摘　　要：在系统分析安阳市“7·19”特大暴雨洪水事件的基础之上,探讨典型极端降雨条件下安阳市东部平原区地下水对暴雨洪水事件的响应。在利用灰色关联分析法确定安阳市东部平原区浅层地下水水位和降雨量二者之间的相关程度的基础上,提出一种基于ArcGIS软件的地下水补给量计算模型。研究结果表明:安阳市平原区浅层地下水水位与降雨量的关联系数大于0.85,地下水资源量变化受降雨补给影响显著;“7·19”事件降雨强度大,雨量集中,受大范围强降雨影响,地下水位变幅沿河道向两岸方向没有形成递减的变化趋势,水位变幅与降雨分布呈正比;此次洪水为单峰型洪水,模型计算研究区地下水补给量为5.19亿m^(3),洪水转化率0.8%。该计算模型适用于资料缺乏地区地下水补给量计算和雨洪资源化定量分析,对雨洪资源利用和地下水响应分析具有一定的参考价值。The North China Plain has become the most serious groundwater overexploitation area in China due to development and utilization of groundwater resources.Rainwater resources have gradually attracted people′s attention because of potential water resources.However,most of the current researches focuses on increasing the conversion rate of rain-flood resources and analyzing the fluctuation of groundwater level,lacking the concerns on the characteristics and amount of groundwater recharge under the influence of rain-storm flood events.Based on the systematic analysis of rain and flood events,the response characteristics of groundwater to rain-storm flood events is discussed,a groundwater recharge solution model based on ArcGIS software is proposed to quantitatively analyze the response of groundwater to the events.7/19 heavy rain-storm flood event in Anyang City is taken as an example.Based on the long-term monitoring data of groundwater level and rainfall,the grey correlation coefficient between the elevation value of groundwater level and the precipitation in the corresponding period is calculated,and the correlation between the variation range of groundwater level and the precipitation is determined.The collected monitoring data of the 7/19 heavy rain from groundwater level monitoring wells and precipitation monitoring stations in the plain area of Anyang City are used to analyze the spatial distribution characteristics of rainfall.Groundwater recharge solution model is established through ArcGIS according to the temporal and spatial distribution characteristics of rainfall and the changing trend of groundwater level.The steps are as follows:the variation of groundwater level is calculated and the point data is filled into the whole study area by Kriging interpolation;use the surface analysis tools of ArcGIS to partition data such as water level variation and hydrogeological parameters to establish corresponding attribute thematic layers;perform overlay analysis on attribute thematic layers,define projection to c
