Abstract
The aim of the paper is the floristic analysis at the Krasnoyarsk forest-steppe pine cenoses. This problemrequires detailed research under the constant anthropogenic pressure. A flora inventory was carried out, vascular plantsspecies composition was determined. As a result, a summary of the flora was compiled, which includes 126 species from107 genera, 46 families, 6 classes, 5 divisions. Floristic analysis was carried out by the method of specific flora, taking intoaccount herbarium materials. The taxonomic, chorological, zonal, ecological, biomorphological flora structure featureswere determined based on the analysis of floristic data. The protected taxes have been identified. The peculiarities ofvegetation cover species composition are marked on the basis of the comprehensive flora analysis. The authors madethe conclusion that mesophytes of the light-coniferous and forest-steppe belt-zone groups with the Eurasian and EuroSiberian ranges predominate in the pine cenoses flora at the Krasnoyarsk forest-steppe. The most part of species havethe life forms hemicryptophytes and cryptophytes. Species to be protected have been discovered: Cypripedium calceolus,C. guttatum, C. macranthon, Neottianthe cucullata.
