摘　　要：文中在新疆祁漫塔格地区152组地表水水化学测试数据的基础上,通过描述性统计分析结果可知研究区地表水属于矿化度、总硬度总体偏高的弱碱性水,地表水中阳离子以Na^++K^+为主,阴离子以Cl^-和SO_4^(2-)为主;采用阿廖金分类法划分地表水水化学类型,研究区地表水以ClNaⅢ、ClNaⅡ型水为主。通过相关性分析、Gibbs图解法、阴阳离子三角图法、离子比值端元图法和饱和指数法等对地表水水化学成因进行分析,分析结果表明研究区地表水化学组分主要受硅酸盐岩和蒸发盐岩(岩盐和硫酸盐矿物)的风化溶解和蒸发-浓缩作用的影响,而大气降水作用和人类活动对地表水化学组分的影响不大。The results of testing of 152 surface water sampling points in Qimantage area of Xinjiang showed that the surface water is weak alkaline and belongs to the high total hardness and mineralization by the descriptive statistics analysis. The surface water is dominated by Na ＋ ＋ K ＋ in cations and SO4 2- , Cl- in anions. The hydrochemical types can be classified into Cl Ⅲ Na type and Cl ⅡNa type by Arliekin＇s classification. We also analyzed the causes of surface water hydrochemistry with the methods of correlation analysis, Gibbs diagram, triangle plots for the cations and anions, end - member diagram of ionic ratios and saturation index. The results showed that surface water chemical compositions are mainly influenced by the weathering of silicate rocks and evaporate rocks （ including rock salt and sulphate mineral）, and strong evaporation. However, the atmospheric precipitation and human activities have little effect on the surface water chemical compositions.
