摘要
对于干旱地区来说,地下水水质评价是一项重要而必要的工作,其评价结果为当地的地下水资源开发利用保护提供科学依据。本文通过对新疆塔里木盆地162个地下水水样测试结果的分析,应用5元联系度的熵权集对分析法对研究区地下水水质进行评价。通过不同评价方法的比较分析发现,熵权集对分析法评价结果客观,计算简单、方便等优点,是一种有效的地下水水质评价方法。评价结果表明,巴州地区、塔里木河流域、开孔河流域的地下水水质较其他地区和流域差,阿克苏地区、阿克苏河流域、渭干河流域的地下水水质总体水平较好。
The evaluation of groundwater quality is important and essential work for arid areas. The evaluation results can be applied as the scientific basis for reasonably exploiting and protecting the water resources. 162 groundwater samples were collected from Tarim basin in Xinjiang, and the set paired analysis based on entropy weight was applied in order to evaluate the quality of the groundwater with five- demarcation connection degree. Compared with the different evaluation methods, it is found that the set paired methods based on entropy weight could provide the more authentic, straightforward and more convenient results. So it is an effective method to assess the groundwater quality. The resuhs show that the groundwater quality in Bazhou region, Tarim river basin and Kaidu-Kongque river basin is less optimistic than other regions and river basins. The general groundwater quality in Aksu region, Aksu river basin and Weigan rivef＇~oasin is better.
