Based on the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emission Scenarios (SRES) A2 and B2, and by using the Regional Climate Model (PRECIS) and grassland SPUR model, the changes of grassland productivity in Northern Tibet in 2071-2100 were simulated. It was predicted that under scenarios A2 and B2, the aboveground biomass of all kind grasslands in the regions, where temperature raised, total solar radiation decreased, and precipitation increased, would be increased, while that of Kobrezsia pygmaea grassland in the regions, where precipitation decreased, would be decreased. Our results suggested that the grassland productivity in Northern Tibet might not benefit from CO2 fertilization.
