人为干扰对中国次生林的影响:I. 林木生长、更新与群落结构

Effects of Human Disturbance on Natural Secondary Forests in China: I. Tree Growth, Regeneration and Community Structure

  • 摘要: 天然次生林是天然林采伐后形成的主要森林类型,在林分物种组成与结构、林木生长与生产力、林分环境与生态功能等诸多方面与原始林和人工林有着显著差异。因此,研究人为干扰对次生林群落物种组成、林木生长、更新以及群落结构等的影响,对我国生物多样性保护、生态安全、生态屏障构建和生态文明建设等具有重要意义。本文在广泛收集整理国内外有关次生林研究最新文献基础上,探讨人为干扰对天然次生林群落林木生长、物种组成、群落结构等的影响,阐明人为干扰在改善和提升天然次生林质量的积极作用,并提出了人为干扰对天然次生林演替进程影响的未来研究方向,为我国天然次生林保护与修复、生态系统管理与多目标经营等提供科学依据。

     

    Abstract: Natural secondary forest is the main forest type formed after natural forest harvesting, which is significantly different from primary forest and artificial forest in many aspects, such as species composition and structure, forest growth and productivity, stand environment and ecological function. Therefore, it is of great significance for biodiversity protection, ecological security, ecological barrier construction and ecological civilization construction in China to study the effects of human disturbance on species composition, tree growth, regeneration and community structure of secondary forest community. On the basis of extensive collection of the latest literature on secondary forest research at home and abroad, the impact of human disturbance on forest growth, species composition and community structure of natural secondary forest were discussed, and the positive role of human disturbance in improving the quality of natural secondary forest were expounded. In the end, the future research direction of the influence of human disturbance on the succession process of natural secondary was put forward, providing scientific basis for the protection and restoration of natural secondary forest, ecosystem management and multi-objective management in China.
