Abstract In order to study the situation of groundwater resources in Lingyun County of Guangxi, based on the analysis of geological structure, karst development characteristics, water-bearing medium and hydrodynamic conditions, the author evaluated the natural recharge and recoverable resources of groundwater in Lingyun County through precipitation infiltration coefficient method and runoff modulus method in dry season, and analyzed the spatial distribution characteristics of groundwater resources. The results show that the annual average natural recharge of groundwater in the whole region is 112 619.73×10⁴ m³/a, of which the annual average natural recharge of karst groundwater is 69 797.68×10⁴ m³/a, and the annual average natural recharge of bedrock fissure water is 42 822.05×10⁴ m³/a, with 9 840.37×10⁴m³/a of recoverable resource. The karst is well developed in this area, with abundant karst forms. The karst development has certain subdivision in the vertical, of which the elevation span is large, and the overall spatial distribution of groundwater resources is relatively uniform. This research results provide scientific basis for the sustainable development and utilization of groundwater resources in Lingyun County.

Key words： groundwater resource evaluation precipitation infiltration coefficient method runoff modulus method in dry season space distribution of groundwater
