摘　　要：以1∶5万水文地质调查兴山县幅内的白龙泉为例,介绍了如何在水文地质调查工作基础上,综合利用地球物理勘探、示踪试验、同位素测试等手段,查明岩溶泉的成因,并对其水文地质特点进行分析。在此基础上,对多手段查明岩溶泉成因的应用进行了探究。裂隙测量等基础地质调查测得了研究区代表性含水岩组的裂隙发育程度,为岩溶发育规律的研究提供了重要的参考;地球物理勘探确认了白龙泉的补给径流区中存在岩溶径流管道;示踪试验数据可分析岩溶径流管道的管道结构;而同位素测试则从水化学角度佐证了上述方法所得的结论。技术方法可以为南方岩溶大泉或地下河的水文地质调查提供一些有价值的经验。In this paper, the Bailong spring in Xingshan County is taken as an example for introducing how to make a comprehensive utilization of the geophysical exploration, tracer test, isotope test and other methods to find out the causes of karst springs and analyzing the hydrogeological characteristics based on the 1：50 000 hydrogeological survey. Multiple means to find out the causes of karst springs are also studied. Fracture measurements and other basic geological surveys reveal the crack growth degree of the representative aquifers in the study area, and provide important reference for subsequent studies on the regularity of karst development. The geophysical exploration confirms the existence of the Bailong spring＇ s karst pipeline. The data of the tracer test can be used to discuss the characteristics of the karst pipeline. In addition, the isotope test corroborates the aforesaid conclusion from the viewpoint of the hydrochemistry. The techniques and methods summarized in this paper could provide some valuable experience for the investigation of large karst springs in southern china.
