The article presents the analysis of monitoring research of soil algoflora of forest and meadow ecosystems in the vicinity of the plant “Maradykovskiy” for the period before the start of its operating and till after stopping its functioning. Specious diversity of forest phytocoenoses algoflora before the start of its functioning accounted for 71 species. After the plant stopped functioning there were found out just 60 species. In meadow phytocoenoses the number is 123 and 95 species accordingly. The number of microphototrophs varies in forest ecosystems from 59.3 to 280.5 thousand cells per 1 g of air-dry soil. Green algae prevail in number (41.3 to 263.3 thousand cells per 1 g of soil). At the monitoring sites of meadow phytocoenoses the index of algoflora varies from 71.6 to 447.1 thousand cells per 1 g, green algae prevailing. The structure of algoflora of the monitoring sites is presented by the soil algae groups Chlorophyta, Bacillariophyta, Ochrophyta, as for species diversity, green algae prevail. Cyanobacteria (CB) are represented in coniferous forest ecosystems by a small number of species, they are rare there, and in meadow ecosystems they account for 29% species. Specious diversity of yellow-green algae and CB also decreased during the period of the plant’s functioning, still it is likely to increase after the plant stopped functioning.
