英文摘要	Six earth system models from phase 5 of the Coupled Model Inter-comparison Project (CMIP5) are evaluated over Tibetan Plateau (TP) by comparing the modelled temperature (Tas), precipitation (Pr), net primary production (NPP) and leaf area index (LAI) with the observed Tas, Pr, International Geosphere Biosphere Program (IGBP) NPP and Max-Planck Institute for Meteorology (MPIM) LAI in the historical, and then we analysed the change of climate and carbon cycle and explored the relationship between the carbon cycle and main climatic drivers in the historical and representative concentration pathway 4.5 (RCP4.5) simulation over TP. While model results differ, their region spatial distributions from 1971 to 2000 agree reasonably with observed Tas, Pr and proxy LAI and NPP. The climatic variables, LAI and carbon flux vary between two simulations, the ration of NPP to gross primary production (GPP) does not change much in the historical and RCP4.5 scenarios. The linear trends of LAI and carbon flux show an obvious continuous increase from historical climatic period (1971-2000) to the first two climatic periods (2011-2040; 2041-2700) of RCP4.5, then the trends decrease in the third climatic period (2071-2100) of RCP4.5. The cumulative multi-model ensemble (MME) net biome production (NBP) is 0.32 kg Cm-2year-1during 1850-2005 and 1.43 kg Cm-2year-1during 2006-2100, the TP is a carbon sink during the historical scenario, and TP will uptake more carbon from atmosphere during 2006-2100 than 1850-2005 under RCP4.5 scenario. LAI, GPP, NPP, Ra and Rh appear more related to the Tas than Pr and Rsds, and the Tas is the primary climatic driver for the plant growth and carbon cycle. With the climate change in 21st century under RCP4.5 scenario, Tas still is the primary climate driver for the plant growth and carbon cycle, but the effect of temperature on plant growth and carbon cycle gets weaker. 2015 Royal Meteorological Society.
