密云水库周边水土保持与水源保护探讨

Soil and water conservation and water source protection in areas around Miyun reservoir

根据密云水库周边自然地理特征和社会经济情况,特别是连续干旱导致水库水位急剧下降、水库周边形成大面积裸露地的现状,分析水库周边人口资源环境的突出矛盾和生态环境存在的主要问题,对密云水库周边水土保持和水源保护思路和措施进行了探索,提出生态建设总体思路和原则,和以库北库区裸露地治理与保护,入库口裸露河滩地治理与保护,以及小型分散点源污染治理为重点的具体措施,同时对加强水库周边的水土保持与水源保护提出政策及管理措施建议。

According to natural geographic characteristics and social economic conditions of the areas around Miyun reservoir, especially the circumstances of water level declined rapidly and large area of bare land occurring due to continuously drought, whose key contradictions are analyzed, which include populations, resources and environment, and the problems existing in the ecological environment of the vicinity of the Reservoir. The thoughts and measures of soil and water conservation and water source protection are probed into, and the general ideas and principals of ecological construction are put forward. Three measures are introduced, which include bare land treatment and protection in northern area of Reservoir, bare flooding land treatment and protection at entrance of Reservoir, and small scattered point source pollution treatment. At last, the management measures and policy on enforcing soil and water conservation and water source protection around Miyun reservoir are brought forward.
