摘要
在简要介绍非点源污染SWAT模型发展历程的基础上,论述模型数据处理及数据库建立过程,从模型适用性、参数敏感性及模型改进方面分析了模型应用研究现状,指出应在模型参数获取、减小模拟误差和短期污染过程模拟等方面加强研究以提高SWAT模型应用于非点源污染的研究水平。
Control of non- point source pollution which with completed mechanism is an important problem be faced in water resources management,the simulation of Water Pollution model is an important tool in research of non- point source pollution,and it's also the effective and direct method in quantitative research,impact evaluation and pollution remediation. This paper introduced the development,data processing and database establishing of SWAT,analyzed application and research status in terms of model applicability,parameter sensitivity and model improvement,pointed that should strengthen research in obtaining the model parameters,reducing simulation errors and short-term pollution process simulation,regarding to improve the research level of the non- point source pollution.
