摘　　要：通过测试晋江市地下水矿化度、pH值及大组分阴、阳离子含量,利用地统计中克吕格法对矿化度插值得出其空间分布特征,并通过Durov水化学图分析晋江市地下水的水化学特征及与矿化度和pH值之间的关系.按照CA卡列夫地下水化学类型划分标准确定该地区地下水类型主要以Cl-·HCO-3—K++Na+·Ca2+型为主.对矿化度与大组分阴、阳离子做相关及偏相关,分析与阴离子(Cl-、HCO-3、SO2-4)在α=0.05下存在相关,与HCO-3离子呈现出极显著相关.影响分析结果表明,晋江时候地下水过度开采导致海水入侵、岩体溶滤是造成晋江市部分地区矿化度升高的主要原因之一.Through test and analysis concentration about total dissoloved solid, pH, anions and cations of groundwater in Jinjiang, the use of krining value method in geo-statistics analysis spatial distribution of total dissoloved solid of spatial distribution, the over-exploitation of groundwater and seawater intrusion are one of the most main reason total dissoloved solid concentration increase in some areas of Jinjiang. Through Durov diagram analysis water chemistry and total dissoloved solid or pH as well as the distribution of values of groundwater in Jinjiang. Follow the chemistry types of groundwater to determine this ares main types is Cl^- · HCO3^--K^＋ ＋Na^＋· Ca^2＋.The total dissoloved solid and anionic, cationic correlation and partial correlation, analysis there is correlation anion （included Cl^- , HCO3^- , SO4^2- ） being in α = 0.05, especially showing a highly significant correlation with HCO3^- ion.The analysis results show that effect leads to seawater intrusion,rock dissolution is one of the main causes of mineralization in some areas of Jinjiang City,increase its excessive exploitation of groundwater.
