Abstract: Based on the hydrogeological mechanisms and conceptual model of groundwater system in the Fuqing Plain, a three-dimensional numerical model for recoverable resource evaluation of groundwater source was established for the first time. According to the requirements of water level control for groundwater aquifer, this study presents prediction for the recoverable resources of groundwater in this area. Source areas of emergency groundwater have also been defined in relatively water-enriched areas and the amount of emergency recoverable water was estimated. The results show that the recoverable resources of underground water in the Fuqing plain are 1 189.35×10⁴ m³/a. Two emergency underground resources, which were also defined at Xieyanshan in Yangzi and Tangtoucun in Longshan, have a total recoverable resource of groundwater of 246.375×10⁴ m³/a, providing some references for construction of groundwater emergency water sources in the Fuqing Plain.
