摘　　要：联合应用流域非点源AnnAGNPS模型和水库水质CE-QUAL-W2模型,研究了非点源污染对陕西省金盆水库水质影响。利用AnnAGNPS模型输出黑河流域非点源污染负荷,将其转化为金盆水库入库浓度作为CE-QUAL-W2模型的输入,对黑河金盆水质进行预测。结果表明:(1)非点源污染在洪水期时对金盆水库水质有较大影响,而在非洪水期时非点源污染对水库水质影响不显著;(2)非点源污染对水库纵向和垂向水质的影响存在差异性;(3)林地对流域非点源污染的削减起到很大作用;(4)在对水库水质进行预测时,应对洪水期和非洪水期的非点源污染区别对待。The watershed non-point pollution model AnnAGNPS and water quality model CE-QUAL-W2 were integrated to apply.Outputting the non-point source pollution loads based on AnnAGNPS model and converting the loads as the inputs of CE-QUAL-W2 model,this paper attempts to predict the water quality of Jinpen reservoir and study the impacts of the non-point source pollutions on water quality.Results show that：（1） non-point source pollutions have greater impacts on water quality of Jinpen reservoir in the flood period than in the non-flood period;（2） the impacts of non-point source pollutions on water quality make a great difference between longitudinal and vertical water qualities;（3） forests play a significant role in the reduction of non-point source pollution in the watershed;（4） when predicting the water quality of reservoir,non-point source pollutions should be treated differently in the flood and non-flood periods.
