ABSTRACT: Algal-cyanobacterial communities, soil nano- and microfauna, and mycelium of micromycetes
were studied in soils of an administrative district of Moscow. To characterize the habitat conditions
of microbiota in the soils of different functional zones of the city, the acid-base conditions
and the contents of exchangeable and water-soluble nitrogen, mobile heavy metals, and soluble
salts were determined. The diversity of species of algal-cyanobacterial communities, the composition
of the dominant species, the proportions of different ecological groups of diatom algae, the
diversity of soil nano- and microfauna, and the abundance of colorless and colored mycelium in
the urban soils were characterized. The analysis of these parameters showed that the degree of
technogenic impact on soil microbiota decreases in the following sequence of functional zones of
the city: industrial > traffic > residential > recreation.
