Carbon cycle review of the permafrost in Qinghai-Tibet Plateau

The permafrost in Qinghai-Tibet Plateau is the biggest thickness and the broadest area in middle and low latitude in the present world, the permafrost ecosystem is one of main ecosystem, the carbon cycle of permafrost ecosystems plays an important role in the global carbon cycle. Firstly, reviewed research progress of the permafrost and temperature changes and reasons for the differences, and subsequently summarized permafrost carbon emissions and sinks, but so far it is still unclear how the rising temperature and changes in permafrost influences soil organic carbon dynamically there, thus, we must study the Tibetan Plateau on the entire region avoiding inconsistencies in the local area of permafrost distribution, and long-term observations and experiments should be conducted in order to explain the relationship of climate changes and permafrost and soil organic carbon cyclical.
