Rusanov A.M., Eliseeva M.V. THE EFFECT OF ASYMMETRIES ON WATERSHED AREAS VEGETATION COVER OF STEPPE OF THE URALSSoils are a major component of the natural environment, and their properties reflect the complex interactions of the biosphere with the lithosphere. Soil processes affect vegetation and fauna, form a plant Association, the active form of the upper shell of the globe. For the Orenburg region one of the leading factors of soil formation which is a relief. Since river valleys of the Steppe near the Urals and their tributaries are characterized by a distinct asymmetry that is manifested in neravnomernosti interfluvial uplands, this in turn affects landscape complexes, which are formed on the slopes of different expositions. The paper presents the results of a morphological study of soil condition and vegetation cover of the Steppe near the Urals. The study was carried out in 2015 on the watershed plateau, Northern slopes and southern exposure. Thus, it should be noted that in the vegetation groups of the North slope is dominated by feather-grass vegetation, and on slopes South of fescue. The study of projective cover on the slopes showed that the slopes of Northern exposure have higher projective cover than the southern slopes, and is 75–80 %, 60–65 % respectively. This is also reflected in the ratio of underground to above-ground biomass on the Northern slope of the ratio of underground to above-ground biomass is higher than in the South.Key words: the asymmetry of the landscape, vegetation, projective cover, usual black.
