摘　　要：生态拦截沟渠是应对农田非点源污染的有效策略。以嘉兴市善县3处农田为研究对象,根据当地农业生产状况和生态条件,设计了一种以生态拦截为核心机制的沟渠结构,通过对该沟渠末端不同时间节点排水中氮磷含量的监测,验证了生态拦截沟渠在农田非点源污染控制中的有效性,结合监测结果提出了意见与建议。Ecological interception ditch is an effective strategy to deal with non-point source pollution in farmland.Taking three farmlands in Shanxian County of Jiaxing City as experimental objects,a ditch structure with ecological interception as the core mechanism was designed according to local agricultural production and ecological conditions,and the nitrogen and phosphorus content of drainage at different time nodes at the end of the ditch was monitored.The effectiveness of ecological interception ditches in farmland non-point source pollution control was verified,and suggestions were put forward based on the monitoring results.
