摘　　要：对太原地区的岩溶地下水进行了大量稳定同位素研究后,得出了西山岩溶水与浅层水混合线的公式为;δD=5.6δ^(18)O-16.1。这条混合线与雨水线的交点给出了未混合前西山岩溶水的δD=-75.6‰,δ^(18)O=-10.7‰。从而计算出浅层水对晋祠岩溶泉的补给量约为36％。根据D、O、S稳定同位素数据及水化学特征,可把太原地区岩溶水划分为两个系统——西山岩溶水系统及东山-北山岩溶水系统,兰泉属于东山系统。硫同位素数据表明,这两个岩溶水系统之间存在着水力联系,即有一部分来自西山的岩溶水补给了兰泉。The stable isotope composition of the groundwater in the research area has been determined.A mixing line for the West Hills karst water system and shallow water has been given.The author concluded that the recharge by shallow water to the Jinci spring is about 36%. Two karst water systems are distinguished--the West Hills system and the East and North Hills system.The Lan Spring belongs to the latter. S-isotope data indicate that there is less supply to The Lan Spring from the West Hills karst water system.
