中文摘要	以2013年在陕北定靖中部地区采集的62组地下水水样的全分析测试结果为数据基础,分别用单指标评价法、内梅罗指数评价法、层级阶梯评价法和模糊综合评价法对地下水进行质量评价,并对评价结果进行综合加权平均,以期得到更加可靠的质量评价结果,旨在为该地区地下水资源的合理开发利用与保护提供依据。评价结果显示,Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ类水所占比例分别为3.23%、 11.29%、9.68%、24.19%、51.61%,约75%的地下水不适合直接饮用;该区地下水质量较差。水质整体分布规律为:东北部沙漠平原地区水质较好,西南部黄土丘陵地区水质差;在局部,油气井开采较密集和芦河周围地区水质较差,说明原生环境和人类活动是造成该区地下水质量差的两个主要原因。
英文摘要	Based on the test results from 62 groups of groundwater samples in the central Dingjing area in the northern region of Shannxi Province in the year 2013,the single factor index evaluation method,the Nemerow index evaluation method,the hierarchical evaluation method,and the fuzzy comprehensive evaluation method were used to evaluate the quality of groundwater in the study area. Comprehensive weighted averaging of the evaluated results was carried out in order to obtain results that were ultimately reliable,providing a basis for the rational development and protection of the groundwater resources in this area. The evaluation results show that groundwater of grades I,II,III,IV,and V accounted for 3.23%,11.29%,9.68%,24.19%,and 51.61%,respectively, and about 75% of groundwater was not suitable for drinking. The overall quality of groundwater was poor in the study area. The groundwater quality was good in the northeastern desert-plain area and poor in the southwestern loess hilly area. In addition,the groundwater quality was poor in the densely-mined oil and gas well areas and around the Luhe River,indicating that the primitive environment and human activities are two main factors of poor quality of groundwater.
