Abstrakt: The present paper studies the ruderal vegetation of the class Polygono-Poetea annuae in Kryvyi Rih. We present the ruderal plant communities of short annual species on the open, moist to dry ecotopes. Urban landscapes remain unstudied phytosociologically despite the highly diverse habitat niches. We have carried out the comparisons of communities from other regions of Ukraine and adjacent territories. In total, two associations and two variants, belonging to alliance were identified and categorized as follows Polygono-Coronopodion (the communities with the dominance of Polygonum aviculare). The ordination analysis indicates ecological differentiation of syntaxa investigated in Kryvyi Rih. The most important of them are soil water regime (Hd), variability of damping (fH) and soil aeration (Ae).
