Abstract

The article discusses the potential of soil moisture in permafrost alas swamp, meadow and steppificated soils, differing in nature and moisture degree.

The magnitude of the soil moisture potential grows from the center to the periphery of the alas and during the growing season varies over a wide range. In the soils of the lower and middle zones, capillary movement of moisture prevails, and not only vertical, but also horizontal inflow and outflow of moisture is observed. In the soils of the upper belt there is no lateral inflow of capillary moisture, and the degree of soil moisture is entirely dependent on the duration and intensity of precipitation.

The knowledge of features for moisture potential distribution in space and time will allow us to understand the nature of hydrothermal belts of alas basin formation.

Keywords
