摘　　要：植被拦截是控制非点源污染的最佳管理措施之一。为了探讨植草沟与湿地滞留塘组合系统对农田径流污染控制效能,研究以江苏金坛市某农业科技园为对象,对农田降雨径流特征进行了现场测试,并通过相关性分析对农田径流各污染物相互关系及成因进行了探讨。考察了4场典型降雨下植草沟-湿地滞留塘组合系统对农田径流污染实际控制效能,结果表明植草沟-湿地滞留塘组合系统是控制农田径流污染的有效措施。Vegetation interception technology is one of best management practices for the control of non-point pollution. For investigating the pollution control efficiency of grassed swales and wetland detention ponds system,a agricultural science and technology park was chosen as the research area which located in Jintan City, Jiangsu Province. Characters of farmland runoff pollutants were studied and the relationship between main farmland runoff pollutants and its causes were discussed by correlation analysis. In addition, removal efficiency of farmland runoff pollutants by the combination of grassed swales and wetland detention ponds were studied under four typical rainfalls. Results showed that combined system of grassed swales and surface flow wetland were effective measures in farmland runoff pollutants control.
