摘　　要：通过对天桥泉域岩溶水系统水动态和降雨量资料、万家寨水库水位与岸边岩溶水水位动态关系以及岩溶水化学成分进行研究分析,确定了研究区岩溶地下水的流动方向和强径流带的分布位置;总结出了动荡型、滞后型和消耗型三种类型的岩溶水动态变化特征,得出黄河岸边岩溶钻孔水位与水库水位变化同步等结论。在此基础上,对黄河进行了分段渗漏量计算,渗漏量可达6.926m3/s;绘制出了反映天桥泉域岩溶水化学成分变化的水化学三线图。The direction of the karst groundwater flow and the distribution of strong runoff zone in the study area are determined through the analysis on the hydrodynamics and precipitation data from the karst water system in Tianqiao spring basin, on the water table dynamics and chemical components of the groundwater in Wanjiazhai reservoir and the riverbank. The features of three types of hydrodynamics, i.e. the synchronous, the lagging and the consuming type, are summed up from the study. It is concluded that the water table in the bore on the karstic bank of Yellow River changes simultaneously with that in the reservoir. The leaking- yield along the Yellow River bank is calculated by section, which proved that the leakage may reach 6. 926m^3/s. And then, hydro chemical trigraph, which shows the variation of karst hydrochemical components in Tianqiao spring basin, is made.
