摘要
SWAT模型取用水模块针对美国实际情况设定,不能实现不同年份各月动态输入,在我国受强烈人类活动影响的流域其应用受到限制.本文在深入了解SWAT模型结构和模型运行的内部机制,明晰各类输入、输出文件格式和空间运行单元组织方法的基础上,对模型源代码进行修改,完成模型输入、输出文件(TxtInOut)中.wus内取用水设置的追加和修改,反映模型模拟子流域在不同年份、不同月份用水量的差异.同时,针对SWAT模型中设定的水库基本特征参数值范围较小,不符合我国的实际情况,本研究对参数值输入范围进行扩展,使其符合我国的实际情况.将修改后的模型在漳卫南运河流域进行应用,取得了较好的模拟效果.本文在SWAT模型改进和完善上做了有益的探索和尝试,并在人类剧烈影响流域水量水质的模拟中得到了应用,为漳卫南运河流域水资源水环境管理提供了有力的支撑工具.
Application of SWAT model is restricted in river basins influenced by intensive human activities,since water use module in SWAT is postulated in United States,and the monthly input in different years can not be changed.Therefore,the source codes of SWAT model were modified on the basis of the mechanism of SWAT model,input and output file formats,and the organization methods of spacial operation units,and modification for water use module was made for the file of.wus in input and output file（TxtInOut）.The accuracy of SWAT has been improved with the realization of water use diversity among different years and months within sub-basins.Meanwhile,the range of reservior parameter values integrated in SWAT model,which were too small to fit the cases in China,was revised as well.The modified model was applied to the Zhangweinan River basin.Attempt was made to improve the performance of SWAT model,and application was made to simulate water quantity and quality in river basins intensely influenced by human activities.The results could provide the scientific basis and technical support for environmental protection and sustainable uses of water resources in the Zhangweinan River basin.
