Abstract:

Permanent sample plots were set up in windfall area in western slope of Changbai mountain to investigate regeneration successively and determine changes in ecological habitats. The results indicate that the composition of regeneration population is a mixture of shade-tolerant and intolerant tree species. Abundance of shade-tolerant trees tends to decrease and that of intolerant trees increases year by year. Contents of soil water, C, N and organic material in windfall plots decrease. Tendings of forest promote the restoration of habitats.

Key words: Korean pine broadleaf mixed forest, Windfall area, Population regeneration, Habitat restoration
