摘　　要：了解巩义市城区地下水水位动态,为巩义市城区地下水资源利用提供依据,实现地下水资源的高效利用,为此,在巩义市城区布设了地下水位监测点.依据近3年的地下水位监测点的监测数据,分析巩义市城区的年内、年际间降水量对地下水位监测点的水位动态、水位埋深以及地下水降落漏斗变化趋势的影响.结果表明:研究区地下水位埋深较浅,降水量是其地下水位动态变化的主要影响因素;其中年内地下水位变化以相对稳定的季节性变化为主,而年际间地下水位处于动态平衡状态;研究区深层承压水含水层是主要的供水来源,长期过量开采,形成了较大的地下水降落漏斗,在实行限采的情况下,地下水降落漏斗保持稳定,基本实现采补平衡.To understand the dynamic of groundwater table in Gongyi City,provide some basis for the groundwater resources in Gongyi City,and achieve the high-efficient use of groundwater resources,the monitoring points of groundwater table were laid in the urban area of Gongyi City. Based on the monitoring datum of monitoring points of groundwater table in nearly 3 years,we analyzed the influence of the annual and inter-annual precipitation on the dynamic of groundwater table,the depth to groundwater table and the change trend of groundwater drawdown funnel. The results show： in the research area,the depth to groundwater table is shallower,the precipitation is the main influence factor of the dynamic fluctuation of groundwater table; the annual fluctuation of groundwater table is mainly the seasonal fluctuation,the inter-annual groundwater table is in a state of dynamic balance; the aquifer of confined water is the main supply source of the research area,but the long-term excessive mining results in larger groundwater drawdown funnels; under the condition of limit mining,the groundwater drawdown funnel will keep stable,and the groundwater will basically realize the balance between mining and recharging.
