摘　　要：目前采用SWAT(Soil Water Assessment Tool)模型可预测大流域、复杂多变的土壤类型,进而对应明确土地利用方式与管理措施条件,长期影响地方土地水分、泥沙以及化学物质变化状况。主要利用SWAT模型对湖南省沩水流域的农业面源污染情况进行模拟,提出模型应用要点,了解其模拟适用性,并最终合理分析沩水流域年径流量推算成果。At present,SWAT(Soil Water Assessment Tool)model can be used to predict large watershed,complex and changeable soil types,and then to clarify land use patterns and management measures conditions,which will affect the changes of local land moisture,sediment and chemical substances for a long time.In this paper,SWAT model is mainly used to simulate agricultural non-point source pollution in Weishui watershed of Hunan Province.Key points of application of the model are put forward to understand its applicability,and finally,the calculation results of annual runoff in Weishui watershed are reasonably analyzed.
