%X The present study aims to discuss the export mechanism for nonpoint source pollution of nitrogen from paddy field in Sanjiang Plain.Different scales of in-situ experiments were performed to study the concentrations of nitrogen,the intercepting ratio of bund to nitrogen,and the lateral seepage velocity during the export process of nitrogen in the field-bund-trench system.The annual export load of nitrogen was also quantified.The results showed that the width of near-trench bund affected the lateral seepage v...
