摘要
在介绍地下水质量评价方法优缺点的基础上,分析了建立可拓评价模型的一般方法.探讨了该模型在水环境评价中的应用.根据简单关联法的多前提性,提出层次分析法的可拓评价的改进方法.结合榆神府矿区的水环境的实际资料,对其1,2期进行了改进可拓评价.结果表明:大柳塔、神木县的水环境最差,接近5类水;榆林市的普惠和河口水库南部次之,为4类水;在大保当等地区的地下水为3~4类水之间;在解家堡等处的地下水为2类水;榆林市南部等地是水环境最好的地区.
According to multi-condition of association method, refined Ketuo method based on AHP was presented.Combined with the real data of Yushenfu Coalmine, groundwater environment of installment and dichophase in Yushenfu was evaluated. The results show that the water environment in Daliuta and Shenmu county is worst, and belong to 5 type water, and Puhui in Yulin city and Hekou reservoir take second place and belong to 4 type water,and those in Dabaodang area belong to 3 - 4 type water. The water environment in Xiejiabao is better and belongs to 2 type water, the water environment in southern Yulin is best and can be used in every kinds of application.
