摘要: 为了解泰莱盆地孔隙水水化学特征及控制因素，运用数理统计、相关性分析、Piper图、Gibbs图等方法，分析了研究区孔隙水的主要离子及水化学特征，并探讨了其控制因素.结果表明，泰莱盆地孔隙水中主要阳离子为Ca²⁺、Na⁺，占阳离子总量的86%以上，而阴离子则以HCO₃^-、NO₃^-、SO₄^2-为主，占阴离子总量的85%以上；水化学类型较为复杂，以HCO₃·SO₄（SO₄·HCO₃）-Ca·Mg（Ca）为主；pH均值为7.42，其pH变异系数较小，整体呈现弱碱性；研究区TDS均值为866.09 mg·L^-1，其北部及南部靠近基岩区的TDS值整体较小，呈现出南、北两侧值低，越向泰莱盆地中部越高的现状.Gibbs图及离子端元图结果表明，水化学组分主要受水-岩作用控制，以硅酸盐岩风化溶解为主且存在碳酸盐岩风化溶解，分析与研究区南、北部基岩裂隙水和岩溶水的补给有关.

Abstract: In order to survey chemical characteristics and control factors of pore water in Tailai basin, 40 pore water were sampled in 2017.By means of mathematical statistics, correlation analysis, Piper diagram and Gibbs diagram, main ion and hydrochemical characteristics of porewater were analyzed, and its control factors were discussed. The results showed that Ca²⁺ and Na⁺ were the main positive ions in porewater of Tailai basin, accounting for more than 86% of the total positive ions, HCO₃^-,NO₃^- and SO₄^2- were the main anions, accounting for more than 85% of the total anions. The types of hydrochemistry were complex and mainly type was HCO₃·SO₄ (SO₄·HCO₃)-Ca·Mg (Ca).Mean of pH was 7.42, and variation coefficient was small, belong weak alkalinity. Mean of TDS was 866.09 mg·L^-1, in the north and south of the study area near the bedrock area showed low values, and higher in the middle of the Tailai Basin. The hydrochemical components were mainly controlled by water-rock action, mainly by weathering dissolution of silicate rocks and carbonate rocks.
