熵权集对分析法在地下水水质评价中的应用

Application of Set Pair Analysis Method Based on Entropy Weight in the Groundwater Quality Evaluation

在介绍集对分析法基本原理的基础上,详细论述了熵权集对分析法在水质评价中应用的具体步骤,并以内蒙古东胜煤田阿不亥普查区地下水为例进行水质评价.结果表明,该地区地下水水质较好,未受污染或污染很小.熵权集对分析法具有使用方便,计算简单,信息利用率高,结果直观、合理、可靠等优点,是一种高效的地下水水质评价方法,值得推广.

After brief introduction of the principle of Set Pair Analysis method, visualized steps of Set Pair Analysis in water quality assessment were explained in detail, and were applied in the Dongsheng coalfield in Erdos, China, and satisfactory results were obtained. Assessment results indicated that groundwater qualities in study area were relatively good, Set Pair Analysis method which was an optimal method for groundwater quality assessment and worth promoting was easy to use, and calculation processes which use almost all the relative information was simple, results were reasonable, reliable and intuitive.
