TO THE TYPOLOGY OF LAKES BY THE COMPOSITION OF aquatic AND semi-aquatic VEGETATION IN THE SOUTH OF THE OB-IRTYSH INTERfluve (West siberia)
The main botanical types of the Ob-Irtysh interfluve lakes were revealed: 7 groups of types and 16 types based on the materials of hydrobotanical studies in Novosibirsk Region. A brief literary review of approaches to the botanical classification of lakes is carried out. It is shown that the most informative classification clusters were identified by the statistical analysis of the aquatic core of the flora. The coenotic composition is a less reliable criterion due to the anthropogenic fallout of a number of cenoses of aquatic vegetation.
