Transformation of soil and land resources of the Middle Siberia in the conditions of climatic changes

Abstract

The paper describes the fields of transformation of soil and land resources of the Middle Siberia as the result of long-term climatic changes. The description of soil and land resources is given. The climatic changes have been evaluated for the period from 1919 to 2018, and increase of the annual mean air temperature and amount of precipitation in natural zones of the region has been established on the basis of the analysis of linear trends. Under the impact of these factors, shifting of zone borders occurs, which leads to replacement of the soil cover structure at the species, generic and subtype levels. Changing regimes and soil properties cause the necessity to use new sorts and adapted technologies for crop growing.

“…The amount of accessible nutrients for trees increases with permafrost degradation, which causes an increase in their biomass [29]. An increase in the average annual temperature and rainfall contributes to the advancement of natural zones deep into the north, expanding the agricultural area and changing the structure of the soil cover with an increasing share of organic matter due to an increase in the productivity of vegetation [30].…”
