摘　　要：陕西渭北东部岩溶水系统是一个复杂的地下水系统,碳酸盐岩大面积隐伏与深埋。使用传统手段和方法勘查岩溶地下水和研究可持续开发利用方案遇到诸多困难,不仅费时,而且耗资大。本文通过系统分析研究陕西渭北东部地区岩溶地下水T、D、180、14C环境同位素特征,揭示岩溶水的补给迳流排泄条件、岩溶水系统边界性质以及岩溶水与黄河洛河地表水、黄河岩溶泉与洛河岩溶泉之间的补排关系。结果显示环境同位素方法简便有效,能够达到预期目的。The karst groundwater system in the eastern part of Weibei, Shaanxi Province is a relatively complicated one. Environmental isotopes such as T, D, ^(18)O, ^(14)C of the karst groundwater were systematically examined in this article. The results of the environmental isotopic analyses further reveal: (1) the hydrogeologic conditions of karst groundwater including the recharge, runoff, discharge and boundaries of the system, (2) the relationship between the karst water and the surface water bodies of the Luohe River and the Yellow River, and (3) the relation between the karstic springs in the Luohe River and the Yellow River.
