【摘要】 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。更多还原

【Abstract】 Due to serious over exploitation of groundwater in North Weifang at present,on the basis of analyzing hydrogeological conditions,Visual MODFLOW software was used to establish a numerical simulation model of groundwater.The rationality of the model was analyzed by water level fitting and water balance.And then groundwater flow field in different mining conditions for the next five years(2016-2020)were predicted.Finally,the change trend was revealed under the condition of nature and human impact.The results show that under the conditions of underground water pressure and recharge source,the water level of the study area is higher than the initial flow field,and the maximum recovery of water level is 11 m,and the underground water level recovers obviously.Therefore,it can be the best recovery plan of water level.This research results can provide scientific basis for the treatment of groundwater overdraft and the restoration of water level.更多还原
