The paths of migration of charcoal particles in the post-pyrogenic soils of the taiga and tundra depending on features of fire and environmental factors
The work is devoted to the analysis of the regularities of the movement of charcoal particles in the ecosystems of the middle taiga, northern taiga and southern tundra experiencing the influence of fires. Since coniferous vegetation is subjected to intense combustion, fires often lead to cyclical ch...

The work is devoted to the analysis of the regularities of the movement of charcoal particles in the ecosystems of the middle taiga, northern taiga and southern tundra experiencing the influence of fires. Since coniferous vegetation is subjected to intense combustion, fires often lead to cyclical changes in the vegetation cover. The process of burning leads to the forest litter damage, making the soil cover vulnerable to erosion. Intense fires affect the amount of pyrogenic material that can be stored for thousands of years under favorable conditions. The aim of the research was to estimate the influence of environmental factors on the use of carbonaceous particles in modern time series (from 1 to 119 years). The features of soils (particle size distribution, moisture content), relief features (presence of depressions), the effect of precipitation material after a fire, as well as features of combustible litter were considered.
