四种地下水水质评价方法的应用对比分析——岷县城乡供水水源地

The Application and Comparison of Four Methods in Groundwater Quality Assessment——Water Supply source of the Urban and Rural for Minxian

选择单因子评价法、F值综合评价法、模糊综合评价法和集对分析法等四种地下水水质评价方法对岷县南部和西部的15个农村供水水源地进行水质评价,得出相应的评价结果,各种评价方法得出的评价结果进行对比分析,并综合各评价方法的优缺点。四种评价结果表明:岷县南部和西部15个城乡供水水源地地质80%不达标,经相关处理后才可作为生活饮用水源。为该地区其后同类供水水源地的水质评价及防治污染提供了科学的依据。

The article assessed the groundwater quality of fifteen rural water sources in south and west of Minxian using four kinds of methods which are single factor evaluation method, F value of comprehensive evaluation method, Set Pair Analysis Method and the fuzzy comprehensive evaluation method . This paper concluded the advantages and disadvantages of each method according to the comparison and analysis of each evaluation result. The evaluation results will provide a scientific basis for water quality assessment of water supply sources and prevention--control of pollution in this region.
