摘要/Abstract

摘要： 通过对林隙及非林隙林分组成树种数量特征的对比分析,研究了长白山自然保护区阔叶红松林中主要树种对林隙的更新反应特点,阐述了林隙在阔叶红松林结构与多样性维持中的作用。随着林隙与非林隙的交替变化,红松和阔叶树以及主林层和中下层树种的相对优势(或重要性)亦呈现出交替变化的规律。林隙提高了阔叶红松林的物种丰富度,增加了其多样性,为不同特性物种的共存提供了可能,从而保持了阔叶红松林的整体稳定性。

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
