By using environmental isotopes and hydrochemical components as tracers to survey water cycling, this paper revealed the groundwater cycling characteristics in Liujiang Donggong River Basin. Based on the field survey, designing and assigning the location of sampling points, collecting and testing atmospheric precipitation, surface water and groundwater samples, comparing different period chemical characteristics of water samples, combining hydrogen and oxygen isotopic composition, the conditions of recharge, runoff and discharge in different kinds of groundwater were determined. Results showed that groundwater originating from Fujunshan group limestone aquifer with thick layer in the Cambrian system was the most significance of water supply in Donggong River Basin; karst water flow direction was from north to south, which was in line with the regional karst water flow of Liujiang Basin. It received precipitation infiltration recharge from the northern mountains. In the wet period the discharge mainly included two forms: one was the spring discharge through Quaternary aquitard in Dongbuluo village, the other was in the form of groundwater runoff discharge to Donggong River in the northern margin of the basin to the west of Dongbuluo village. The bedrock fissure water followed, and its distribution had the strong inhomogeneous anisotropic characteristics. Compared to the Man-Mao group shale in the northwestern mountains of basin, the water quality in granite fissure from the northeastern mountains of basin was good, and had the highest recharge head, stable recharge source, and shorter recharge route. Meanwhile, artesian zone existed in Lizhuang and its vicinity. The research results can provide the scientific basis for the development and utilization of local water resources.
