摘要
为查明钦州港地区地下水水化学特征及形成作用,本文分枯水期、丰水期采集了钦州港地区68组浅层地下水样,测试Na+、Ca^(2+)、Mg^(2+)、HCO3-、Cl-、SO42-和总溶解固体(TDS)等化学指标并进行了相关分析。结果表明:1季节变化对地下水水化学空间变异性影响较小;2地下水水化学类型以Ca-Mg-SO_4-Cl型为主,主要从Ca-Mg-HCO_3型和Na-Cl-SO_4型向Ca-Mg-SO_4-Cl型演化;3地下水水化学成分主要通过溶滤作用、阳离子交换吸附作用、蒸发浓缩等形成,人类活动对地下水的影响越来越重要,导致了地下水化学成分不断发展变化。
For further revealing the hydrochemical characteristics of groundwater and the hydrochemical processes,68 sets of shallow groundwater were collected during dry season and rain season in Qinzhou Port to measureNa＋、Ca2＋、Mg2＋、HCO3-、Cl-、SO42- and TDS, and studied hydrochemical characteristics and formation mechanism.The results show that seasonal variation has less influence on the spatial variation. The main hydrochemicaltypes of groundwater is Ca-Mg-SO4-Cl, and evolve from Ca-Mg- HCO3 type and Na-Cl-SO4 type toCa-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 increasingimportant, and the groundwater hydrochemical composition is keeping development and change.
