摘　　要：地下水化学类型是水化学组成及其环境的表征,也是地下水质量评价的重要部分。利用某地区水文地质调查采集的检测数据,采用舒卡列夫分类法和阿列金分类法进行了地下水化学类型的分类,确定了研究区水化学类型以HCO3-Ca型为主;在此基础上选择模糊聚类分析法进行了水化学类型的分类和研究。结果表明:传统分类法可反映研究区地下水优势离子,确定地下水水化学类型,但无法解决归类特性所产生的分类不合理问题;模糊聚类分析法有效克服了传统分类法的弊端,可全面反映水样间的亲疏关系和相似程度,将研究区水化学类型细分为5类,更好地体现不同水化学类型间化学组分的含量特征。Groundwater hydrochemical type is characterization of hydrochemical composition and environment,also an important part of the groundwater quality evaluation.This paper classified groundwater hydrochemical type according to Shukaliefu classification method and O.A.Arliekin classification method using hydrogeology survey data,and identified the mainly hydrochemical type is HCO3-Ca of the study area.Based on that,the paper classified and researched the hydrochemical type by using fuzzy clustering analysis method.The result shows that the traditional classification method can better reflect the advantage ions of groundwater and determine the hydrochemical type,but can not solve the irrationality problem generated from classification characteristics.However,fuzzy clustering method not only overcomes the disadvantages of traditional classification method effectively,but also fully reflects the relationship and similarity degree of hydrochemical composition.Classifying the hydrochemical type of the study area into five ones,it reflects the characteristics of the content of chemical components of different hydrochemical types better.
