鉴于潍坊北部地下水超采严重的现状,在分析其水文地质条件的基础上,利用Visual MODFLOW软件建立地下水数值模拟模型,通过水位拟合、水均衡等分析模型合理性,并预测不同开采条件下未来五年(2016~2020年)的地下水流场,揭示其在自然、人为影响条件下的变化趋势。结果表明,研究区在地下水压采、回灌补源的条件下,相比初始流场,水位最大回升幅度为11m,地下水位回升明显,可作为水位最佳恢复方案。研究成果可为地下水超采治理和水位恢复提供依据。
In view of the serious status quo of groundwater over-mining in northern Weifang, based on the analysis of its hydrogeological conditions, a numerical simulation model of groundwater is established by using Visual MODFLOW software. The model rationality is analyzed by water level fitting and water balance and the future of different mining conditions is predicted Five years (2016 ~ 2020) of the groundwater flow field, reveals its natural and man-made changes in the trend. The results show that under the conditions of groundwater drainage and recharge, compared with the initial flow field, the maximum recovery range of water level is 11m, and the groundwater level rises obviously, which can be used as the best recovery plan of water level. The research results can provide basis for groundwater over-exploitation and water level recovery.
