摘　　要：自 2 0世纪 70年代以来 ,我国在地下水流数值模拟方面取得了大量的成果 ,但与国外的工作相比 ,我们对模型目标的确定、灵敏度分析、模型的后续检查以及模型的再设计等工作重视不够。该文对这些工作程序的目的、功能进行了论述 ,得出结论认为这些工作程序对于地下水流数学模型的校正和提炼有重要作用 ,地下水流数值模型不应是为回答一些急需决策的问题而建立的危机模式模型 ,而应以日常地下水系统的管理为目的 ,建立起管理模式的模型。Great progress has been made in numerical modeling of groundwater in China since 1970's. Compared with the work done in some foreign countries, the numerical modeling of groundwater in China overlooked work steps of model purpose definition, sensitivity analysis, model postaudit and redesign. The function and purpose of these steps were stated and analyzed in the paper. On the basis of this, the author concluded that the above-mentioned steps play an important role in model validation and refinement. Groundwater model shouldn't be only constructed for answering pressing questions,it should be also developed for the purpose of groundwater system management and improved successively as new information source.
