摘　　要：对福建省晋江市地下水布点采样、水质检测,运用单组分和综合得分评价研究区地下水环境质量,通过GIS结合地统计分析方法———普通克吕格插值法,进行评价结果插值运算,表征点状离散数据向面状连续数据转换,在评价结果重分类基础上绘制环境质量三维DEM等值线图,得出晋江市地下水环境质量包含(Ⅰ、Ⅱ、Ⅳ、Ⅴ)四个等级,处于Ⅰ、Ⅱ级(优良水平)占全区81.67%,处于Ⅳ、Ⅴ级(较差、极差水平)的地区主要分布于安海镇—东石镇交界、磁灶镇和陈埭镇,主要为TDS、Cl-、NO-3、NO-2、NH+4因子超标,分析与海水入侵,农业生产,工业、生活污水排放有关,为有效防治研究区地下水污染提供指导建议.This paper tests groundwater samplings in Jinjiang City, studies the groundwater environmental quality of single component and the comprehensive score evaluation of the study area, using GIS combined with geo-statistical analysis method the ordinary Kriging interpolation, the evaluation results of interpolation point, characterization of discrete data to planar continuous data conversion. Evaluation results of three-dimensional DEM contour map based on the environment quality classification,environmental quality of groundwater include （Ⅰ、Ⅱ、Ⅳ、Ⅴ） four ranks in the city of Jinjiang,in Ⅰ,Ⅱ ranks （excellent level ） reached 81.67 percent ,in IV, V ranks （ poor or bad level ） area mainly is distributed in Anhai town to Dongshi town at the junction, Cizao town and Chendai Town, those exceed the standard are TDS, CI-, NO3- , NO2- , NH＋ , analysis and seawater intrusion, agricultural production, industrial sewage, domestic sewage, provide guidance for effective prevention and control of groundwater pollution in this area.
