Comparative analysis of systematic and typologic structure of floras with different transformation extent has been conducted: the analysis of Kazenny Torets river basin flora, pasrures flora and mine rock dumps flora. The increase of anthropogenic impact starting from flora of Kazennyi Torets river basin through steppe pastures flora to mine dumps flora is accompanied by progressive decrease of specific diversity, by the change of systematic structure, the decrease of structural elements and by replacement of species adapted to certain factors by synanthropic and adventitious species adapted to certain anthropgenic inpact. The procecces of floras adaptation to anthropogenic impact have been investigated at the level of structural elements. The basic tendencies of floras structure variation have been revealed.
