摘要

16 coenofloras are recognized within the flora of Kyiv Plateau in Russia, arranged in 8 groups and 5 types. A coenoflora acts as a system of alpha-biodiversity and an element of beta-biodiversity of the flora. Results are presented of comparing thecoenofloras by their taxonomic and ecological structure using the cluster analysis. The taxonomic structure reflects a transitional character of the Kyiv Plateau flora, i.e., from typical sylvatic nemoral Middle-European floras to forest-steppe zones. Amplitudes of different ecological factors were determined for each coenoflora on the basis of obtained phytoindication indexes. Edaphic factors (soil humidity, carbonate, nitrogen and salt content, soil acidity) proved to be key factors affecting distribution of the coenofloras. Species distribution in the coenofloras by the total effect of anthropogenic factors (hemeroby) shows that they mostly belong to ecotopes with weak or periodically direct anthropogenic effect.
