ABSTRACT: The study of
phytocenoses of transitional environmental conditions in the Pre-Baikal Region
enabled to reveal modern tendencies of vegetation development in different
Pre-Baikal sites. Such cenoses can serve as a regional model for indication of
existing processes and of changes in vegetation structure which occurred under
different environmental conditions. It is found out that ecotones and cenoses reflecting the paragenese in
vegetation structure indicate structural-dynamic
peculiarities of the organization of Pre-Baikalian vegetation cover as a whole.
They are valid for classification and characterize intrazonal differences in
vegetation structure at vaste territories. Ecotones and paragenese in the
vegetation structure in the studied area reflect physical and geographical
conditions of their formation for a definite time period.
