摘　　要：非点源污染是继点源污染之后的又一重要的环境污染方式。四川省境内农村水源水质保障堪忧,湔江流域的非点源污染已严重影响了彭州市的饮用水安全。因此,正确地掌握湔江污染物来量,合理评价湔江水质及水环境质量,对保障彭州市居民饮水安全、维护彭州市社会稳定具有重要作用。本文构建了湔江流域ArcSWAT产流、产沙及污染物输出模型,对湔江流域进行了分析、模拟,结果显示ArcSWAT模型对湔江流域产流、产沙及污染物输出模拟具有较高的适用性。此外,为改善湔江流域和西河水库的水质水环境提出了建设性意见。Non-point source pollution is another important way of environmental pollution after point source pollution.The water quality of rural water sources in Sichuan Province is worrying.Non-point source pollution in the Xujiang River basin has seriously affected the safety of drinking water in Pengzhou City.Therefore,it is important to correctly grasp the amount of pollutants coming from the Xujiang River and reasonably evaluate the water quality and water environment quality of the Xujiang River to ensure the drinking water safety of Pengzhou residents and maintain the social stability of Pengzhou City.In this paper,the ArcSWAT model of runoff,sediment yield and pollutant output in the Xujiang River basin is firstly constructed,and then the model is analyzed and simulated.The results show that the ArcSWAT model has high applicability in the simulation of runoff,sediment yield and pollutant output in the Xujiang River basin.In addition,constructive suggestions are put forward to improve the water quality and water environment of the Jiujiang River basin and Xihe Reservoir.
