HUMUS CONTENT OF SOIL IN ALTAI MOUNTAINS AND ITS ENVIRONMENTAL CONDITION

The article describes the function of soil fertility humus performs; the function is important for ecosystems, biosphere and anthroposphere as well. Humus content of soil is revealed in different ways when experiencing anthropogenic influence in the areas differed in climate characteristics. The paper reveals necessity in appropriate estimation of relation between humus content of soil and environmental conditions. The possibility to forecast humus substances reaction by means of taking into consideration the effect goal and changing conditions of the system operation results in urgency of environmental conditions for the features of humus content of soil. The paper investigates the soils of different altitudinal belts moistened in arid, humid and balanced ways. The authors characterize humus content of soil in Altai Mountains which is very complicated area for agriculture. They study the fundamental climate characteristics of the territory; reveal the results of relation between humus soil content and climate characteristics; represent the regression models of Сгк: Сфк relation and moistening; and reveal regression equation on the basis of altitude. The regression models effectively describe the data which is proved by statistic criteria and diagrams. The regression equations can be applied when estimating environmental conditions of relation between humic components and in order to estimate them in natural environment influenced by natural and anthropogenic factors.
