Study on the characteristics of groundwater recharge and discharge and groundwater balance. The evaluation of groundwater resources and the rational development and utilization of groundwater resources. Are of great significance. The influence of each equilibrium factor on the submersible brine aquifer is analyzed by water equilibrium method. The main recharge items of aquifer include precipitation infiltration

atmospheric condensate infiltration and lateral runoff of boundary groundwater. The main discharge items are water surface evaporation and boundary lateral runoff. The calculated results show that the total recharge of the submersible brine aquifer is 2 722×10
