以西南岩溶地下水污染调查评价中广西红水河中下游澄江地区地下水数据为基础，对该地区26件样品的水化学类型、化学成分含量特征、成分间相关特征以及化学成分的空间分布特征及影响因素进行了研究。结果表明：该地区地下水水化学类型为Ca-HCO3型或Ca·Mg-HCO3型；地下水中测试指标背景含量均未超过Ⅲ类水标准；大部分测试指标在该地区地下水中分布较均匀，只有Zn、Se和Hg在局部富集，分布不均匀；该地区地下水中元素含量与pH值没有明显的相关关系，而总硬度、HCO3－、Ca2＋、Mg2＋、K＋、Na＋、SO2－4、NO3－、I －等元素间则显示出一定的相关关系，地下水中起决定性作用的是HCO3－、Ca2＋、Mg2＋；该地区地下水中元素含量空间上具有片状分布特点，主要受地质背景、地理条件和人类活动的综合作用所制约。

Based on the groundwater data obtained from the karst groundwater pollution investigation and eva-luation in Southwest China,geochemical characteristics of 30 elements or indicators on 26 karst groundwater samples which have been analyzed and tested are studied in this paper.The type of hydrochemical compo-nent,characteristics of ion contents relativity,distribution characteristics and influence factor are described. Results indicate that the hydrochemical type of karst groundwater is Ca-HCO3 or Ca·Mg-HCO3;the back-ground values of the items are lower than the values of grade Ⅲ of the National Water Standard.The results show that only several indicators (such as Zn,Se and Hg ) in karst groundwater of the study area have changed significantly and are unevenly distributed. Other indicators have changed insignificantly and are evenly distributed in groundwater.All the elements have no correlation with pH,while there is clear positive correlation among HCO3-,Ca2+,Mg2+,K+,Na+,SO2-4 ,NO3-,I -,total hardness.HCO3-,Ca2+and Mg2+play a decisive part on the elemental relationship.The spatial distribution of elements assumes sheet dis-tribution characteristics,which is controlled by the geologic background,geographic condition and human activities.
