| 摘 要： | 晋祠泉和兰村泉是山西著名的岩溶大泉，受自然条件变化和人类活动的影响，两个泉于20世纪末相继断流。针对山西省政府提出的要使晋祠、兰村泉水复流的生态修复目标任务，文章在泉域水文地质调查基础上，就泉水复流密切相关的四个关键性岩溶水文地质条件问题开展研究并提出了新认识。核实了目前划定的晋祠—兰村泉域边界，依据最新资料对现行的晋祠、兰村泉域边界提出了7处修正，修改后晋祠泉域面积由2 030 km2变为2 713 km2，兰村泉域面积由2 500 km2变为2 614 km2。汾河二库在蓄水后库区的主体部分划归到晋祠泉域而非兰村泉域，其渗漏补给是造成近年来晋祠泉域区域岩溶地下水位大幅回升的主要原因。确定了晋祠泉域内盘道—马家山断裂带是一个岩溶水强富水带，也是岩溶地下水从北部中、上寒武统含水岩组向南部中奥陶统含水岩组的转换带。圈定了晋祠泉域:玉门河南峪村—杜儿平煤矿东侧—官地矿与白家庄矿交界处—龙山—明仙村东—晋祠泉的岩溶地下水强径流带。这些认识是开展晋祠—兰村泉域岩溶地下水资源评价、地下水开发管理和保护的基础，更是制定晋祠、兰村泉水复流方案的重要依据。

| Abstract: | The Jinci spring and Lancun spring are the famous springs in Shanxi province. Due to the changes in natural conditions and the effect of human activities, hydrogeological conditions of the catchment area of the springs have changed, and they became zero-flow at the end of the last century. Based on the previous research results, current investigation and hydrogeological drilling data, new understanding of hydrogeological conditions of the groundwater systems of the Jinci spring and Lancun spring are put forward through analyses of the karst groundwater flow field. The boundaries of the groundwater systems of these two springs are corrected, with seven differences compared with the boundaries delimited by the Shanxi government. According to the latest boundary, the catchment area of the Jinci spring increases from 2 030 km2 to 2 713 km2 and that of the Lancun spring increases from 2 500 km2 to 2 614 km2. The Fenhe reservoir, which used to belong to the Jinci spring system, has the leakage recharge to the Jinci spring system. This is one of the main causes of the increase in the karst groundwater levels in the Jinci spring spring. The Pandao-Majiashan fault zone is found to be a groundwater-enrichment region. It is also a transfer zone, in which the karst groundwater in the Cambrian aquifer flows to the Ordovician aquifer. The strong groundwater flow zone along the Nanyu-Duerping Coal-the junction of Guandi Coal and Baijiazhuang Coal-Chiqiao-Jinci Spring is also identified in the Jinci spring system. The results can provide a scientific basis for groundwater resources assessment and the reasonable exploration of the karst groundwater and the implementation of programs of reflow of the Jinci spring. |
