Summary

Two models are used to simulate the high-altitude permafrost distribution on the Qinghai-Xizang Plateau. The results show that the permafrost on the plateau will not change significantly during 20-50 years, the percentage of total disappeared area will not be over 19%. However, by the year 2099, if the air temperature increases by an average of 2.91°C on the plateau, the decrease in the area of permafrost will exceed 58% - almost all the permafrost in the southern plateau and in the eastern plateau will disappear.
