根据面源污染的过程机理、来源途径和成因分析，针对辽河源头区水资源短缺、农业生产方式粗放、坡耕地较多的特点，通过设置坡地面源试验小区的方法，重点研究坡耕地面源污染物源头控制和途径控制对污染物的截留效果。研究认为退耕还林、退耕还草是从污染途径上控制面源污染的最佳技术，同时从农药和化肥减量化等源头控制角度加以辅助，最大限度降低坡地面源对地表水环境的影响。

The thesis according to the analysis of process mechanism, ways and causes of non-point source pollution, according to the characteristics of water shortage in source of Liao River, extensive mode of agricultur-al production, more extensive of the sloping farmland.The thesis experiments the plot through the establishment land on slopes surface source, to test the effect through cutting off the pollution of source control and way control of non-point source pollution of the sloping farmland , The thesis concluded that the project of returning farm-land to forest and grass, is the best technique for the control of non-point source pollution from pollution on the way.The thesis assists the reduction of pesticides and fertilizers and other source control.The thesis minimizes the influence from non-point source pollution of the sloping farmland to surface water environment.
