摘要

[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 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.
