摘要
在对柳林泉域水文地质详细调查的基础上,系统研究了柳林泉域岩溶水水化学类型及分带规律,并对其形成演化特征进行了分析。结果表明:柳林泉域岩溶地下水是矿化度较低的优质淡水,水中优势阳离子为Ca2+、Mg2+,优势阴离子为HCO3-;水化学类型从补给区到深埋区经历了HCO3-Ca·Mg、HCO3-Ca→SO4·HCO3-Ca、HCO3.SO4-Ca·Mg→Cl.SO4-Na·Ca、Cl·SO4-Na的变化过程,具有典型的干旱、半干旱地区水化学演化特征。
Based on the detailed investigation of hydrogeological condition in Liulin Spring Catchment,hydrochemical types and zoning regularity of Liulin Karstic water were systematically studied,and its formation and evolution rule were analyzed.The results show that a）Liulin Karstic groundwater is high quality fresh water with low salinity,its advantage cationic are Ca2＋,Mg2＋,and advantage anionic is HCO-3;b） the hydrochemical types of the groundwater are successively HCO3-Ca·Mg,HCO3-Ca→SO4·HCO3-Ca,HCO3·SO4-Ca·Mg→Cl·SO4-Na·Ca,Cl·SO4-Na from recharge area to deep buried area,the change process accords with typical hydrochemical evolution characteristics of arid and semi-arid climate region.
