摘要：Taking once during as the study area, the course by using the DPSIR model and a lot of literatures screening of high frequency index, and quantitative analysis combined with the expert appraisal method, on once during regionalization index system establishment, course planning method was studied, determining the topographical features, water loss and soil erosion prevention and control system, land exploitation and utilization of direction, after years of average rainfall, population density, coverage of trees, soil and water loss area total area percentage as indicators of dividing the partition of soil and water conservation, such as in the villages and towns as the basic unit. Through principal component analysis, cluster analysis, the GIS space superposition method for regionalization, will once during divided into course will once during is divided into six course four areas: the southern mountain freeze-thaw district, Zhongshan in southern hilly water conservation ecological reserve, with low hills in southern soil conservation area, central oasis environment farmland protection area in northern desert ecological maintenance, low mountain in northern wind sand area, ecological maintenance area 6 level 4 area of water conservation, determine the various functional areas of soil erosion prevention and control of system layout, the direction of land use, for once during planning of soil and water conservation and soil erosion prevention and control system of the course layout provides the scientific basis.
