SWAT模型在新蔡河流域面源污染研究中的应用OA
Application of SWAT Model in the Study on Non-point Source Pollution in Xincai River Basin
[目的]应用SWAT模型对新蔡河流域的径流、泥沙及面源污染负荷的产输出过程进行模拟计算.[方法]首先介绍了SWAT模型的原理,然后对模型径流参数和水质参数进行率定和验证,最后利用SWAT模型研究新蔡河流域的泥沙及面源污染负荷的产输出特性.[结果]SWAT模型基本合理可行,可用于新蔡河流域面源污染的模拟计算.模拟结果表明,丰水年泥沙和各种面源污染物负荷都比较大,平水年次之,枯水年最小,这说明泥沙和面源污染的产输出与当年的降雨径流量有关.[结论]该研…查看全部>>
[ Objective] The study aimed to simulate the producing and transporting process of flow, sediment and non-point source pollution in Xincai River basin based on SWAT model. [ Method] On (he basis of analyzing the principles of SWAT model, the correlative parameters of flow and water quality were calibrated, then the spatial and temporal distribution of flow, sediment and non- point source pollution in Xtncai River basin were studied using the SWAT model.
