The hydrological models used in Land-surface models are briefly introduced. The physical processes of land-surface hydrological processes and the developing status of land-surface hydrological model studies in China and abroad are briefly summarized. Land-surface hydrological models which are coupled with climate models are reviewed. The weakness and possible solutions in land-surface hydrological process modeling and coupling process studies are pointed out. The developing directions of land-surface hydrological processes are discussed. It is pointed out that more attention should be paid to both infiltration excess, saturation excess and snow models, and the large-scale land surface hydrological model should be developed based on tradition hydrological models.
