摘要
次生林是天然林采伐后形成的主要森林类型,在林分结构与物种组成、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,研究次生林生态系统健康诊断、类型分类与评价指标,群落结构与生态功能以及土壤生态过程等,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,探讨了次生林诊断、类型分类与评价方法,群落结构与生态功能,以及森林恢复过程对次生林的影响等,阐明次生林研究中所关注的基础科学问题,并提出了次生林未来研究方向,为我国次生林多目标经营、生态系统管理和天然林保护与修复等提供科学依据。
The secondary forest is the main forest type formed after natural forest cutting,which is significantly different from the primary forest and artificial forest in many aspects,such as stand structure and species composition,forest growth and productivity,stand environment and ecological functions,etc.Therefore,studying the health diagnosis,classification and evaluation index,community structure and ecological functions,and soil ecological processes of the secondary forest ecosystem are of great significance for biodiversity protection,ecological security,ecological barrier construction and ecological civilization construction in China.Based on the extensive collection of the latest literature on secondary forest research at home and abroad,this paper discussed the diagnosis,classification and evaluation method of secondary forest,community structure and ecological function,as well as the impact of forest restoration process on secondary forest,etc.At the same time,this paper explained the basic scientific issues concerned in the research of secondary forests,and proposed future research directions for the secondary forest,which would provide scientific basis for the multi-purpose management of secondary forest,ecosystem management,and natural forest protection and restoration in China.
