Sharafutdinova Maulikha Sabirovna  ( graduate student, Tobolsk Pedagogical Institute Mendeleyev, a branch of the Tyumen State University, Tyumen region)

Phytocenosis with the participation of Tilia cordata Mill. in their distribution area in the three regions of the south of the Tyumen region studies have narrow and similar spectra of environmental factors. The more significant indicators of the realized ecological valence on four ecological scales are noted: nitrogen richness of soil, acidity, on continental climate, and also on the factor of illumination. Realized ecological valencies of the populations of Tilia cordata Mill. in the studied lime trees is much lower than the potential, its value varies from 0,11 to 024.

Keywords:Realized ecological valence, potential ecological valence, coefficient of ecological efficiency.
