摘　　要：以漓江支流小流域作为非点源污染流域研究对象,应用简化的SWAT模型,模拟示范区流域非点源污染负荷量。根据模型模拟结果,预测流域内污染物的主要来源是当地农药化肥的施用。根据地表水环境质量监测标准,对流域内水质作出分析,提出减少污染负荷量的方案以及削减策略,为制订示范区内非点源污染的控制策略提供合理的依据。Small watershed of tributaries which belongs to the Lijiang River were selected as the research object of non-point source pollution in this paper. And the thesis used simplified SWAT model to simulate the loading capacity of non-point suorce in demonstration area. According to the results of the model,it predicted the main source of pollutants in the river basin in the application of local pesticides and chemical fertilizers. By the stand-ards of monitoring for surface-water environmental quality, water quality in river basin was analyzed. The scheme to reduce the pollution loading and reduction strategies were put forward and offered reasonable basis for the con-trol strategy of non-point source pollution in demonstration area.
