The article is devoted to the peculiarities of the spatial organization of vegetation on the border of the eastern spurs of the Kuznetsk Alatau and the South Minusinsk basin. Eleven plant community associations were identified during classification. With the help of DCA-ordination, the key ecological factors were identified: precipitation, stony substrate, elevation above sea level. Based on the classification and gradient analysis, the ecological series of plant communities, changing in accordance with the key environmental factors are described. The selected series made it possible to identify the main patterns of plant communities with changes in humidity factors-elevation from meadow steppes with Stipa pennata and larch hemiborial forests at the foot of slopes on leveled areas, to cryophytic tundra steppes and petrophytic steppes with glacial relics in the upper, coldest parts of the ridge. Cartographic models of the upper part of the forest-steppe belt were developed using Sentinel-2 and Resurs-P ...
