As a branch of hydrologic cycle, land-surface hydrological processes are nearly relative to atmospheric circle by water and energy exchange between land-surface and atmosphere. Land-surface hydrological processes are not only the main participants in climate change but are effected by the change. The capacity of understanding and simulating the land-surface hydrological processes in climatic model is the premise to accurate climate prediction. The development of landsurface model is briefly introduced. The parameterization of land-surface hydrological processes is reviewed in overall from bare soil evaporation, plant evapotranspiration, soil wetness, drainage and runoff. There are still some uncertainties lying in the land-surface schemes. The main issues on hydrological processes parameterization include soil layers, soil layer depth, rooted area distribution; the representation and transplantation of parameters; observed data; and parameterization of runoff. The importance of runoff in landsurface schemes is analyzed; the weakness of runoff parameterization is pointed out; the study of runoff simulation in land-surface model is introduced; and the research focuses in the future are discussed.
