摘　　要：由于岩溶含水介质的强烈非均质性和各向异性,如何有效认识岩溶含水层内部的水文地质特征为研究难点之一,岩溶泉衰减曲线分析为认识岩溶含水层的一种有效手段。总结了目前广泛用于泉流量衰减曲线分析的几种常见方法,主要包括指数型衰减、非指数型衰减分析方法以及综合型的衰减曲线分析方法,讨论了管道可能对泉流量衰减曲线的影响,最后提出了今后对岩溶泉流量衰减曲线分析拟解决的一些关键问题。Because of strong heterogeneity and anisotropy of the karst aquifer, it is very hard to understand the internal propemes of the karst aquifer. Analyzing the recession curve of the karst spring is an effective way to solve this problem. This paper re- viewed the methods that were widely used to analyze the recession curve of the karst spring, including exponential recession, non- exponential recession and some combination analysis methods. The influence of the conduit on the recession curve was also dis- cussed. Based on these analysis methods, some key problems need to be solved in the future were proposed.
