This article sheds light on the role diatomic algae in soils play in the assessment of bee farm and nearby territories in four soil and landscape zones in Samarskaya Oblast. The community of diatomic algae is characterized by low species diversity, of which 23 taxons were found. The most often found species are represented by Hantzschia amphioxys (Ehrenberg) Grunow in Cleve & Grunow and Luticola mutica (Kützing) D.G.Mann in Round et al. The maximum of phyla (18) were found in the buffer (transient) zone; in the wooded steppe zone, 11 species were recorded; in the steppe – 2 species, and in the dry steppe zone no species of diatomic algae were found. The qualitative and quantitative characteristics of diatomic algae communities in various biotopes depend on the natural and climate features of a territory and the degree of the anthropogenic impact on the soil and vegetation, which is proved by the fact that high species wealth signifies that the ecosystem is stable and resilient to the changing conditions in the environment, while poor algal flora is less resilient due to the lower degree of diversity.
