In order to investigate the characteristics of karst pipeline in Dongcun, Xinyu, Jiangxi Province, rationally develop and utilize Karst water resources and scientifically protect karst water environment, two kinds of fluorescence tracers, sodium fluorescein and Rhodamine, were selected for quantitative tracing test research on Karst pipeline. The distribution, morphology and hydraulic characteristics of the Karst pipeline through the penetration curve and clarifies the connectivity of groundwater recharge, runoff and discharge characteristics were analyzed. The test results show that Zhangmuqiao water-dissipation cave is connected to Niulang Zhinv cave underground river. The Karst development of the underground river is extremely developed, with large-scale Karst pipeline as the main Karst pipeline. The pipeline is single-like and the underground runoff path of the main Karst pipeline is short. Some parts of the groundwater has the characteristic of pressure-bearing. The direction of the underground runoff is from east to west. Its flow rate is fast, and so is the solute migration rate. There’s small possibility of other drainage outlets. However, there is no hydraulic connection between the Zhangmuqiao water-dissipation cave and Shenniu cave underground river outlet.
