Gap regeneration in a broadleaved-Korean pine forest in Changbai Mountain Natural Reserve

Abstract

Abstract: Through comparing the quantitative characteristics of tree species composition in gap and non gap stands, this paper studied the response of main tree species to gap regeneration in the broadleaved-Korean pine forest in Changbai Mountain Natural Reserve, and expounded the role of gaps in maintaining the structure and diversity of the forest.With the alternation of gaps and non gaps in the broadleaved-Korean pine forest, the relative dominance of Korean pine vs.broadleaved trees, and of canopy layer trees vs.subcanopy and understorey layer trees changed alternatively.Gaps enhanced the species richness, increased the species diversity, made the coexistence of different species be possible, and thereby, maintained the stability of the whole broadleaved-Korean pine forest.

Key words: Broadleaved-Korean pine forest, Gap dynamics, Gap regeneration, Species diversity, phytoremediation, Miscanthus, energy plant, soil amelioration, heavy metal
