【摘要】 在系统综述区域地下水数值模拟的基础上,运用有限差分和有限体积法,结合济南泉域裂隙岩溶地下水含水介质系统,采用二维非稳定流数学模型进行了数值模拟,对泉域地下水动态变化进行了评价,为泉域地下水资源评价与管理提供了一种有效的分析手段,为区域地下水资源的科学管理提供了有意义的参考。更多还原

【Abstract】 On the basis of summarizing the numerical simulation of groundwater systematically and combining Jinan fissure-karst water system,a two-dimensional unsteady flow model is established by using the finite difference method and the finite volume method.And then the dynamic changes of groundwater in the spring field is asseseed.Some conclusions are drawn so as to provide efficient analysis method for the evaluation and management of groundwater resources of the Jinan spring field;and provide significant reference for the evaluation of scientific management of local groundwater resources.更多还原
