Anаlysis of the data obtained in the investigation of humus profiles of mountain-chestnut soil of the complex catena situated in the limits of Khemchik dry steppe region of the Central Tuva Depression is presented. It is shown that the characteristics of humus profiles depend both on the slope exposure and on the position of soil over the catena. The humus profiles of soils clearly fix all the changes of the ecological conditions of formation and functioning of soil even in the case when they are not depicted in the morphological appearance of soil. The data obtained may serve as the starting point for supplementary monitoring of the behavior of soil at the slopes and for revealing the variability of the soils of local level under the effect of changing natural environment.
