摘　　要：[目的]研究滇池流域大河水库水源保护区面源污染控制方案。[方法]以2010年SPOT5卫星遥感影像和野外调查GPS记录为数据源,对滇池流域大河水库水源保护区进行基于面源污染控制的生态设计,并通过各土地利用类型的N、P输出量变化来评估优化措施对面源污染物的削减效果。[结果]优化后,水源保护区控制土壤侵蚀和N、P等污染物排放的功能得到提升,优化措施对水源保护区面源污染的防控具有显著效果。[结论]该研究为促进滇池流域大河水库水源保护区绿色小流域生态建设提供了科学依据。[Objective] The research aimed to study control scheme for nonpoint source pollution in Dahe Reservoir water source protection area of Dianchi Lake basin.[Method] On the basis of the SPOT5 satellite remote sensing imagery in 2010 and field investigation of GPS record,ecological design for nonpoint source pollution control in Dahe Reservoir water source protection area of Dianchi Lake basin was conducted.Then,the effects of the optimization measures were evaluated by the reductions of N and P outputs on different land-use types.[Result] Control functions of the water source protection area on soil erosion and the emissions of N,P and other pollutants would be promoted after optimization.The optimization measures had a significant effect for prevention and control of the non-point source pollution in the water source protection area.[Conclusion] The research provided scientific basis for promoting ecological construction of the small green basin in Dahe Reservoir water source protection area of Dianchi Lake basin.
