Abstract：By summarizing hydrogeological conditions and characteristics of Fengpei Plain area, the authors has analyzed the exploitation and utilization conditions of groundwater and potential water source. And the available resources of karst water in Huaqi uplift were calculated and the feasibility of karst water utilization was discussed. The results show that the main groundwater level in the study area is middle and upper Pleistocene pore aquifer and Neogene-Lower Pleistocene pore aquifer, which have already formed two super large funnel areas of Chengguan of Fengxian-Sunlou-Changdian and Peixian-Longgu, with the total area exceeding 750 km2 , causing large ground subsidence area. Huaqi uplift is the karst water-rich area, with the total recoverable resources of 667.51×104 m3/a. This area can be regarded as potential water source area for further groundwater exploitation. Excess exploitation of karst water can cause problems such as land subsidence, karst ground collapse, so long-term monitoring of karst water exploitation in the future and reasonable usage of groundwater are necessary. The karst water in Huaqi uplift is close to the urban area with large volume and good quality, and it is relatively easy to develop, which means it has considerable economic value.
