摘　　要：结合"引温济潮"工程的实施,对受水区地表水的监测显示现状水体为富营养状态,有机物污染较为严重。根据研究区污染物负荷的调查,潮白河顺义城区段水环境主要污染源是非点源污染,其产生的主要污染物全年排放量分别为CODCr 213.29 t、总氮80.21 t、总磷9.98 t,按照贡献大小排序为农田径流>农村生活污水>城区径流。根据潮白河顺义段水环境污染成因分析,笔者提出了非点源污染防治控制的对策和建议。With the strengthened control of point source pollution, the non-point source pollution gradually becomes the major parts of pollution in rivers. The pollutants load investigation in Chaobai River （Shunyi New Town） shows that the non-point pollution source is the main pollution source. The CODCr is 213.29 t, TN is 80.21 t and TP is 9.98 t in total water intake area annually. The inputs of nitrogen and phosphorus in agricultural runoff could accelerate the eutrophication of surface waters. Based on the impacts of non-point source pollution on river ecosystem, some countermeasures are put forward to control water pollution.
