Features of the formation of agrophytocenosis flora structures in an anthropogenically transformed environment in the southwest of the Central Russian Upland

The article presents the results of studies of the flora of agrophytocenoses in the southwest of the Central Russian Upland, obtained in the period from 2017 to 2024. A critical analysis of the taxonomic, typological, ecological and geographical structures of the region's flora and the floras of agricultural crops and fallow lands included in it is carried out. The results indicate that the structures of agrophytocenoses' floras undergo significant changes under the influence of anthropogenic factors: the proportion of species of anemochorous families Chenopodiaceae and Polygonaceae of weeds and alien plants, herbaceous monocarpics, species of North American origin increases due to a decrease in the total number of species, representation in the flora of plants of the families Caryophyllaceae, Apiaceae and Ranunculaceae, herbaceous polycarpics, species of European origin. Specific features of the formation of the structure of floras in various types of agrophytocenoses have been established, which depend on the degree of anthropogenic impact on phytobiota.
