The aim of the study was to determine the effect of oil pollution on the transformation of algocenoses of water-ground ecotone. The species composition, abundance, occurrence of cyanobacteria and algae in water-ground ecotone under the influence of oil pollution has been studied. A comparison of the algoflora of different ecotone sites was made taking into account the nature of the higher plants. Sixty-five taxa of algae were identified with a rank below the genus belonging to the 4th divisions. The division dominant in the number of species is Bacillariophyta (37%), Cyanoprokaryota (Cyanophyta) (31%), Chlorophyta (27%), Xanthophyta (5%). The leading families were Pseudanabaenaceae, Phormidiaceae, Cocconeidaceae. Among the genera, the genus Leptolyngbya is in first place. The littoral zone of the lake was dominated by diatomic algae. A wide range of species of cyanobacteria and green algae were observed in soil samples, leading families and genera by species occurrence were members of the families Nostocaceae, Pseudanabaenaceae. Environmental analysis has shown that hydrophilic and edadophilic species belonging to P-, Ch-, CF-, C and B-life forms play a significant role in the formation of soil algae communities. The nature of the higher plants is less than oil pollution determines the composition of the algoflora. With the emergence of oil contamination in the ecotone, the number of cyanobacteria and algae, the survival rate of soil algae and, to a lesser extent, benthic species is reduced.
