The Comprehensive Management Study Of Yanqing Dalianshu Eco-clean Minor Watershed

Water as a fundamental human survival, protection of water sources become one of the important part. Small Watershed as an effective measure to protect water sources have been get more and more attention. The haze have been become another major environmental problems after dust storms, environmental issues have become increasingly prominent, need to be solved. Dalianshu minor watershed is the part of the ecological barrier area north of Beijing, play an important role in inhibiting the formation of sand sources and sand invasion.Take Dalianshu minor watershed as the study area. The minor watershed control combine the field investigation with the existing literature, The use of GIS analysis and stability calculation comprehensive analysis the minor watershed occur soil erosion reasons and problems in sewage, garbage, latrines, trench and environmental. The minor watershed mainly has shortcomings of garbage collection facilities, garbage piling chaos, damaged roads and bare slopes and other issues. The main reasons caused soil erosion is human activities on mountain vegetation and natural channel destruction. While take water protection as main objective, combined with the characteristics of different terrain of soil erosion, land use direction, status of human activities, divided into "ecological protection zones, ecological management zones, ecological restoration zones."The principles of Eco-clean minor watershed measures designed adhere to ecological priority and harmony between man and nature. On basis of control of soil erosion, afforestation, landscaping, improve the ecological environment and the quality of environment grade to build "ecological restoration, ecological management, ecological protection," three lines of defense. Meanwhile properly routed measures based on problem analysis and survey findings. Ecological management zones new set stone-faced terraces, trash, village landscaping and other measures to govern. Riverside ecological zones with governance protection, in order to protect water resources, improve water quality.Through the measures to predict benefits and give specific recommendations. Specific content (1) Vegetation coverage will increase by 0.045%,(2) refuse consumptive capacity of new addition 141.44t/a, (3) increased 1.386 million yuan of direct economic benefits, (4) the measures laid simultaneously can effectively control soil erosion, improve the industrial facilities, increase farmers’income and promote sustainable local development, improve the existing problems. Based on the actual local situation suggested that the local strengthen supervision and management, strengthen the integration between projects guarantee Sources of funding continuity of governance and governance conducting.
