水资源的不合理利用、地下水的过渡开采导致了洛阳盆地水环境的恶化。本文结合洛阳盆地水文地质条件运用数学模型对盆地的浅层孔隙地下水资源进行模拟评价。结果表明:建立二层结构的非均质三维非稳定流数学模型,经模型识别和校正,所选参数是基本合理的,可以比较准确地模拟洛阳盆地第四系浅层地下水系统。盆地地下水补给主要为降水及灌溉入渗补给,地下水排泄主要为人工开采,占总排泄量的75.82%,因此调整和优化现状地下水开采方案,合理开采地下水资源显得尤为必要。
The irrational use of water resources and the transitional mining of groundwater have led to the deterioration of the water environment in Luoyang Basin. Based on the hydrogeological conditions in Luoyang Basin, mathematical models are used to evaluate the shallow pore water resources in the basin. The results show that the establishment of a two-layer heterogeneous three-dimensional unsteady flow mathematical model can be used to simulate the shallow groundwater system of Quaternary in Luoyang Basin more accurately by the model recognition and calibration. The recharge of groundwater in the basin is mainly for precipitation and irrigation infiltration. The drainage of groundwater is mainly man-made mining, accounting for 75.82% of the total discharge. Therefore, it is necessary to adjust and optimize the current groundwater exploitation plan and exploit groundwater resources reasonably.
