摘　　要：针对地质条件复杂的岩溶地区,可通过分析枯期流量衰减过程推求水文地质参数。基于Boussinesq方程构建了Brutsaert和Lopez方法与Mendoza等方法,分析了枯期流量衰减特征与水文地质参数之间的关系。以贵州岩溶地区后寨河流域为例,根据实测枯期流量过程资料推求渗透系数及含水层厚度。计算结果表明,两种方法推求后寨河流域水文地质参数有效可行,可供借鉴。According to the complicated geological condition in Karst basin,hydrogeological parameters are estimated by analysis of dry season runoff depression process.Based on Boussinesq equation,the methods such as Brutsaert,Lopez and Mendoza are established to analyze the relationship between characteristics of dry season flux depression and hydrogeological parameters.Taking the Houzhai River basin in the Karst region of Guizhou Province for an example,the permeability coefficient and aquifer thickness are determined on the basis of observed flow data during the dry season period.The results demonstrate that it is feasible to estimate the parameters with these two methods,which provides reference for engineering application.
