Abstract
The syntaxonomical diversity of the ruderal vegetation of the class Artemisietea vulgaris in the territory of Ukraine has been studied in 2015-2020. It is established that this class includes 58 associations from six alliances (Convolvulo arvensis Agropyrion repentis, Arction lappae, DaucoMelilotion, Onopordion acanthii, Medicagini falcataeDiplotaxion tenuifoliae and Rorippo austriacaeFalcarion vulgaris) and two orders (Agropyretalia intermediorepentis and Onopordetalia acanthii). Based on the results of the DCA-ordination analysis, it was found that the distribution of this type of ruderal vegetation is determined by the concentration of mineral nitrogen, the degree of aeration of the substrate, and the variability of moisture. At the level of highrank syntaxa we didn’t find only vegetation that was specific for subMediterranean and Mediterranean regions as well as for eastern part of European russia. At the same time, we determined specific vegetation on the European scale from the territory of Ukraine. This is Crimean submediterranean xero-mesophytic ruderal vegetation and semiruderal meso-xerophytic vegetation united into two alliances – Medicagini falcataeDiplotaxion tenuifoliae and Rorippo austriacaeFalcarion vulgaris. All associations within these alliances are also specific only for the territory of Crimea, characterized by the specific floristic structure and diagnostic species core, and didn’t find in other regions of Ukraine.
