摘　　要：为了准确评价山东省枣庄市薛城区西部浅层地下水的水质状况,采集11组地下水样,综合使用数理统计分析与图解法探究研究区地下水的化学组分来源及特征,引入方差最大化原理改进物元可拓法评价研究区地下水的水质,并与模糊综合评价法进行对比。结果表明:研究区浅层地下水以微咸水和淡水为主,离子含量从高到低的顺序为HCO_(3)^(-)、 SO_(4)^(2-)、 Ca^(2+)、 Cl^(-)、 Na^(+)、 Mg^(2+)、 K^(+),地下水主要类型是SO_(4)-Ca型;氯碱指数显示研究区存在正向与负向阳离子交换作用;研究区北部水质状况良好,南部水质较差;改进物元可拓评价法比模糊综合评价方法评价更能反映研究区的地下水质真实情况。To accurately evaluate the water quality of shallow groundwater in the west area of Xuecheng District,Zaozhuang City,Shandong Province,11 groups of groundwater samples were collected,and mathematical statistical analy-sis and graphic method were comprehensively used to explore the source and characteristics of the chemical components of groundwater in the study area.The principle of variance maximization was introduced to improve the matter-element extension evaluation method to evaluate the water quality of the study area,which was compared with the fuzzy compre-hensive evaluation method.The results show that the shallow groundwater in the study area is mainly brackish water and fresh water,and the order of ion content from high to low is HCO_(3)^(-),SO_(4)^(2-),Ca^(2+), Cl^(-), Na^(+), Mg^(2+), K^(+),and the main type of groundwater is SO_(4)-Ca type.The chlor-alkali index shows that positive and negative cation exchange exists in the study area.The water quality in the northern part of the study area is good,and that in the southern part is poor.The improved matter-element extension evaluation method can better reflect the real situation of groundwater quality in the study area than the fuzzy comprehensive evaluation method.
