Abstract
As a result of quantitative «microecosystem» analysis of structural and functional relationships between biogeocenosis components in coniferous forests, the leading role of stand-edificator's root competition factor has been identified in determining the undergrowth and lower layer plant’s growth, compared with its «light» competition. Considering the dominant role of a tree stand root competition in the formation of other forest biogeocenosis components, new definition of «forest» as «underground-closed dendrocenoecosystem» have been proposed.
