中文摘要：

地下水是为在北方中国的人的消费的一个主要自然资源。为在这个区域喝，农业灌溉，和工业使用欣赏深地下水的适用性是必要的。到这个目的， 47 件地下水样品的一个总数从学习区域被收集；由把不同 hydrochemical 变量的集中与优秀的标准值作比较，可变模糊集合(VFS ) 被使用分别地为各种各样的目的计算地下水质量索引(GQI ) 。后来， GQI 空间分发地图用一个地理信息系统(GIS ) 被构造描出的工具地下水质量的空间变化。在这案例研究， GQI 空间分发地图表明区域为改变目的由最大的可允许的地下水盖住(喝酒，灌溉，并且工业) 是 1377.2；2354.7；并且 3854.8 km2 分别地。在学习区域的东方部分的地下水对喝合适，与象灌溉水来源的西南的区域；全部学习区域为使用在是可接受的工业，除了 Jiaozuo 的西方的部分城市。因此， GQI 空间分发地图能为更好持续的地下水资源管理为非技术的决定制造者提供有用信息。

英文摘要：

Groundwater has been a major natural resource for human consumption in north China. It is necessary to appreciate the suitability of deep groundwater for drinking, agricultural irrigation, and industrial uses in this region. To this end, a total of 47 groundwater samples were collected from the study area; by comparing the concentrations of different hydrochemical variables with quality standard values, the variable fuzzy set （VFS） was applied to calculate the groundwater quality index （GQI） for various purposes, respectively. Afterward GQI spatial distribution maps were constructed using a geographic information system （GIS） tool to delineate spatial variations of groundwater quality. In this case study, the GQI spatial distribution maps reveal that the areas covered by ＂Maximum Permissible＂ groundwater for varying purposes （drinking, irrigation, and industrial） is 1377.2; 2354.7; and 3854.8 km2, respectively. The groundwater in the eastern part of the study area is suitable for drinking, with the southwestern region as the irrigation water source; the entire study area is acceptable for use in industrial, except the western part of Jiaozuo City. Therefore, the GQI spatial distribution maps can provide useful information for non-technical decision makers for better sustainable groundwater resources management.
