| 摘 要： | 国外学者已广泛应用Sr^2 ，c(Sr)／c(Ca)或c(Ca)／c(Sr)，n(^87Sr)／n^(86Sr)作为示踪元素研究地表河水的来源组成、监测地下水的污染程度、确定含水层的越流补给量和恢复洞穴沉积环境等。国内90年代以后开始应用锶和锶同位素研究河流的补给来源，探讨泉群流动系统和应用c(Sr)／c(Ca)、c(Sr)／c(Mg)研究岩溶水系统，并取得了较好的效果；介绍了目前正在开展的应用c(Sr)／c(Ca)、c(Sr)／c(Mg)、n(^87Sr)／n(^86Sr)研究西南岩溶山区地下河水组成的思路和方法。展望了锶元素地球化学在水文地质调查和地下水资源评价中的应用前景。

| Abstract: | Strontium is the richest trace element in the upper lithosphere.It is inactive to most substances in natural conditions due to its stable chemical characteristics.Moreover,its contents have obvious differences in various geo-hydrogeological settings.Therefore,strontium is widely used as a microelement tracer abroad.Sr~(2+),c(Sr)/c(Ca) or c(Ca)/c(Sr),n(~(87)Sr)/n(~(86)Sr) are used by foreign scholars in investigation of the contribution of different river sources,groundwater pollution monitoring,estimation of leakage recharge quantity and reconstruction of cave sedimentation environment.Strontium and its isotopes are also employed as tracers in river resources,spring flow system and karst water system research,c(Sr)/(c(Ca),)(c(Sr))/c(Mg) used in China since 1990's.In this paper,we have discussed current work about the application of c(Sr)/c(Ca),c(Sr)/c(Mg),n(~(87)Sr)/n(~(86)Sr) in subterranean stream composition research on karst area in western-southern China,and finally,prospected the future development of element strontium in hydrogeology and underwater resources evaluation. |
