Dynamics of Сhange of the Seasonally Thawing Layer in the Conditions of Industrial Development of the Yenisei North

Abstract

The conducted researches show that depth of thawing of the seasonally thawing layer (STS) in the conditions of industrial development is influenced by a number of factors: existence of a vegetable cover, moisture content of a surface of the soil, familiarity of the territory. For preservation of natural borders of depth of thawing of STS and prevention of development of a water erosion on tundra lands of the Yenisei North with approach of positive temperatures it is necessary to observe a number of measures: the maximum aspiration to maintaining physical properties of the soil and the modes of a korneobitayemy layer of the tundra; minimizing operation of the caterpillar equipment, use of the special equipment with the facilitated weight (trekola); the ban on drives of the equipment on rekultivirovanny sites; accounting of the steepness of slopes at earthwork and construction of industrial facilities; precautionary measures in case of threat of emergence of prerequisites of a water erosion, timely holding remediation actions, etc.
