The dynamics of the morphology and chemical properties of forest litter during natural post-agrogenic reforestation and its reflection on the ground cover
Abstract
The features of the dynamics of the morphology and chemical properties of forest litter during post-agrogenic reforestation of arable land in the southern taiga subzone are studied. The relationship between the dynamics of the structure of litter with the floristic composition and the ecological-coenotic structure of the soil cover is shown. The increase in stocks, as well as the diversity of the structure and the degree of spatial variation of the main morphological indicators of litter as the regeneration of the stand has been established. Acidification and a decrease in the ash content of litter, as well as a decrease in the fraction of easily decomposed fractions, are adequately reflected in the composition of the soil cover, in which the role of species adapted for increased acidity and low content of nutrients in the substrate increases. After spruce enters the first tier, the spatial distribution of the structure, reserves, power, and fractional composition of litter is determined by the position in the tesser. In general, the course of succession, as well as the dynamics of the morphology and chemical properties of litter, indicates a decrease in the rate of circulation in biogeocenosis. The ecological scales of Ellenberg, Landolt, Tsyganov and Ramensky as applied to ground cover can serve as an important tool in analyzing the dynamics of forest litter in forest ecosystems.
