Water-heat process in the Tibetan Plateau is significant to global change,and soil moisture and soil temperatures are the key factors of simulating water–heat process.In this paper,a water and energy balance macro scale hydrological model was used to compare the simulated with observed at the step of 1 hour during 399 days in Tuotuohe.The results of meadow evaporation,short-wave radiation, and net radiation were discussed.It is revealed that the evaporation of alpine meadow is the main part of total evapotranspiration of alpine meadow.The total evaporation all the year round is equal to that observed in the Urumqi River area.The simulated daily short-wave radiation is in some sort greater than that observed in winter,whereas the simulated daily short-wave radiation is nearly equal to the observed one,and the fluctuation in a day of simulation is less than that of observation due to daily precipitation input in summer.The simulated yearly net radiation is near to the research result of reference\.
