摘要
在分析大区域地下水流数值模型构建缘起的前提下,系统论述了近年来地下水流数值模拟在大区域地下水资源评价、水文地质参数确定、地面沉降、溶质运移、海水入侵、盐渍化、风险评估、地下水管理及地表水与地下水的联合开发利用等方面的国内外研究应用现状;归纳、总结了目前大区域地下水流数值模型在灵敏度分析、裂隙和岩溶介质中模型建立、基于地下水流数值模拟的溶质运移模型建立、地下水流数值模型构建所需工作量等理论和方法研究及实际建模过程中存在的一些问题;展望了今后大区域地下水流数值拟在研究范围、模拟技术与方法以及与其它模型耦合等方面的发展趋势。
On the basis of analysing the reason of numerical model construction of groundwater flow in a large-scale area, the paper emphasized on discussion of the current situation at home and abroad as follows： groundwater resources evaluation, determination of hydrogeological parameters, land subsidence, solute transport, seawater intrusion, salinization, risk assessment, groundwater management, the united exploitation and utilization stage of the underground and surface water, and so on. Based on this result, some problems that exist in the process of sensitivity analysis, model foundation in karst fractured rock mass, model foundation of solute transport based on numerical model of groundwater flow, workload of modeling of numerical model of groundwater flow are analyzed and summarized; Development trend of numerical model of groundwater flow in a large-scale area is prospected in the following aspects such as research scope, simulation technology and method, and coupling with other model.
