Abstract. As a geographical location, Altai-Soyon eco-region is located to coincide basically with the border of great physiographic realm of Altai-Soyon. Its great part is Altai mountain range and it covers an area of 248900 square km transferring area of Russia, Mongolia, Kazakhstan and China. From this, Mongol-Altai mountainous district (terrain) covers an area of 160000 sq.km.

Mongolia has the fifth largest permafrost area after Russia, Canada, China, and the United States [Tingjun, Zh et al. 2006]. Mongolia is located in the southern fringe of the Siberian permafrost region, where permafrost shows significant spatial variations in the extent and ice content. Since, permafrost in Mongolia is at a temperature close to 0°C, and thus thermally unstable [Sharkhuu, 2008]. In Mongol-Altai mountainous area, the active permafrost is spread alongside with the high altitude natural order and the permafrost is melting rapidly by influencing the current climate warming. It is clear that permafrost phenomena are happened mostly in the Mongol-Altai mountain range and these are main factors which are shown the climate warming.
