Abstract

The article presents data on climate change in the Trans-Ural steppe zone of the Republic of Bashkortostan over the past 23 years, during which there has been an increase in water reserves in snow by 3.8%, precipitation by 18.9% and temperature by 30% (during the snowmelt period); an increase in the number of days with dust storms by 15% in the presence of 44% deflationary-dangerous winds, as well as a decrease during the growing season in the amount of precipitation by 19.2% and an increase in the average air temperature by 6.2%, as well as the sum of positive temperatures for the year by 5.2%. These factors increase the risks of soil erosion and salinization processes in the Trans-Ural steppe, during the development of which the thickness of humus-accumulative horizons, the content and reserves of organic matter decrease, and its quality changes.
