RT Journal Article ID 792ab2d24f30ea7d A1 Pilipenko, Yu. V. T1 Ecological-trophic Classification of the Small Reservoirs Used for Different Purposes JF Hydrobiological Journal JO HYD YR 2010 FD 2010-02-25 VO 46 IS 1 SP 3 OP 11 K1 small reservoirs K1 abiotic and biotic parameters K1 classification levels and categories K1 degradation of hydroecosystems AB The ecological-trophic classification of the small reservoirs used for different special purposes based on use of the limited number of abiotic (depth, flow, water transparence, content of biogenic elements, mineralization, pH) and biotic (overgrowth of macrophytes, phytoplankton biomass) parameters has been proposed. Proposed system of classification enables to carry out integrated certification of these water bodies, to carry out ecological valuation of the separate water areas, to obtain appropriate data on their ecosystems degradation.
