Formation of Forests under Contrast Environmental Conditions in South-Western Pre-Baikal, South-Western Trans-Baikal and North-East Pre-Baikal (Some Aspects of Structure and Dynamics)

摘要

Zonal and height belts differentiation of environmental parameters determine forms and types of changes during formation of systems of any natural hierarchy. Under climatic conditions, when shifts of environmen tal (geographic) zones or height belts as definite environments is possible, there are processes able to result in structural differentiation of the whole biosphere. The problem of forests and steppes interaction is up to nowadays a subject of essential studies of the peculiarities of cenoses formation under transitional environmental conditions in different areas and territories.
