摘　　要：随着城市发展,济南城市供水与保泉问题的矛盾日益突出,必须在保证不影响泉水的前提下合理开发地下水资源。选取济南地区1990~2005年的月降雨量、趵突泉泉群水位数据,利用降雨量移动平均值法分析降雨补给特征及泉域水位对降雨量的响应滞后性特征,在降雨量三点移动平均值时开始与泉域水位具有相关性,降雨量十点移动平均值与泉域水位的相关性最强,泉域水位与前十个月的综合降雨量关系密切。降雨量经十点移动平均处理后,降雨量和泉域水位同时上下波动,通过对比分析城区、济东、济西地下水开采量数据,证明泉域水位与城区、济西地下水文单元水力联系密切,与济东地下水文单元不存在水力联系,可合理开采济东地下水单元。With the development of the city, the contradiction between urban water supply and spring protection has become increasingly prominent, and the groundwater resources must be developed reasonably under the premise of ensuring that the spring water is not affected. Monthly rainfall and water level data of Botu Spring Group from 1990 to 2005 in Jinan area were selected to analyze the characteristics of rainfall recharge and the lagging response of water level in spring area to precipitation by statistical method. When the average of three-point movement of precipitation starts to correlate with water level in spring area, the average of ten-point movement of precipitation has the strongest correlation with water level in spring area. The current spring water level is closely related to the comprehensive rainfall in the first ten months. After ten-point moving average treatment of precipitation, through comparative analysis of groundwater exploitation data in urban area, east of Jinan and west of Jinan, it is proved that water level in spring area is closely related to groundwater hydrology unit in urban area and west of Jinan, and there is no hydraulic connection with groundwater hydrology unit in east of Jinan, so groundwater unit in east of Jinan can be reasonably exploited.
