Using synphytoindicative method the magnitude of ecological factors which characterizes habitats of xerothermic vegetation within Podillia elevation and Transcarpathian lowland was calculated. The results indicate that the distribution of xerothermic meadow-steppe and steppe formations on the examined area is closely correlated with climatic variables (generalized thermal regime, continentality, humidity and climate frigidity) and some edaphic factors (salt regime and the content of mineral nitrogen) of environment, the averages of which are almost the same for Podillia and Transcarpathia. It can be stated with sufficient probability that the division of Eastern European provinces into the Balkan-mezian (Prydunays’ka) and East European steppe is based on values’ distinctionsof edaphic factors – soil moisture, calcium content in it and soil acidity.
