摘　　要：淄博市人均水资源量300m3,水资源供需长期处于“紧平衡”状态。淄博盆地内地下水资源丰富,是淄博市各区的主要供水水源地,研究其岩溶水赋存规律及电性响应特征,对地下水资源的合理开发利用具有重要意义。本文在综合分析研究前人成果资料的基础上,选择盆地内典型水源地进行补充水文地质调查及物探测量工作。研究成果表明:碳酸盐岩类裂隙岩溶水含水岩组是研究区最主要的含水岩组,可划分为上寒武统及中—下奥陶统裂隙岩溶水含水岩组和中—下寒武统岩溶裂隙水含水岩组两大类;岩溶水赋存类型主要为层状岩溶裂隙带型,电性特征表现为层状中低阻异常特征,对应的视极化率、视激发比和视衰减度曲线整体呈峰值反映。The per capita water resources in Zibo City are 300 cubic meters,and the supply and demand of water resources are in a state of"tight balance"for a long time.Zibo Basin is rich in groundwater resources,which is the main water supply source of various districts in Zibo City.It is of great significance to study the occurrence rule of karst water and the characteristics of electrical response for the rational development and utilization of groundwater resources.On the basis of comprehensive analysis and research of previous results,this paper selects the typical water sources in the basin for supplementary hydrogeological survey and geophysical survey.The research results show that the carbonate fissure karst water-bearing rock group is the most important water-bearing rock group in the study area,which can be divided into two categories:Upper Cambrian,Middle and Lower Ordovician fissure karst water-bearing rock group and middle and lower Cambrian karst fissure water-bearing rock group.The occurrence type of karst water is mainly stratified karst fracture zone,and the electrical characteristics are stratified medium-low resistivity anomalies.The corresponding curves of apparent polarizability,apparent excitation ratio and apparent decay are reflected by peaks.
