摘　　要：AGNPS模型是美国研发的用于模拟小流域土壤侵蚀、养分流失和预测评价农业非点源污染状况的计算机模型。介绍了AGNPS模型的结构、输入输出变量、适用范围,概述了AGNPS模型在美国、欧洲、澳洲和我国南方地区的应用结果。AGNPS (Agricultural Non-point Source) model is a computer model for predicting soil loss and nutrient loading,and evaluating agricultural non-point source pollution at small watershed scale.AGNPS structure,input and output variable parameters,its application scope are described.It is also evaluated simulated results of application of AGNPS to the United Sates,and overseas as well as the South China.The simulated results indicated that AGNPS model could be suitable to use in different regions of the world and the South China.
