摘　　要：傍河水源地是郑州市重要的地下水供水水源。在出现极端干旱或极端事故(如水质污染)的条件下,傍河水源地将启动应急开采满足城市供水的需要。通过建立郑州市350m深度内松散岩类孔隙水地下水数值模拟模型,对黄河水位下降情况下的地下水应急开采方案进行了预测,分析了应急开采对黄河侧向补给的影响及傍河水源地地下水位的演变趋势。结果表明,应急开采方案下激发了黄河的侧向补给,一年的预测期末傍河水源地没有出现地下水位持续下降、降落漏斗进一步扩大的问题。Riverside wellfields are very important sources of water supply in Zhengzhou.Under the condition of extreme drought or extreme accident(for example,water pollution),riverside wellfields will start an emergency exploitation to meet the needs of urban water supply.This study focuses on the aquifer within 350meters deep in the Zhengzhou area and a 3-D groundwater flow model is constructed.With this model,the exploitation scheme of groundwater emergency in case of a drawdown of water level of the Yellow River is forecast and the impact of seepage of the Yellow River and the trend of water level of the wellfields are also evaluated.The results show that the emergency exploitation increases the amount of seepage of the Yellow River,and it will have little impact on groundwater level of the riverside wellfields.
