摘　　要：地下水水质具有区域空间分布的特征,本文以内蒙古临河市浅层地下水为研究对象,根据地下水水质调查分析结果,利用水质卫生综合指数法对采样点地下水水质进行综合评价,利用ArcGIS的地统计空间分析功能,对评价结果数据进行分析,选择合理的插值方法,得到研究区地下水水质的空间分布图,结果表明:1级水占25.14%,主要分布在研究区东南部和西南部;水质差(4、5级水)的区域主要分布在研究区的北部及中部部分地区,约占研究区总面积的54.42%.最后探讨了GIS在区域地下水水质评价中的优势及存在的问题.Groundwater quality has the character of regional spatial distribution, this study studied the shallow groundwater in LinHe district in NeiMenggu province, assess groundwater quality by using water quality sanitary comprehensive index, then analysed the result of assessment, selected the interpolation method to applied to map the groundwater quality. Obtained results show that the grade, one water sources account for 25.14%, it is mainly in south-west and south-east of the study area; the grade four or five water sources is mainly in north of the study area, it account for 54.42%. Finally, the paper discussed the advantages and the existing problems of GIS using in the regional groundwater quality assessment.
