| 摘 要： | 农业非点源污染是造成我国流域污染的主要原因之一,而数学模型是研究流域污染、水质分析与预测的主要技术手段。在综合分析目前非点源污染模型的优缺点后,选取当前较为先进和完善的分布式水文模型——SWAT模型,借助GIS、RS技术,开展洱海流域农业非点源污染模拟研究,了解洱海流域农业非点源污染状况,为洱海流域的综合治理和规划提供合理的参考和依据。

| Abstract: | Agricultural non-point source pollution is one of the major reasons,which causes watershed pollution in China.However,mathematic model is an important tool in the research of watershed pollution,water quality analysis and forecast.After synthetically analyzing the advantages and disadvantages of non-point source pollution at present,the more advanced and perfect distributed hydrological model—SWAT model was selected,using GIS and RS technology,the study on agricultural non-point source pollution simulation in Erhai Lake Watershed was carried out,and non-point source pollution condition was understood to provide a reasonable reference and basis for the comprehensive management and plan of Erhai Lake Watershed. |
