基于生态位理论的森林树种多样性保护与利用
摘 要
随着全球生态环境问题的日益严峻，森林生态系统作为地球上最重要的生态系统之一，其保护与可持续利用问题备受关注。森林树种多样性作为森林生态系统的重要组成部分，对维持生态系统稳定性、促进生物多样性和提升森林服务功能具有重要作用。本研究基于生态位理论，对森林树种多样性的保护与利用进行了深入探讨。首先，阐述了生态位理论的核心概念与内涵，以及森林树种多样性的生态位特征。在此基础上，提出了基于生态位理论的森林树种多样性保护策略，包括关键树种的生态位识别与保护优先序确定、森林群落结构的生态位优化配置以及生境异质性与树种多样性的协同保护。同时，本研究还探讨了生态位理论指导下的森林树种资源可持续利用，包括树种资源利用的生态位适宜性评价、多功能森林经营中的生态位调控技术以及基于生态位的森林生态系统服务功能提升。

CONSERVATION AND UTILIZATION OF FOREST TREE SPECIES DIVERSITY BASED ON ECOLOGICAL NICHE THEORY
ABSTRACT
With the increasingly severe global ecological and environmental problems, as one of the most important ecosystems on the earth, the protection and sustainable utilization of forest ecosystem have attracted much attention. As an important part of forest ecosystem, forest tree species diversity plays an important role in maintaining ecosystem stability, promoting biodiversity and improving forest service function. Based on the conservation and utilization of forest tree diversity. First, the core concepts and connotations of niche theory as well as the niche characteristics of the diversity of forest tree species. Furthermore, niche theory-based forest tree species diversity conservation strategies are proposed, including niche identification and conservation prioritization of key tree species, optimal niche allocation of forest community structure, and coordinated conservation of habitat heterogeneity and tree species diversity. At the same time, this study also discusses the sustainable utilization of forest tree species resources under the guidance of ecological niche theory, including the ecological niche suitability evaluation of tree species resource utilization, the ecological niche regulation technology in multi-functional forest management, and the improvement of forest ecosystem service function based on ecological niche.
