Using five layer nanjing institute of meteorology land surface process model(NIMLSP)for data on meteorological scientific experiment over the Qinghai Tibet Plateau from May to August in 1979, characteristics of land surface process and energy transport were both simulated for different regions over the plateau for summer season. Simulations of either sensible heat flux or latent heat flux were compared with its calculations from observed data and with measurements of net radiation, soil temperature and soil heat flux respectively. Results show that this model can be applicable to simulation of energy exchange for summer over various underlying surfaces in the Qinghai-Tibet Plateau.
