针对2010年以来实施的黄河三角洲刁口河流路恢复过水及湿地生态补水措施，建立黄河三角洲刁口河流路及尾闾湿地地下水数值模型，模拟黄河三角洲刁口河流路及湿地补水前后地下水变化情况，评估刁口河恢复过流及尾闾湿地补水对区域地下水的影响。结果表明，刁口河恢复过水及尾闾湿地补水对地下水具有积极补给作用，在2010年、2011年、2013年生态补水期间，刁口河沿岸地下水渗漏量分别为10.2万 m3／d、10.6万m3／d、9.2万m3／d，刁口河尾闾湿地周边地下水渗漏量分别为1.4万m3／d、2.7万m3／d、1.03万m3／d；随着地下水资源的补给，补水区及周边地下水水位抬升明显，刁口河沿岸及尾闾湿地周边地下水抬升范围分别为950～1100 m和800～1100 m，地下水位最大抬升幅度分别为60～80 cm和35～46 cm。

Abts ract:Based on the flow recovery of Diaokou River in Yellow River Delta and the ecological water supplement of wetland carried out since 2010 , groundwater numerical models of Diaokou River and the tail wetland in Yellow River Delta are established, the phreatic fluctuation before and after water diversion period are simulated, and impacts of the flow recovery of Diaokou River and the ecological water supplement of wetland are evaluated.The result shows that the flow recovery of Diaokou River and ecological water supplement of tail wetland furnished the groundwater nearby.The infiltration of groundwater along the bank of Diaokou River was 10.2×104、10.6×104、9.2× 104 m3/d and the infiltration of groundwater around the wetland was 1.4 ×104、2.7 ×104、1.03 ×104m 3/d in 2010, 2011 and 2013, respectively.With the supplement of groundwater, the groundwater level raise occurred obviously in the supplied area and the areas around, the capture zone scope of groundwater ranged from 950 to 1100m and 800 to 1100m and the max uplift ranged from 60 to 80cm and 35 to 46cm along Diaokou River bank and in the adjacent tail wetland, respectively.
