Using the method of synphytoindication, the sizes of ecological factors, which characterize the ecotopes of xerothermic vegetation, widespread within the limits of the Transcarpathian Lowland, were calculated. The basic factors, which determine differentiation of heterospecific extrazonal vegetation are a group of edaphic factors: mode of soil moistening and content of calcium compositions in it, in less measure the acidity of soil. The obtained results show that distribution of xerothermicvegetation on the Transcarpathian Lowland also closely correlates with the sizes of climatic (generalized temperature mode and climate’s frost mode) environmental factors, which are important for the investigated region. Due to studying the ecological extends’ positions of the investigated areas in relation to the parameters of environment an ordinational analysis was applied. Maximum differences because of the most factors are characterize habitats of Chorna Mountain and Chernecha mountain. The most amplitudes of ecological factors and ecological extends are peculiar to Lovachka mountain.
