The Planning And Design Of Da Changhan Small Watershed Erosion Comprehensive Management In The Loess Plateau

The Loess Plateau is the most serious soil erosion area in China and even the wholeworld. In this study, based on the analysis of typical small watershed comprehensivemanagement scheme, summarized the planning principles, methods and procedures of thecomprehensive management in a small watershed. According to the environment andecological characteristics of the Da changhan watershed which has located in ShaanxiProvince, presented the small watershed planning method and design for the comprehensivesoil erosion control. The study not only provides the basis for comprehensive management ofthe Da changhan watershed, but also provides a reference for the integrated watershedmanagement planning and design for the same region. Achieved the following results:1. Based on the analysis of typical small watershed comprehensive management scheme,summarized the planning principles, methods and procedures of the comprehensivemanagement in a small watershed. Summarized the principles of configuration forcomprehensive management. And small watershed comprehensive management measuresconfiguration mode of slope, the production of road erosion and corrosion measuresgovernance principles, vegetation banned governance measures and methods.2. According to the environment and ecological characteristics of the Da changhanwatershed, prepared the watershed management planning program.3. Based on the overall layout of soil erosion in small watershed comprehensivemanagement，designed the soil erosion control measures in the watershed such as sloping land,wasteland, ravines and small build drainage works.4. Analyzes its benefits to economic, social and ecological after comprehensivemanagement.
