Abstract
The classification of vegetation of shrub steppe communities in the Selenginskoe Midland performed by using florogenetic approach based on the results of cluster analysis of coenofl oras. The received florocoenotypes of shrub steppe reflects the genetic variety of a territory. Are allocated: florocoenotyp Gemixerophyte (nemoral) shrub of the Dauro-Manchurian fratria ( Armeniaca sibirica formation); florocoenotyp Steppe with subtypes Gemixerophyte shrubby steppes of the Altai-Mongolian fratria (a formation of Cotoneaster melanocarpus , Caragana pygmaea ) and Ural-Siberian fratria (a formation of Spiraea media , Pentaphylloides fruticosa ); Xerophyte shrubby steppes of the Altai-Mongolian fratria (a formation of Spiraea aquilegifolia); florocoenotyp Tall grass communities with a subtype Gemixerophyt shrubby of the Central Asian fratria (Caragana spinosa formation). The article includes a brief characteristics of vegetation formations.
