摘　　要：示踪试验是客观认识地下河管道空间结构的有效手段之一,其成果可成为地下河开发利用的重要依据。通过对以食盐为示踪剂,以摩尔法为检测方法得出的巨木地下河出口水质中Cl#体积质量历时曲线的分析,认为该地下河具多支、网络状特点,系统内含水介质以管道、廊道、裂隙及溶潭的组合为特征,具有较强的调蓄能力,具备筑坝成库条件。Tracer tests are an effective method to understand the spatial structure of underground river pipelines,whose results can be important evidence for the development and utilization of underground rivers. Taken salt as tracer,this study obtained the duration curves of Cl-from outlet of the Jumu underground river with the molar method. It is indicated that,this underground river is featured by many branches,with a network shape; water-bearing media in the system are characterized by a combination of pipeline,corridor,fracture and puddle,with a strong storage capacity,and this system has good damming and reservoir-forming conditions.
