【摘要】 针对我国非点源污染模型应用研究的需要,本文系统地介绍了SWAT模型的原理及其数据准备与处理过程,对模型的空间参数化、研究流域的空间离散化以及结合GIS建立流域基础信息库管理和输入模型所需数据等工作进行了简要说明.最后对SWAT模型的应用情况和研究前景做了总结与展望.更多还原

【Abstract】 Demanding for the study of Non-point source pollution in our country,this paper introduces the SWAT model principle and its data preparationses and disposal process systematically.It has briefly illuminated that we how to use the model spatial parameterization,the study watershed spatial discretization and to combine GIS with this modle to establish the watershed foundational database.Finally,there is a expectiation of the SWAT model in applied circumstance and study foreground.更多还原
