RÉSUMÉ

Spatial and temporal distribution of the structural and functional indices of phytoplankton development was studied in the additional net of the Kiev section of the Kanev Reservoir in the years differing in their hydrometeorological conditions. A total of 260 species and infraspecific taxa of algae of eight divisions was identified. In winter phytoplankton was characterized by inverse vertical stratification, in summer it was direct, whereas in spring and autumn its distribution over the water column was uniform. A direct relationship was established between the species diversity of plankton algae and water temperature, which is described by linear function. Under abnormal hydrometeorological conditions, the structure, numbers, and biomass of phytoplankton, and also the complex of dominant species, differed from those typical to water bodies of the additional net of the Kiev section of the Kanev Reservoir.
