Description :
Permafrost in Central Asian is present in the Qinghai-Tibet Plateau in China, the Tien Shan Mountain regions in China, Kazakhstan and Kyrgyzstan, the Pamirs in Tajikistan, and in Mongolia. Monitoring of the ground thermal regime in these regions over the past several decades has shown that the permafrost has been undergoing significant changes caused by climate warming and increasing human activities. Results and discussion of the measured mean annual ground temperature (MAGT) at a depth of 6 m in these regions during the International Polar year (2007-2009).
