地下水多层含水层系统的动态数值仿真

Dynamical Simulation for Multi Aquifer Systems

建立地下水多层含水层系统的动态数值仿真模型，对郑州市地下水流场进行预报和评价。以非均质各向同性渗流模型仿真地下水流，用不规则三角网格有限差分法求解三维数值仿真模型。先解逆问题反求参数，再解正问题计算地下水各项资源量，数值仿真预报地下水渗流场至１９９８年。通过地下水渗流场的优化调控，使研究区内不合理开采地下水资源所引发的环境问题减小到最低程度。

The models for the quasi three dimensional dynamical simulation are built for controling and optimizing the groundwater seepage field in Zhenzhou City. The groundwater flow is simulated with the seepage model of heterogeneity isotrope, and the partial differential equations are solved with finite difference scheme of irregular triangle net. Firstly, the inverse problem is solved for parameters calculating, then the positive problem is solved to calculate groundwater resources, and the groundwater field in the future is predicted under the condition of planned pumping from 1996 to 1998. The optimal control and management of the groundwater seepage field make the harmful environment problem reduce to its minimum in overall research area.
