This paper briefly introduced the groundwater conception model and its application, and emphatically introduced the es-tablishment of correlation models and neutral network models for groundwater level prediction in alluvial fan porewater aquifer ofdashahe-cihe region at Daqinghe groundwater aquifer system in Hebei Province. Isues such as replenishment of precipitation forground water,mining yield of groundwater, boundary condition and initialization condition in groundwater prediction were discussed.Advantage and disadvantage of conception model and correlation model were also compared.
