摘要
针对污染物特征认知不足导致的模型可靠性差问题,提出农村流域非点源污染时空规律量化分析模型。以目标流域的实际土壤环境和气象环境为依据,设计包含土壤物理数据、化学数据和气象数据的模型数据库,处理、加载相关数据,建立包含子流域的河网SWAT时空规律量化分析模型,完成初次模拟,将数据库中的数据转变为输入文件,输入到模型中,输出结果即为时空规律分布结果。实验结果表明设计的农村流域水非点源污染时空规律量化分析模型参数敏感性高、数据拟合度高,模型可靠性得到了提高。
To solve the poor reliability of analysis model caused by insufficient cognition of pollutant characteristics,a quantitative analysis model of spatiotemporal law of non-point source pollution in rural watershed was proposed.Based on the actual soil environment and meteorological environment of the target watershed,the model database including soil physical data,chemical data and meteorological data was designed.The relevant data were processed and loaded,the quantitative analysis model of SWAT spatial-temporal law of river network including sub watershed was established.The initial simulation was completed,and the data in the database was transformed into input file and input into the model.The output is the result of spatial-temporal distribution.The experimental results show that the designed quantitative analysis model of non-point source pollution in rural watershed has high sensitivity of parameters,high degree of data fitting and improved reliability of the model.
