黄河下游影响带含水系统激发补给动态调蓄研究

黄河下游悬河的特殊地质环境条件,使黄河水与其影响带地下水水力联系密切,地下水开采潜力大。为优化水资源联合调度,刻画地下水集中供水水源地与含水系统调蓄的内在联系,根据地下含水系统岩性结构及地下水的补、径、排条件,按水源地定流量的开采方案,建立浅层地下水二维水流模型。应用FEFLOW软件,对黄河下游影响带10处地下水水源地进行激发补给动态调蓄模拟预测。结果显示,傍河水源地开采条件下,可以通过增大黄河的侧渗补给量,实现含水系统动态调蓄水资源的功能。

Groundwater Recharge Capacity Regulation under Intensive Exploitation among the Affected Zone of the Yellow River Downstream

Under the special geological environment of hanging river in the lower reaches of the Yellow River,the water of the Yellow River is closely related to the power of groundwater in the area that is affected by the Yellow River,the exploitation potential of the groundwater is great.For optimizing united management of water resources,depicting the inner link between the centralizing water supplying waterhead area of groundwater and the regulating sluice of water system,according to the lithology structure of groundwater system and the supplementary,runoff and drainage condition of groundwater,the planar current model of the shallow stratum groundwater had been constructed in this paper as the fixed flux exploitation plan of the groundwater resources.The analog forecast of exploded supplementary capacity regulation had been done in 10 groundwater resources of the affected zone of the Yellow River downstream with FEFLOW software.The results showed that the function of the hydrous system capacity regulation of water resources could be actualized by augmenting the side filter replenishment of the Yellow River in the exploiting water source area along riparian of river.
