摘　　要：近年来,由于过量开采地下水,潍坊市北部地区形成了大范围的地下水降落漏斗,而漏斗区产生了连续的储水空间。本研究收集了潍坊市北部水文地质条件资料,分析了研究区地质构造,并划分了水文地质单元。同时,选取研究区有代表性的钻孔,绘制了水文地质剖面图,刻画地下含水层的空间分布状态。然后根据土壤粒级将地下空间划分为透水层、弱透水层和不透水层。其中,透水层再细分为潜水含水层、微承压水含水层和承压水含水层。最后,利用松散岩型地下水调蓄公式计算研究区调蓄库容。本研究还利用GMS空间建模,绘制了地下水库三维实体模型。研究结果表明,潍坊调蓄区段内地下水补给源条件及调蓄条件良好,具有很好的储蓄水能力。研究区的调蓄库容为11.81亿m3,可开采量为9.44亿m3。这些研究结果为潍坊市利用地下空间储存水资源提供了数据支持。In recent years, due to excessive exploitation, a vase expanse of groundwater drawdown funnels formed in northertl Weifang City, which has become a continuous water storage space. In this study, we collected hydrogeologieal data of this region and analyzed the geological structure to parti- tion the hydrogeologieal units. Meanwhile, we chose representative drills and drew profiles to describe the spatial distribution of aquifers. According to soil size fraction, the underground space was divided into permeable layer, weak permeable layer and impermeable layer. Of them, the groundwater system consists of phreatic water （shallow groundwater system） , faint confined groundwater and confined groundwater （deep groundwater system）. Finally, the storage capacity was calculated by the formula of unconsolidated rocks. The 3D model of underground reservoir was plotted by GMS. We conclude that the conditions of water supply and regulating are favorable, which possess commendable water - storing capacity in northern Weifang City. Such water storage capacity is 1.18 billion cubic meters, and the exploitable volume is 0. 944 billion cubic meters in the research area. These results provide data support for the utilization of underground water - storing space in Weifang City.
