Luohandong~Dingxi Expressway Environmental Monitor Report Gansu Roads Development Project Luohandong~Dingxi Expressway Environmental Monitoring Report (the 1st and 2nd Quarter of 2008) I. Foreword This Expressway is the artery of transportation for Longdong Region (eastern part of Gansu Province). As being an entrance and exist to the east, it plays an important role in connecting the east with the west in the State road network. It also a key sectional part constitutes Gansu Trunk Highway Network so-called “Four Longitudinal, Four Transversal and Four Importance”, and a bridge promoting exchanges among Gansu, Qinghai, Xinjiang and Ningxia Provinces in the economic fields, and also an important passageway to Tibet region. This Project is partially financed by Asian Development Bank. The construction period is from 2006 to 2009. To ensure the implementation of environmental protection work for this Project, and based on the monitor plan indicated in the “Environmental Impact Assessment Report of Luohanddong~Dingxi Expressway” (EIA), in 2007, Gansu Provincial Communications Department Changda Highway Co., Ltd (GCHC) entrusted Environmental Evaluation Center of Pingliang City, Gansu Province (the Center) to conduct monitor of the current environmental quality during construction period in the project area. To fulfill this task, some relevant technicians have been appointed to make site survey during March 2007. In accordance with relevant environmental quality criteria and monitor technical specification issued by SEPA, and required by the EIA and ADB, it is proposed a monitor scheme for the Project, i.e. to conduct environment monitor for 3 years during the construction period, and 4 times each year (once in every quarter, one report in every half year). Upon the agreement made by ADB and GCHC in regard with this scheme, a monitor contract has been signed. According to the contract, the monitor of the current environmental quality during construction period has been done in year 2007 and 1st half of 2008, Based on these monitors above, the report is drawn out. 3 Environmental Monitoring Center of Gansu Province Luohandong~Dingxi Expressway Environmental Monitor Report II.

Brief Introduction of the Project 3.1 Basic Information of the Project This Expressway starts at Luohandong of Jingchuan County and ends at Shibalipu of Dingxi City to the northeast, passing through Jingchuan County, Pingliang City, Jingning County, Huining County and Dingxi City, with total length of 231.056km. 3.2 Brief Introduction of Natural Environment 3.2.1 Eco-environment 4 Environmental Monitoring Center of Gansu Province Luohandong~Dingxi Expressway Environmental Monitor Report From east to west, the proposed expressway passes by valley area of Jinghe River at east of Liupan Mountain, forestry area of Kongtong Mountain and loess plateau area at west of Liupan Mountain. The Jinghe River, which categories agricultural type, is distributed mostly the irrigated land; Kongtong Mountain, which situated at low mountainous area of Liupan Mount, belongs to natural ecologic type and is suitable for growth of trees and multiplying of wild animals; the loess plateau, covered by loess largely, on which sparsely grows vegetations but some herbage vegetables, has potential in danger of soil erosion due to the relatively fragile ecology. 3.2.2 Water System From east to west, the route passes Jinghe River, Dongxia Reservoir, Hulu River, Gouwa River, Zuli River and Zu River. Liupan Mountain is the dividing ridge of water system in this district. The rivers in east part belong to Jinghe River and those in west part belong to Weihe River. Jinghe River is confluent with Weihe River, which belongs to the secondary tributary of Yellow River, and is an important tributary of Weihe River. 3.2.3 Soil Types, Animals and Vegetables Jingchuan County and Kongtong District are mostly covered with loessal soil. Soil erosion can be categorized into loess plateau ravine area, loess hilly ravine area and gully area, which is mainly due to water power and identified as light corroding degree. Huining County and Dingxi District are mostly covered with grey cinnamon soil, heilu soil and loessal soil. The route is traveling through a loess hilly ravine area, with large hypsography, some sections are passing through relatively flat terrace. Jingchuan County, where the weather belongs to continental climate, has no large scaled natural forest and grass. Trees there include poplar, acacia, paulownia, stink bug, elm and spine date etc. Kongtong District, where the weather belongs to wind continental climate, has 3970 thousand mu forestry land, in which the forestry coverage rate reaches 17.98%. Forestry holds an advantageous position in the province. There are over 1000 species of vegetations including some 100 types of economic plants and 5 Environmental Monitoring Center of Gansu Province Luohandong~Dingxi Expressway Environmental Monitor Report medicinal vegetations such as sea buckthorn and liquorice, and 243 species of wild animals. The aquatic productions are mainly fresh water fish and soft-shelled turtle. Nature protection area of Kongtong mountain, covered by forestry taking over 70% of the total area, belongs to provincial protection areas. There are more than 1000 species of vegetations, 32 kinds of forestation trees, approximate 30 kinds of vegetations for raising and grazing such as vegetations in pea and standing grain families. There are 243 kinds of vertebrate belonging to 25 orders, 65 families. According to the inventory of wild protection animals released in 1989, there are totally 13 species national protection animals, in which 3 species are class I and 10 species are class II protection animals. There are plenty of insects there. By primary investigation, there are 907 kinds of insects belonging to 16 orders, 107 families and 454 genuses. Jingning County, Huining County and Anding District, in which vegetation there include natural vegetation and man-made vegetation. Natural vegetations are mainly herbage with sparse and low fraction of coverage. Man-made vegetations are formed by tree and grass planting. There is only 330 acre natural shrub on Tiemu Mountain in Huining County. Animals mainly include: wolf, fox, sheep and hare etc. 3.2.4 Weather The west of Liupan Mountain is located at sub dry area of mid temperate zone, and that at east of Liupan Mountain belongs to sub humid area of south temperate zone. In whole region, the climate is dry and hot in summer, and cold in winter with small precipitation and big evaporation capacity. Natural vegetation there is sparse, and farm crop mainly belongs to dry corp. In the Project area, the average annual temperature is relatively lo. The period with deposited snow and ice in winter is usually last several months long. Big evaporation capacity, fog appears in rainy season with low visibility there. The main weather features listed as in the following table 3-1.
