摘　　要：针对地下水数值模拟中参数的不确定性直接影响模拟结果的准确性问题,在分析概化吉林省西部水文地质条件基础上,建立了水文地质概念模型和地下水数学模型,采用HydroGeoSphere软件求解模型,并选取含水层的渗透系数、给水度及贮水系数进行灵敏度分析。结果表明,含水层的给水度和贮水系数对模拟结果的影响较大,且获得了敏感性最大的参数分区,为该区地下水资源的合理开发利用和管理提供了科学依据。Uncertainty of parameter directly affects the accuracy of numerical simulation of groundwater. Based on analyzing and conceptualizing hydrogeologic conditions of the western of Jilin province, hydrogeologieal conceptual model and mathematical model of groundwater are established, which are solved by HydroGeoSphere software. And then the hydraulic conductivity, the specific yield and storage coefficient of aquifer are selected for sensitivity analysis. The results indicate that the simulation results are relatively sensitive to the specific yield and storage coefficient; the parameters parition ranges with maximal sensitivity are obtained. Thus, it provides the scientific basis for rational exploitation and management of groundwater resources in this area.
