研究处于天然状态地区的地下水水化学特征对地下水污染调查分析具有重要意义。利用新疆汉水泉地区39组地下水水样，依据研究区水文地质条件，运用舒卡列夫分类法和 SPSS、MAPGIS 与 Surfer 等软件进行综合分析，揭示地下水水化学组分在水平和垂直方向的演化规律。结果表明：研究区共存在4种水化学类型，分别为SO4-Na·Ca、SO4·Cl-Na·Ca、Cl·SO4-Na·Ca 和 Cl-Na；潜水 TDS 与 K++Na+、Ca2+和 Cl-呈显著相关性，承压水 TDS 与 K++Na+和 Cl-呈显著相关性，主要离子浓度的空间分布特征与 TDS 近于一致；汉水泉地区地下水化学类型、TDS 与主要离子浓度存在明显的分带规律，水化学特征的形成主要受溶滤作用、阳离子交换吸附作用、浓缩作用与混合作用影响。

Study on the groundwater chemical characteristics in natural state is of great importance for the investigation and anal-ysis of groundwater contamination.In this paper,the statistical analysis method of Shukarlev classification,and software of SPSS,MAPGIS,and Surfer were used to analyze the evolution characteristics of chemical components in the horizontal and ver-tical directions based on the 39 groundwater samples collected from the Hanshuiquan region in Xijiang and the hydrogeological conditions in the area.The results showed that (1)there are four hydrochemical types including SO4-Na·Ca,SO4 ·Cl-Na·Ca, Cl·SO4-Na·Ca,and Cl-Na;(2)TDS has significant correlation with K+ + Na+ ,Ca2+ ,and Cl- in unconfined groundwater while TDS has significant correlation with K++ Na+ and Cl- in confined groundwater;(3)spatial distribution of the main ion concentrations is consistent with that of TDS;(4)The TDS,main ion concentrations,and groundwater hydrochemical types have apparent zonations;and (5)leaching,ion exchange,concentration,and mixing are the major processes to form the ground-water hydrochemical type.
