Abstract
This paper discusses the main indicators diversity of vegetation in key areas of the northern macro slope of the Western Tannu-Ola Range. The degree of forest cover and vegetation fragmentation were estimated using Landsat-TM/ ETM+/OLI images for June 25, 1992, June 18, 1998 and June 24, 2015 in QGIS using the plugin Landscape Ecology. The Simpson index shows of increasing biodiversity in different altitudes. The results showed that with increasing climate warming in the region and maintaining this trend, the proportion of dark coniferous forest at all altitude levels (foothill, mid-elevation and high-elevation zones) will increase. And this led to a decrease in the fragmentation of the forest cover of northern macro slope of this range.

Summary
Within the framework of “The Biodiversity Conservation” were recommended to assess ecosystem diversity. For assess ecosystem diversity it was proposed to use the ratio of the areas of different forest types relative to the total area, as well as the fragmentation of forest cover [1]. Among the priority tasks is the assessment of mountain biodiversity. The impacts to climate change in territory of Central Asia are manifested noticeably. The mountainous ecosystems of Southern Siberia are remarkably sensitive to the vulnerable environment conditions. The most serious among them are the processes of change in the southern boreal forests. Central Asia is characterized a variety of plant and climatic conditions. Taking into account and assessing the diversity of forest communities in the republic remains a problem due to the limited availability of a significant part of the region
