Belt and zone structure of flora of Sydinskaya foothill and Pribaytaksky meadow steppes (Krasnoyarsk region)

According to climatic division into districts the territory is related to moderate humidified belt. Ac-cording to the system of zone and sector distribu-tion of vegetation Sydinsky foothill and Pribaytak-sky meadow steppes belong to subboreal biocli-matic zone, being located on the border of West Siberian and West Asian (continental) and East Central Asian (sharply continental) sectors. The set of ecological and geographical groups participating in addition of flora allows to estimate zone features and to characterize the structure of vegetation cov-er in climatic and orographical conditions of steppe, and also to understand the genesis of flora and its anthropogenous trasnformation. The main part of areas of montane types is concentrated in moun-tain systems. In flat territories plants which areas occupy extensive territories of watersheds are widespread, but sometimes come on mountain heights. All types of Sydinskaya foothill and Pribay-takskaya meadow steppes depending on belt and zone features are subdivided into 10 belt and zone groups: Alpine, Arctic and Alpine, montane and forest (mountain and taiga), montane and steppe (mountain-steppe), forest, forest-steppe, nemoral, steppe, plurozonal (azonal) and adventive. The heterogeneity of belt and zone structure of flora of Sydinskaya foothill and Pribaytakskaya meadow steppes at present stage is characterized by flat forest complex (28.9 % of flora structure) the varie-ty is brought by forest-steppe (17.8 %) and climatic caused steppe and mountain steppe (18.5 %), plu-rozonal (18.9 %) by groups. Arctic and Alpine, Al-pine and montane (in total 12.8 %) groups of high-rise complex give originality to flora of steppes. In the Sydinskaya foothill steppe azonal complex of types in connection with the arrangement in real steppes of valleys of the rivers and pine-forest lakes of forest type with boggy meadows is re-vealed.
