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 mech-anism 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 farm-land non-point source pollution control was verified,and suggestions were put forward based on the monitoring results.
