the mobile source and has a short duration and has little impact on the environment. Solid waste: The construction workers ' garbage sites are collected and disposed of by the

132

municipal sanitation department; the construction wastes and abandoned materials generated during the construction period are transported to the designated site for landfill treatment; after the dredged sediment is dried, the landscape area is backfilled as the landscape project. Earth. After the above measures are taken, the impact of solid waste during the construction period of the project is small. Ecological impact and soil erosion: The land occupation of the project will cause a fundamental change in the land structure, the physical and chemical properties of the soil will change, the urban ecosystem will be more obvious, and the surrounding natural landscape will be blocked. Taking full advantage of the original terrain, minimizing excavation, restoring vegetation as soon as possible, and restoring vegetation to plants with strong ecological suitability, the impact on the environment is limited. 11.1. 5. 2 Environmental impact during operation period There is no pollutant emission during the operation of Luxi River in this project. Therefore, this evaluation focuses on the environmental impact of the project operation period from the perspectives of ecology, landscape and society. This project can improve the urban infrastructure construction, improve the ecological environment striker region, promote the construction and upgrading of urban functions forward area of the town environment, people, goods more smoothly, construction of urban ecological environment favorable to the main. The operation of the Luxi River remediation project can reduce the possibility of river channel blockage. The dike building remediation project restores the channel drainage and diversion irrigation capacity, which has a beneficial impact on the protection of cross-strait agricultural production. (1) Environmental impact of waste gas: During the service period, the atmospheric pollutants are mainly exhaust gases emitted by vehicles. In order to reduce the exhaust emissions from vehicles, road traffic management in the park should be strengthened, and the vehicles in the area should be kept in order and smooth to prevent automobile exhaust pollution due to traffic jams and vehicle idling.. At the same time, the two sides of the road and the middle separation belt should be combined with three- dimensional greening of grass, shrub and arbor. The dust-proof measures combining greening and hardening should be adopted. When the road shoulder and the middle partition of the road are greened, the inner soil surface should be lower than the road side wall. Building, reducing wind erosion and water erosion. The park service facilities have no exhaust emissions, mainly the odor of the biochemical treatment tank of domestic sewage. There is a special ventilation duct to access the super-roof of nearby buildings and structures, and away from pedestrian passages and crowd gathering sites. At the same time, the public toilets in the park are equipped with a pumping and exhausting system. The air is updated by the sending and exhausting systems, cleaned daily, and regularly disinfected. The odor of the public toilets has little impact on the environment. The project is planned to set up garbage bins with “ recyclable ” and “ non-recyclable ” delivery ports in public areas such as main roads, secondary roads, sidewalks, management and service facilities, and public areas inside buildings. The main collection of garbage points in the plate is set. Domestic garbage is mainly substances that are easily fermented and deteriorated, such as food. During the storage process, odor is emitted due to fermentation, and it is easy to produce mosquitoes and flies. After the project is completed, the flow of people is dense. It is proposed to set up a garbage collection on each of the two plots. Point, the garbage collection point must

133

avoid the concentration of people, the garbage collection point must be cleaned up in time and kept clean. Secondly, the sealing of the garbage storage facilities is guaranteed, and the garbage is removed from the sanitation part every day to reduce the garbage retention time. Finally, regularly spray medicine or lime to prevent flies and deodorants. Little impact on the environment. (2) Waste water According to the engineering analysis, the project wastewater is mainly domestic sewage. After being treated by the grid well to reach the third-level standard of Integrated Wastewater Discharge Standard, it is connected to the municipal sewage drainage pipeline and sent to the Qianfeng District Wastewater Treatment Plant for unified treatment to achieve the urban sewage treatment. The discharge standard of the pollutants of the factory (GB18918-2002) is discharged into the Qujiang River after the first-class A standard. (3) Environmental noise There is no big noise source after the project is planned to be built. The noise generated is mainly the traffic noise of vehicles entering and exiting, the noise generated by equipment operation, the social noise generated by tourists, and the noise generated by park audio equipment. For vehicle noise: park roadway vehicles control speed at speed Below 20km/h, and set warning signs such as warning and speed limit. Tall tree saplings are placed on both sides of the roadway to achieve sound absorption and noise reduction. For equipment noise and vibration: The proposed project uses low-noise equipment, and the equipment is placed in the equipment room, and away from the rest of the project, the pump will do basic shock absorption, which will reduce noise pollution. The water pump inlet and outlet pipes are provided with flexible rubber joints, and elastic pipes and hangers are arranged on the water pipes to effectively absorb noise. For social noise and background music noise generated by tourists: set warning signs in the park, and loud noise is strictly forbidden. The installation of the park audio equipment is away from sensitive points such as surrounding schools, and it avoids playing at noon 12 : 00~14 : 00 and at night. The music played is mainly light music. When using the sound-affecting equipment for a long time, it should be publicized to the surrounding people. To avoid affecting the surrounding residents and tourists. Through the above measures, the impact of the service period of the proposed project on the surrounding residents and tourists can be reduced. (4) Solid waste There are no toxic and harmful solid wastes in melon peels, meat residues, paper, packaging materials, etc. of main organic substances in domestic garbage. The project type is mainly for public places. The garbage bins should be set up along the square roads, and there are special personnel responsible for environmental sanitation and cleaning work. The garbage is bagged and collected by a special person every day, and then sent to the garbage dump for disposal by the sanitation department. The resulting garden garbage is cleaned and collected by the park cleaners, and is transported by the sanitation department to the garbage dump. Sludge generated within the project grill well by a professional disposal unit Qingtao regularly. 1 1.1.6 Comprehensive conclusion The construction goal of this project is to promote the construction of ecological towns in the Qianfeng District, create a harmonious ecological living environment and enhance the

134

livability of the city. The project construction conforms to the national industrial policy and conforms to the environmental function zoning of Guang'an City and Qianfeng District. The project has adopted effective pollution prevention and control measures, pollutants can be discharged to the standard, and the surrounding environment can maintain the status quo.
