摘　　要： 山西省延河泉岩溶水系统是我国北方岩溶大泉之一。依据碱土金属比值Sr Mg、Sr Ca与矿化度关系,分析了延河泉岩溶水系统Sr Mg、Sr Ca分布规律及形成条件。从补给区到径流区、排泄区,Sr Mg、Sr Ca值逐渐增高;径流条件好,Sr Mg、Sr Ca值低;径流条件差,其值高;径流滞缓区最高。并且Sr Mg、Sr Ca值主要受径流条件控制,不受人为作用的影响。因此,Sr Mg、Sr Ca是比较理想的天然示踪剂。根据Sr Mg、Sr Ca值将延河泉岩溶水系统划分为三个子系统,即下河泉子系统(泉1、2、3、5),延河泉子系统(泉4、6),南部散泉子系统(泉7、8、9)。 Yanhe spring karst water system is one of the famous springs in North China. Based on the graphs of TDS and ratios of Sr/Mg、Sr/Ca,this paper discusses the distribution principles and reasons of Sr/Mg、Sr/Ca of Yanhe spring karst water system. The results indicated that the ratios increase from recharge area to discharge area; the better runoff conditions, the higher ratios, and they arrive at the top in stagnant zone. In karst water system Sr/Mg、Sr/Ca ratios are mostly affected by runoff conditions, not by human activities, they are ideally natural tracers. According to Sr/Mg、Sr/Ca ratio,Yanhe spring karst system is divided into three subsystems taking the hydrogeological conditions into account, that is Xiahe spring subsystem (spring1,2,3,5), Yanhe spring subsystem(spring 4,6) and subsystem of scattering springs in southern catchment(spring 7,8,9).
