新郑市浅层地下水流数值模拟及评价

通过分析新郑市水文地质条件,建立了概念模型,运用GMS软件建立三维地下水流的数值模拟模型,对研究区浅层地下水资源进行现状评价,并对2015年和2020年地下水位进行了预测.结果表明,研究区地下水水位持续下降,到2020年水位将会下降5～10 m,部分地区可能会出现开采漏斗,为了降低地下水位的下降幅度,应该调整产业结构,加强水资源的管理,提高水资源的利用率,从而减少地下水资源的开采.

Numerical Simulation and Evaluation of the Shallow Groundwater in Xinzheng City

By analyzing hydrogeological condition of the Xinzheng city, this paper presents a conceptual model, and a three-dimensional numerical simulation model of the groundwater was built with the GMS software. Current groundwater resources of shallow aquifers are evaluated with the model. The groundwater levels were predicted for years 2015 and 2020. The result shows that the groundwater levels will continue to decline in the study area. The water level will drop by 5-10 m in 2020, depression cones may be formed in some areas. In order to slow down groundwater level drawdown, we should adjust the industrial structure, strengthen the management of water resources, and improve water use efficiencY in order to reduce groundwater development.
