Introduction This report is an executive summary report of environmental assessment for Shaanxi rural drinking water supply and sanitation project loaning from World Bank and funding by the donation of DFID. It is one of project documents for an appraisal by World Bank. To improve drinking water supply and sanitation conditions in some remote rural areas in Shaanxi province, Shaanxi provincial government decided to initiate a program on rural drinking water supply and sanitation in 90 project blocks within 15 counties (city) by seeking a loan from World Bank and funding of DFID. It is expected to provide drink water supply and a better sanitation conditions for about 321,000 populations in 335 villages. The investment is estimated as 37.5 million USD, among which 12.5 million USD from loan of World Bank and 12.5 million from the donation of DFID and 12.5 million from domestic sources. This project was classified as category B by World Bank in September 2005. An environmental assessment report and environmental management plan were required. A scope report for this environmental assessment was provided. In November 2005, World Bank required to undertake and complete an environmental assessment for the 1st group of project areas (20% (4 project counties/districts)) and then develop a policy framework for environmental assessments of the remaining 80% project areas. Shaanxi provincial development and reform commission assigned Shaanxi Institute for Environmental Sciences Research and Design (short for Shaanxi Environmental Institute (SEI)) to undertake an environmental assessment for Shaanxi rural safe drinking water and sanitation project in November 2005. An environmental assessment for the 1st group of project areas (20%) and a policy framework for environmental assessment of remaining 80% project areas were completed by SEI in September 2006. This executive summary report was prepared based on the full report of environmental assessment of the 1st group of project areas and the policy framework for environmental assessments of remaining 80% project areas. This report is prepared according to Chinese relevant laws and regulations for environmental assessment, World Bank environmental policies, outline and appraisal remarks of environmental assessment provided by World Bank preparation and pre- appraisal, appraisal missions. The full environmental assessment report includes three parts: 1) executive summary report (part A, this document); 2) main report (part B, includes the policy framework for environmental assessment of remaining 80% project); 3) environmental management plan (part C). This executive summary report provides a summary on the main report and environmental management plan. 1 Environmental Impact Assessment Report Shaanxi Rural Drinking Water Supply and Sanitation Project by Using World Bank Loan and DFID Donation 2. General Description of the Project This project mainly includes three elements i.e. water supply, improvements in toilets, and garbage disposal. Water supply includes utilizing existing water reservoirs, channeling water from nearby rivers, on-site deep wells, and existing tap water plants. According to the project planning, new water supply capacity of 21,879m3 /day will be increased via newly building-up, modification, and expansion of existing capacity, 73,978 toilets will be built or improved, and 796 garbage disposal sites at villages will be constructed.

    www.nature.com/scientificreports OPEN A mechanical insight into the triggering mechanism of frequently occurred landslides along the contact between loess and red clay Baoqin Lian1, Xingang Wang1*, Kai Liu1, Sheng Hu2 & Xiao Feng3 The triggering mechanism and movement evolution of loess-red clay landslides, which occurred frequently along the contact between the loess and red clay on the Loess Plateau, are closely related to the mechanical properties of the contact surface. This work presents an experimental investigation on loess, clay and loess-red clay interlaminar (LRCI) samples obtained from a typical loess-red clay landslide in northern part of Shaanxi province of China, using a series of ring shear tests, microscopic observation and scanning electron microscopy tests, in an attempt to explore the mechanical behavior of loess, clay and LRCI samples with variation in moisture content, normal stress and shear rate. The results revealed that for all specimens, both the peak shear strength τp and the residual shear strength τr decreased with increasing moisture content, among which, moisture content has the greatest infuence on the τp and τr of red clay, followed by the LRCI specimen, and the loess specimen is least afected by moisture content. Meanwhile, exponential functions describing the correlations between shear strength and moisture content of LRCI, red clay and loess specimens were proposed. Furthermore, the macroscopic morphological characteristics and the microstructure of shear surface obtained from the LRCI specimens showed that a localized water accumulation was built up within the shear surface as the water content increases to some extent, and a high degree of liquefaction developed within shear surface when the moisture content reached to the saturate degree.

    Advances in Social Science, Education and Humanities Research, volume 250 8th International Conference on Education, Management, Information and Management Society (EMIM 2018) Environmental Problems and Countermeasures for Sustainable Development in a Declining Mining City Tongchuan Zhao Aning*, Wang Jianhui, Chen Huaqing and Zhang Jianghua 1Xi’an Center of China Geological Survey, Xi’an, 710054, China [email protected] * The corresponding author Keywords: Declining mining city; Tongchuan; Environmental problems; Countermeasures Abstract. Tongchuan is a resource-based city with coal, cement and clay minerals production. The development of mining industry has made a great contribution to the social and economic development of the city. With the depletion of mineral resources, the city faces two kinds problems: First, for a long time of mineral resources exploitation, the natural landscape has been deeply damaged, and many problems such as forest vegetation destruction, environmental pollution and geological disasters have greatly increased; the second is economic growth of mineral resources industry began to decline. So this city needs the alteration of industrial structure, and a large number of labor transfer. In this paper, we explained the types of serious environmental problems caused by mining development based on Tongchuan mine geological environment survey. Accordingly, we discussed the countermeasures of mine geological environment governance and the sustainable development of the economy. Introduction Tongchuan is a medium-sized mining city with resource development as its pillar industry and its coal resources have been mined for thousands of years. Since 1955, the cumulative production of raw coal has reached 360 million tons. The historical subjects are invested by the state and the production profits are benefit to the state, which has made important contributions to the national construction and local economic development.

School of Earth Science and Resources, Chang’an University, Xi’an 710054, China Abstract: This paper analyzes the spatial variation in soil erosion in the loess hilly-gully region of northern Shaanxi Province, China. It sums up existing research, describes the factors that drive soil erosion, and uses geodetection to investigate the factors individually and in pairs. Our results show that soil erosion in the loess hilly-gully region of northern Shaanxi is mainly hydraulic erosion. There are significant spatial differences in the severity of soil erosion in the region. Generally, it is more severe in the north and west and less severe in the south and east. Individual factor detection results show that the major risk factors affecting soil erosion are human population distribution, precipitation, land-use type, elevation, and soil type. In- teractive detection results show that interacting factors play much bigger roles in soil erosion than do individual factors. Based on forced detection results from different periods of time, we can see that forest and grass coverage, urbanization, and economic development in the study area all clearly inhibit soil erosion.
