摘　　要：济南岩溶区水化学的主控地层为富锶的古生代海相碳酸盐岩。在地下水营力的作用下锶进行迁移转化,其分布特征具有重要的水文地质意义。笔者利用岩溶水中的微量元素Sr的含量大小及其分布特征,从水文地球化学的角度出发,揭示了其水文地质意义:通过分析Sr元素含量的分布特征及迁移规律,验证了济南泉水补给的多源性及"一碗水"观点;通过刻画Sr/Ca比值的分布特征,探索了济南泉域岩溶水的径流规律,并结合TDS浓度梯度特征对其可信度进行了验证。为济南泉水及其他地区岩溶水的研究提供了一些有益的启示。The main control strata of Jinan karst area are the Paleozoic marine carbonate rocks of strontium rich. The distribution characteristicsof Strontium ingroundwater has important hydrogeological significance for migration and transformation of strontium under the action of groundwater stress. Under the premise of mastering the basic background of the study area, the author reveals the rich connotation ofhydrogeologica from the point of view of Hydrogeochemistry by using trace element Sr: By analyzing the distribution characteristics and migration law of Sr element content, the author verifies that the spring water in Jinan is supplied by a variety of sources;By depicting the distribution characteristics of Sr/Ca ratio, the flow pattern of karst water in Jinan spring basin is Researched. Finally, the reliability was verified by comparing the TDS concentration gradient. This study provides some useful enlightenment for the study of the karst groundwater in Jinan and other areas.
