Distribution patterns of main tree species in Tilia broadleaf Korean pine forest on northern slope of Changbai Mountains

Abstract

Abstract: In this paper,variance/mean test,χ² test of Poisson distribution and χ² test of negative binomial distribution are used simultaneously to detect the distribution patterns of main tree species in Tilia broadleaf Korean pine forest sampled by two methods, and the results are tested by location drawing with sample size of 1 hm². The results show that sampling with a size of 5 m×5 m is fit for arboreous trees. Pinus koraiensis,Tilia amurensis,Fraxinus mandshurica,Maackia amurensis and Acer mandshurica belong to an aggregate distribution,and Quercus mongolica and Ulmus propinqua to a stochastic one.

Key words: Tilia broadleaf Korean pine forest, Distribution pattern, Community, distribution pattern, resource restoration, species composition, fish eggs, fish larvae, artificial reefs
