以郑州市为例，针对城市区域长期过量开采地下水导致的一系列严重的环境地质灾害，诸如地下水水位持续下降形成区域地下水降落漏斗并不断扩张、含水层疏干、供水井吊泵、泉水断流、地下建筑工程浸没、地面沉降和塌陷等，探讨了城市地下水流场人工调控的减灾方案。建立了地下水系统的准三维动态数值仿真模型，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了三维数值仿真模型。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。在此基础上，通过地下水渗流场的宏观调控与优化管理，使研究区内不合理开采地下水资源所引发的环境灾害减小到最低程度，为郑州市的环境减灾工作提供了科学依据。
Taking Zhengzhou City as an example, a series of serious environmental and geological disasters caused by long-term overexploitation of groundwater in urban areas such as continuous decline of groundwater level and continuous expansion of groundwater descent funnel, dredging of aquifers, suspension of water supply wells, , Submerged underground construction, land subsidence and collapse, etc., to explore the artificial groundwater flow control measures for disaster reduction. The quasi-three-dimensional dynamic numerical simulation model of groundwater system is established. The groundwater flow is simulated by the heterogeneous isotropic seepage model and the three-dimensional numerical simulation model is solved by the irregular triangular mesh finite difference method. First, solve the inverse problem inverse parameter, and then solve the problem of calculating the amount of groundwater resources, numerical simulation forecast groundwater seepage field to 1998. On this basis, through the macroscopic regulation and optimization management of groundwater seepage field, environmental disasters caused by irrational exploitation of groundwater resources in the study area are reduced to a minimum, which provides a scientific basis for environmental mitigation in Zhengzhou City.
