Abstract

The purpose of the paper is the floristic analysis of shrub meadows, which make a significant contribution to the vegetation cover of the Republic of Khakassia. This problem requires detailed research under the increasing anthropogenic pressure on meadow phytocenoses. A flora inventory was carried out, the higher plants species composition was determined. As a result, a summary of the flora was compiled, including 80 species from 60 genera, 31 families, 5 classes, 4 departments. Field research was carried out using the route method. We took into account herbarium materials. The taxonomic, chorological, zonal, biomorphological, ecological flora structure features were determined based on the analysis of floristic data. The peculiarities of vegetation cover species composition are marked on the basis of the comprehensive flora analysis. The authors made the conclusion that mesophytes of the light-coniferous and forest-steppe belt-zone groups with the Eurasian, Euro-Siberian, Holarctic and North Asian ranges predominate in the flora of meadow cenoses of the Republic of Khakassia. The most part of species are hemicryptophytes and cryptophytes.
