摘　　要：镇江市上社河为农田区域排水灌溉河道,承担着容纳农田面源污染负荷的作用。为改善区域水环境质量,通过截污围隔装置、组合型生态浮床、生态护坡及水生植物恢复等工程技术措施对该水体进行生态修复治理。结果表明,经过6个月的稳定运行,水体中的氮、磷等污染物质得以有效去除,水生态系统的结构和功能得到了恢复和提升。该工程设计可为农村面源污染水环境生态修复的相关应用提供参考。Shangshe stream in Zhenjiang is a farmland drainage and irrigation river, which is responsible for agricultural non-point source pollution load. In order to improve the water environment, ecological restoration techniques, such as the sewage interception project, combined ecological floating bed technology, ecological slope and hydrophyte restoration, were taken to treat the water. After the operation of six months, nitrogen, phosphorus and other pollutants were removed effectively from the water, the structure and function of water ecosystem was recovered and promoted, which provides a good reference for the ecological restoration projects of water environment regarding rural non-point source pollution.
