摘　　要：为了深入认识济南岩溶泉水及地热水循环过程,本文以泰山北翼碳酸盐岩含水介质空间分布特征为研究出发点,分析其埋藏条件和连续性特征,并利用数理统计、空间插值、Piper三线图、概念模型等方法,结合水动力场、水化学场、水温度场和水年龄场“四场”分析,揭示区域地下水循环规律。结果表明:地表分水岭与齐广断裂、禹王山断裂、聊考断裂等深大断裂控制了泰山北翼地区岩溶含水介质空间展布,大致呈现由南向北埋藏深度逐渐增大的变化趋势,受马山断裂、东坞断裂、文祖断裂等次级断裂影响岩溶含水介质上下盘有不同错动,但东西展布仍具有较好连续性;区域地下水循环过程极其复杂,泰山岩群、寒武纪及奥陶纪各类含水岩组通过排泄-渗漏、断裂垂向径流、水平地下径流等形式发生水流交汇,并在山前局部地区与第四纪松散孔隙水产生水量交换,最终通过泉或人工开采形式排泄。区域地下水流具有统一的“四场”,并且呈现明显的水平与垂向分带特征,大致沿东阿断裂及其延长线—吴家堡—华山—章丘区—淄博磁村一线划分冷泉与地热水的分界线,以600 m、1000 m划分出浅、中、深循环深度分界线;冷泉以浅循环为主,中、深循环为辅,地下水矿化度、温度、年龄偏低,而地热水以中、深循环为主,浅循环为辅,地下水矿化度、温度、年龄偏大。不同含水介质水流具有一定内在关联,构成一个完整的岩溶水系统。In order to gain a comprehensive understanding of the circulation process of karst spring and geothermal water in Jinan on a larger spatial scale,this research paper analyzes the burial conditions and continuity characteristics of carbonate water-bearing media based on their spatial distribution in the north flank of Mount Tai.Furthermore,the study reveals the pattern of regional groundwater circulation through the utilization of mathematical statistics,spatial interpolation,a Piper three-line diagram,a conceptual model,and the“four fields”analysis of hydrodynamic field,hydrochemical field,water temperature field,and water age field.The results show that the spatial distribution of karst waterbearing media in the north flank of Mount Tai is controlled by surface watersheds and deep faults such as Qiguang fault,Yuwangshan fault,and Liaokao fault.There is a gradual increase in burial depth from south to north.Additionally,the hanging wall and footwall have different dislocations due to the influence of secondary faults such as Mashan fault,Dongwu fault,and Wenzu fault.However,there is still a general continuity in their East-West distribution.The regional groundwater circulation process is extremely complex.The Taishan rock group,Cambrian,and Ordovician water-bearing rock groups interact with each other through various means such as surface flow discharge,leakage,structural connectivity,and underground runoff.In certain areas of piedmont,karst water exchanges with Quaternary loose-pore water and ultimately discharges through springs or artificial mining.The regional groundwater flow exhibits a unified“four fields”and demonstrates distinct horizontal and vertical zoning characteristics.The boundary between cold springs and geothermal springs is formed along the Donge fault and its extension line,encompassing Wujiabao,Huashan,Zhangqiu and Cicun.The circulation depth boundaries of shallow,medium,and deep flow are roughly divided at 600 m and 1000 m.Cold springs are predominantly characterized by shallow circul
