ABSTRACT: The published paper presents the results characterizing structural-dynamical
changes and anthropogenic destructions of forests, which form in the zones of contact
between taiga and extrazonal steppe of Barguzin and Tunka Depressions (the Baikal
Region). We have used perennial (for 22 years) geobotanical descriptions of model
sites and made inventory large-scale geobotanical schematic maps on the base of
field deciphering of aerophotographs of different years (1974-2002). Soil-geobotanical
profiling allowed revealing some links of edaphic conditions with structural-dynamical
characteristics of forest cenoses of the above-mentioned areas of Pre-Baikal. The
subject of studies is determination of the trends of forest cenoses development in the zones of contact between forest and extrazonal steppe.
Such cenoses reflect structurally and dynamically changes occurring in natural zones
on the background of climatic fluctuations
under anthropogenic impact much more rapidly than zonal vegetation.
