郑州市长期过量开采地下水致使地下水位大幅度下降，由此引发了一系列水环境问题：１）区域地下水降落漏斗形成并不断扩展；２）大幅度增加供水难度和费用；３）导致水环境质量恶化；４）诱发地面塌陷和沉降．研究区内地下水系统（＜２５０米）可概化为浅层地下水系统和中深层地下水系统，两者通过弱透水层系统发生水力联系．本项研究根据抽象出的研究区地下水系统概念模型，建立了地下水流场准三维模拟模型．经模型校正和识别后对研究区地下水流场做了数值预报，并基于此提出流场宏观调控技术方案
A long period of excessive exploitation of groundwater in Zhengzhou led to a drastic drop in groundwater table, which triggered a series of water environmental problems: 1) the formation and continuous expansion of regional groundwater descent funnel; 2) a substantial increase in the difficulty and cost of water supply; and 3) Deterioration; 4) Induced ground subsidence and settlement. The groundwater system (<250 m) in the study area can be generalized to shallow groundwater systems and mid-deep groundwater systems, both of which have hydraulic connections through the aquitard system. Based on the abstract conceptual model of groundwater system in the study area, this study established a quasi-three-dimensional simulation model of groundwater flow field. After the model is calibrated and identified, the groundwater flow field in the study area is numerically predicted, and based on this, the macro-control scheme for the flow field is proposed
