摘　　要：如何对非点源污染进行科学认识与有效控制已经成为流域污染防治的重要课题之一,不合理的土地利用方式是造成非点源污染的关键驱动因子。以四川省黑水河流域为研究区域,基于GIS平台建立了流域下垫面空间数据库,应用SWAT模型对黑水河流域及其子流域进行了年径流、泥沙及营养盐输出模拟,从土地利用方式改变对非点源污染影响的角度入手,设计环境保护规划方案,模拟了不同规划方案下黑水河流域的泥沙及营养盐输出情况,可为该流域非点源污染负荷的控制提供实际解决方案。How to scientifically understand and effectively control non-point source pollution has become one of the important topics in river basin pollution prevention and control.Taking Heishui River Basin as the research area,this paper establishes the spatial database of basin underlying surface based on GIS platform,simulates the annual runoff,sediment and nutrient output in Heishui River Basin and its sub-basins through SWAT model,designs the environmental protection scheme from the perspective of the influence of land use change on non-point source pollution,and simulates the sediment and nutrient output in Heishui River Basin under different schemes,which can provide practical solutions for the control of non-point source pollution load in this basin.
