This paper describes the biodiversity of cyanobacteria and microalgae of biological soil crusts(BSC)on bare substrates in different mountain vegetation types at the Northern *** total,we identified 99 algal species from six divisions in all sampled *** species diversity and structure of BSC algal communities show a relationship with environmental factors(altitude,soil p H and humidity,and illumination).Taxonomic diversity of algae decreases along the altitude gradient from mountain meadow to mountain *** and cyanobacteria species from six divisions were identified in meadow communities,five in mountain forests and four in mountain *** observed a positive correlation between species diversity of phototrophic microorganisms and altitude in the forest communities,but a negative correlation in the *** dominant complex of cyanobacterial and algal species in BSC was specific for each type of plant community and was reflective of the habitat *** species diversity and morphological organization of the BSC algae thalli can be used as a criterion for the ongoing assessment of climatic changes in high latitudes and mountain regions.
