摘要: 应用Simpson和Shannon多样性指数及其相应的均匀度,对阔叶红松林及其次生白桦林的高等植物物种多样性进行了对比研究。结果表明,对于木本植物,次生白桦林物种多样性高于阔叶红松林;而对于草本植物,情况正好相反。但在次生白桦林中,无论木本植物还是草本植物,占优势的物种都是一些常见种,而许多阔叶红松林中的珍稀或特有物种在次生白桦林中数量很少,有些甚至完全消失。对群落各种群多度分布的检验表明,2种森林类型中,无论木本植物还是草本植物,各种群的多度分布都遵从对数级数分布。

Abstract: Simpson and Shannon diversity indices and their eveness are used to analyse the difference of diversity of higher plants in broad-leaved Korean pine forest and secondary birch forests.The results show that the species diversity of higher plahts in secondary birch forest is higher than that in broad-leaved Korean pine forest for woody plants, but for herbs,the latter is higher.Many of rare species existed in broad--leaved Korean pine forest are few or absent in secondary birch forest.Species abundance distributions of both woody plants and herbs in these two forests obey a logarithmic series distribution.

Key words: Species diversity, Broad-leaved Korean forest, Birch forest, Species abundance distribution
