Analysis on hydrochemical characteristics and formation mechanism of groundwater in Qinzhou Port Area, Guangxi, China
摘要
Abstract
For further revealing the hydrochemical characteristics of groundwater and the hydrochemical pro-cesses, 68 sets of shallow groundwater were collected during dry season and rain season in Qinzhou Port to mea-sure Na+、Ca2+、Mg2+、HCO3-、Cl-、SO42- and TDS, and studied hydrochemical characteristics and formation mecha-nism. The results show that seasonal variation has less influence on the spatial variation. The main hydrochemical types of groundwater is Ca-Mg-SO4-Cl, and evolve from Ca-Mg- HCO3 type and Na-Cl-SO4 type to Ca-Mg-SO4-Cl type. The groundwater hydrochemical composition is formed by weathered-leached effects, ion-exchange adsorption and evaporation concentration. The impact of human activity on groundwater is increas-ing important, and the groundwater hydrochemical composition is keeping development and change.关键词
