Figures 7 and 8 illustrate the changed and unchanged areas of AHCRs，as projected after 2°C and 4°C warming under RCP8.5，simulated by various GCMs.From the MME statistics（Table 4），given 2°C and 4°C warming relative to the baseline period，the following results emerge.The humid region mainly shrinks，with its area projected to reduce by 13.03%and9.95%，occupying 3.56%and 4.66%of the country，respectively.The sub-humid region considerably expands，increasing by 33.15%and 50.29%，occupying 4.62%and 7.01%of the country for 2°C and 4°C warming，respectively.The semi-arid region also expands，projected to increase by 13.49%and 16.65%，and occupying 3.32%and 4.10%of the country，respectively.The arid region remains mostly unchanged.The AHCR areas of expansion and contraction increase from 2°C to 4°C warming，except for the arid region.According to the MME results，the total area of change in China is projected to increase from 10.17%for 2°C warming to 13.72%for 4°C warming，bringing a further increase of 3.55%.
