摘　　要：基于SWAT模型对岳城水库流域污染源进行模拟研究。利用流域出口的观台水文站2006—2009年的水量、水质等实测数据对经过校准的SWAT模型进行验证。结果表明:岳城水库流域年均入库非点源污染负荷TN为3 025 t,TP为234 t,年均非点源污染贡献率不足50%;点源污染中,TN以工业点源污染为主,其贡献率达31.9%,TP则以城镇生活点源为主,其贡献率为36%;非点源污染中,农业非点源污染源占主要比重,化肥贡献率最大为16.9%,禽畜养殖污染次之,贡献率为10.5%,农村生活污染最小;非点源污染的主要来源是耕地,TN和TP年均负荷分别达到2.77 kg/hm2和0.397 kg/hm2,模拟成果可为岳城水库水源地保护和流域综合管理提供新的技术方法及科学依据。The pollution sources of Yuecheng Reservoir Basin was simulated based on SWAT（ Soil and Water Assessment Tool） model. A calibrated SWAT model was verified by the measured data of water quantity and water quality of hydrological station in the basin exists in the year 2006—2009. The results show that the average contribution of non-point source was less than 50% with the average annual loadings of TN and TP 3,025 t and 234 t respectively. In the pollution sources,TN,with its contribution of 31. 9%,was mainly from point source pollution of industry,and TP,with its contribution of 36%,was mainly from urban life point source; Non-point source pollution was mainly from agricultural non-point source pollution,with 16. 9% contribution of fertilizer and 10. 5 %contribution of Livestock breeding pollution. Rural domestic pollution was the minimum. The main source of nonpoint source pollution is from farmland,with its average annual loadings of TN and TP 2. 770 kg / hm2 and 0. 397 kg / hm2 respectively. The simulation results can provide a new technology method and scientific basis for water source protection of Yuecheng Reservoir and integrated management of basin.
