The daily climate data for 1981-2000, and the vegetation type data as well as the soil texture data were used as the inputs of Atmosphere-Vegetation Interaction Model (AVIM2) to simulate the spatial and seasonal surface energy fluxes of Tibetan Plateau with the resolution of 0.1°×0.1° grids. The results indicate that the annual mean surface net radiation flux decreases from 100 W/m2 over southwestern to 70 W/m2 of eastern plateau. The simulated latent heat flux in the forests of southeastern plateau is strong, whereas the sensible heat flux in that area is weak. From southeastern plateau to west and to north, the estimated latent heat flux decreases gradually while the sensible heat increased gradually. This tendency is more significant in summer. In winter, except for the southeastern area, the simulated surface energy fluxes over the broad area of plateau are low.
