摘　　要：鄱阳湖区农村面源污染问题日益严峻,已威胁到湖泊的水环境安全。结合该区域农村面源污染自身的变化特征,在星子县示范区内构建结构性最佳管理措施BMPs(best management practices)系统对区域内农村面源污染进行控制。结果表明,在监测期间该BMPs系统对COD,TP和TN的削减量分别为568.25,3.06和26.90kg。其中人工湿地对COD,TP和TN的单位面积削减量约达40,0.4和3.0g/m2,有较稳定的污染物去除能力;生态沟渠对各污染物单位面积削减量变化较大,与人工湿地相比虽有更强的污染物削减能力,但稳定性较弱。结合生态沟渠和三级表面流人工湿地的特点,建议通过引入适宜的植物至生态沟渠提高其处理污染物的稳定性。Water environment security in rural areas around Poyang Lake has been threatened by increasingly severe non-point source pollution（NPS pollution）.Combined with the features of NPS pollution in the areas,the structural best management practices（BMPs） are established in the demonstration area of Xingzi County to control the rural NPS pollution.Monitoring results show that in the monitoring period,the removal amounts of COD,TP and TN by the BMPs are 568.25,3.06 and 26.90 kg,respectively.Constructed wetland maintains the better and more stable pollutant removal capability and the removal amounts of COD,TP and TN per unit area are about 40,0.4 and 3.0 g/m2,respectively.The removal amounts of the pollutants per unit area by ecological ditch vary greatly.Ecological ditch has better removal ability per unit area than constructed wetland,but has poor stability.In consideration of the advantages of ecological ditch and tri-class surface flow constructed wetland（3-SFW）,the plants suitable to ecological ditch are recommended to improve its stability in pollutant removal.
