The comparison of taxonomic phytoplankton's structure in the researched rivers with the one of planktonic algae in Dnieper estuaries allowed indicating the high similarity not only on the level of groups and classes but on the level of dominant families and species. But nevertheless we indicate the fewer roles of desmids; however rivers with the distinguished marshy nutrition as a rule have the great amount of conjugates. This indicates that on the modern stage of development of their ecosystems the succession passes in the terms of natural features domination. The phytoplankton content of researched small rivers differs sufficiently; therefore it proves its originality. The executed floristic analysis allowed separating 3 groups of planktonic complexes: with dominating diatomic, green and practically equal number of species of green and diatomic algae. Rivers of the first type are characterized with high concentrations of iron. All rivers show the high concentration of nitrate form of nitrogen, especially rivers of the second and third groups. Upon increasing of coloring and anthropogenic impact the decreasing effect of species abundance and intensity of geni with species was observed. 5 scientific works were published, including 4 theses of the Ukrainian scientific-practical conference, 1 thesis of reports on the International scientific-practical conference. Scientists took part in 3 conferences: 2 Ukrainian ones and 1 International.
