Abstract：Lingshui Spring is a typical tectonic karst spring in Guangxi and its spring field is widely distributed. The spring has the characteristics of multi-outlet, high flow and dynamic stability. In recent years, the outlet flow of Lingshui Spring has showed a decreasing trend, and the water has been slightly polluted, which caused the local government's high attention. In order to find out the characteristics of water-bearing medium and recharge area in Lingshui Spring, the authors studied the distribution characteristics of the karst pipelines in Lingshui Spring through ground investigation, geophysical prospecting, drilling and groundwater tracing. And they also defined the recharge area of Lingshui Spring. The results showed that the structure of the karst pipelines in the upper reaches of Lingshui Spring was reticular. The scale of the pipelines was not large, and the pipelines showed a concentrated band distribution. The northern part of the study area was the main recharge area of the spring, and the typical concentrated runoff band was about 8 km long and 200-700 m wide. According to the altitude effect of the isotope, it was calculated that the recharge altitude of the Lingshui Spring and the result was about 496 m, which was close to the investigation results. This study could provide some support for the development and protection of groundwater resources in Lingshui Spring.
