四种典型非点源污染模型研究与应用进展

Research and Application Progress of Four Typical Non-point Source Pollution Models

随着点源污染得到控制,非点源污染日益受到重视,采用适当的数学模型进行模拟和分析是研究非点源污染控制最直接有效的方法之一。为此,选择四种典型的非点源污染模型(SWAT、GLWF、SPARROW、HSPF),介绍了模型的来源、功能、原理、结构,并从应用尺度、输入信息、输出信息、优点及局限性等方面进行对比分析,总结了四种模型的应用和改进,分析了同一流域不同模型的应用效果,指出模型选取、自主研发新模型、多技术融合、模型适用性等是今后非点源污染模型研究和发展的方向。

With the control of point-source pollution,more and more attentions were paid to the non-point source pollution.One of the most direct and effective methods for the study of non-point source pollution control is the use of appropriate mathematical models for simulation and analysis.The source,function,principle,and structure of the four typical non-point source pollution models(SWAT,GLWF,SPARROW,HSPF)were introduced.The models were compared and analyzed in terms of application scale,input information,output information,advantages,and limitations.The application and improvement of the four models and the application effects of different models in the same watershed were summarized.Model selection,independent research and development of new models,multi-technical integration,and model applicability studies had been pointed out as the direction for future research and development of non-point source pollution models.
