GRADIENTS OF DISTRIBUTION OF THE SOIL-PLANT COVER NATURAL PASTURES OF THE SOUTH-WESTERN FERROWS OF ZHETYSU ALATAU

Abstract

The Kaspansky rural district is located in the north of the central part of the Kerbulak district of Almaty region. The territory of the district is located in the southwestern spurs of the Zhetysu Alatau and has an absolute elevation of 1,000 to 2,550 m. The conditions of soil formation in a given territory are subject to the laws of vertical zonality. The following soils are most common here: southern
chernozems, ordinary and less developed middlelands, light brown, ordinary and underdeveloped, meadow light brown, ordinary lowlands, mechanically, the soil is loamy. In the northeastern part of land use, within the limits of the middle mountains, on the black soils of the southern middle-capacity, poaceous-grass hay fields and pastures, grass- poaceous, turf-grass, shruby-sod-grass and other types of pastures are widespread. For the northern middle mountainous part of the territory with a steep slope and poorly developed soils, shrub-turf-grass-grazing grasslands are the most typical, where the shrub layer is formed by wilderness, rosehip, honeysuckle, and in the upper half of the slopes wedge archa into shrubs. In the lowlands and plateaus, light brown ordinary soils became widespread, on which sod grass and grass, forbs and grass, narrowly wormwood-ephemeral vegetation
formed. On slopes with underdeveloped soils, there are fast-growing pastures. Ingeneral, the mountain pastures of the Zhetysu Alatau are in a satisfactory condition at the stage of recovery succession.
