南岭山地天然林受损现状及生态恢复研究进展OA
Research progress on the damage status and ecological restoration of natural forests in the Nanling mountains
南岭山地是国家生态安全屏障的重要组成部分,其生态系统在人类活动与自然干扰的双重胁迫下日趋脆弱,生物多样性丧失与生态风险问题突出.因此,亟待发展针对受损生态系统恢复与生态安全的保障技术,以服务于区域可持续发展.鉴于此,本文通过综述南岭山地天然林受损的现状及生态恢复技术相关研究进展,为受损森林生态系统恢复与可持续发展提供科学依据,从而服务于我国天然林保护修复及生态安全保障技术的研发和应用.在全球气候变化背景下,本文通过系统梳理国内外相关文献,综合分析南岭山地天然林退化的驱动因素、恢复技术及实践效果.结果表明,自然干扰(如冰雪灾害等)是导致南岭山地天然林林分结构破坏和逆向演替的主因,而人为干扰(如竹类扩张等)则进一步加剧生物多样性的丧失与土壤退化.在受损天然林生态系统功能与稳定性提升技术研发过程中发现,加强萌蘖管理、近自然混交经营及智能决策支持系统可显著提升恢复技术应用效率.同时,分类经营与碳汇功能协同模式对蓄积量增长和生态功能恢复具有积极作用.综上,研究结果为南岭山地受损天然林的科学恢复提供了技术支撑,对保障南岭山地生态屏障功能持续提升具有重要理论与实践价值.
The Nanling mountain region is a critical component of China's ecological security barrier.Its ecosystems are becoming increasingly fragile due to the dual pressures of human activities and natural disturbances,leading to prominent issues such as biodiversity loss and elevated ecological risks.So,there is an urgent need to develop restoration and security assurance technologies for degraded ecosystems to support regional sustainable development.Accordingly,this paper aims to review the current degradation status of natural forests and the research progress on ecological restoration technologies in the Nanling mountain region,thereby providing a scientific basis for forest ecosystem restoration and sustainable development.It is expected to promote the research and application of natural forest protection and ecological security technologies.Under the context of global climate change,this study systematically synthesizes relevant domestic and international literature to comprehensively analyze the driving factors of natural forest degradation,restoration technologies,and their practical effectiveness in the Nanling mountain region.The results indicate that natural disturbances such as ice-snow disasters are the primary causes leading to the destruction of stand structure and regressive succession of natural forests in the Nanling mountains,while anthropogenic disturbances such as bamboo expansion further exacerbate biodiversity loss and soil degradation.In the research and development of technologies for enhancing the functions and stability of degraded natural forest ecosystems,strengthening sprout management,close-to-nature mixed silviculture and intelligent decision-support systems can significantly enhance the efficiency of restoration technology application.Meanwhile,the synergistic model of classified management and carbon sink function plays a positive role in the increase of stand volume and the restoration of ecological functions.In summary,the findings provide technical support for the scientific restoration of degraded natural forests in the Nanling mountains,and have important theoretical and practical value for ensuring the continuous improvement of the ecological barrier function of the Nanling mountains.
