中文摘要	在中国东南丘陵山区一中尺度流域———九龙江流域选取4个土地利用方式不一的典型小流域,借助GIS和相关资料率定模型参数,并通过对2003年4月至9月各小流域出口降雨水质水量的同步监测,检验了连续分布式参数模型(AnnualizedAGriculturalNonPointSourceModel,AnnAGNPS)的适用性.研究结果表明,模型对于地表径流量的模拟能力好于对泥沙和营养盐的模拟,对总磷和泥沙输出的模拟结果表现出了较大的不确定性.; An interface, in which ArcView Geographic Information System(GIS) was integrated with Annualized Agricultural Non-Point Source Model (AnnAGNPS), was used as a procedure to input, analyze, and visualize spatial data that agricultural Non-point source pollution concerned. Four typical sub-watersheds in southeast of China were chosen to test AnnAGNPS model from storm evens during the period of April to September, 2003. Then, the model was run to simulate the annual runoff, sediment and nutrient yield. The simulation results show that the event flows and nitrogen exports were simulated efficiently with AnnAGNPS, but only moderate accuracy is achieved for prediction of event-based sediment yield and phosphorus exports, especially the prediction of sediment yield and total-phosphorus show obvious uncertainties.; 福建省科技重大攻关项目(No.2002H009)~~
