Abstract

Abstract:

Based on the niche ecostate-ecorole theory proposed by Chunquan Zhu, we improved the model of regeneration niche, regarding the niche of the arbor tree and the sapling as the ecostate and the ecorole of the regeneration niche. Through the investigation on the gap regeneration of the Changbai mountains Korean Pine broad-leaved mixed forest, the quantitative characteristics of regenerated tree species in the gaps were analyzed, and the breadth and the overlap of the regeneration niche were calculated in this paper. The result showed that the improved model did not only ensure the mathematics logistic coherence, but also increase the ecological explain meaning, and advance the precision of the regeneration niche metrics.

Key words: gap, regeneration niche, Korean Pine broad-leaved mixed forest, Changbai Mountains
