摘　　要：本文研究济南岩溶排泄区地下水化学成分的形成。先用Cl-和NO3-浓度作为示踪剂分析补给区的大气降水输入,鉴别出西郊和平安店排泄区地下水没有被明显污染,市区和东郊排泄区地下水受到明显污染,污染主要来自当地浅层地下水或近地面土层。之后,利用西郊排泄区的测试数据进行了横向径流带的水-岩作用定量分析,与示踪剂研究结果一致,市区和东郊排泄区地下水被明显污染,同时提出地下水在径流过程中发生脱白云石化过程的趋势线。Formation of hydrochemistry components in discharge areas in Jinan was researched. Inert chemical tracers such as C1^- and NO3^- were used to be analyzed atmospheric input from recharge areas. The result showed that groundwater in Xijiao and Ping＇ andian recharge areas was not polluted clearly. Groundwater in urban was polluted distinctly by local shallow groundwater and surface soil. Then, water-rock interaction along the horizontal flow pathway was quantificationally analyzed through hydrochemical data from Xijiao. Compared to tracer result, consistent result appeared that groundwater in urban was polluted obviously. Meanwhile, trendline of Dedolomitization process was put forward during groundwater movement.
