Аннотация: Based on the biome concept in biogeography and the ecological-geographical approach to the analysis of biodiversity, a regional assessment of the Southeast Altai-Tuva orobiome, which is unique for Russia, is given. The orobiome is considered as a reference unit for the inventory and analysis of the ecosystem and biotic diversity of mountain areas. The characteristics of bioclimatic indicators characterizing the originalityof the desert-steppe orobiome of the Subarid class of zonality types and its altitudinal zones are given. The altitudinal structure of the vegetation cover is revealed, in accordance with which the spatial differentiationof flora, plant communities, and ecosystems as a whole is formed. A quantitative assessment of floristic (about 1400 species of vascular plants) and phytocoenotic diversity by zones (nival, desert-tundra, foreststeppe, and steppe) is given. The features of the spatial structure of the diversity of communities in the conditions of a mountainous territory are revealed.
