- Аннотация: Abstract—This article is devoted to the assessment of the effect of biotic, abiotic, and anthropogenic factorson the dynamics of production processes of various ecosystems located in the same natural and climatic subzone: the southern taiga of the Eastern European Plain. The study was performed on four test plots in Vladimir oblast located in various landscape provinces with similar climatic conditions, but differed in some features of the soil and plant cover, anthropogenic load, andland-use pattern. The calculation of productivity parameters in carbon units was based on MODISGPP/NPP data. Organic carbon reserves in soil were determined according to the Food and AgricultureOrganization (FAO) of the United Nations based on plugin Trends.Earth of QGIS. The dynamics of parameters of vegetation productivity from year to year on the background of its absolutevalues is common for the four ecosystems. Conditions for carbon accumulation in soil are favorable in areaswith high productivity and a large number of overgrown lands. The results of the ANOVA analysis of varianceshow that the factors of time and spatial position of test plots do not affect the content of organic carbon insoil, or the gross biological productivity. The land-use pattern is a significant factor. It is shown that insufficient productivity of some ecosystems is compensated by an increased productivity of neighboring ones;therefore, the preservation of intralandscape diversity is a necessary condition for maintaining the stability oftheir functioning.
