摘要
全球气候变化导致的干旱对森林生态系统结构和功能的影响已成为学术界和环境保护领域的关注焦点。文中通过综合分析现有研究文献,总结了全球气候变化下干旱对森林生态系统结构与功能的影响。目前的研究发现,干旱能够引起森林生物地球化学循环减弱、森林火灾频率增加、物种组成和生物多样性损失、森林抵抗力和恢复力减弱以及森林生产力和稳定性下降等现象。对此,需要通过长期观测、延长控制实验时间、模拟原生环境条件等开展多因素综合实验,进一步探究地上—地下耦合过程对干旱的反馈调节机制以及森林植被对于干旱胁迫的生物调节机制,为进一步理解干旱对森林生态系统的影响以及制定干旱条件下森林经营管理对策提供理论参考。
The impacts of drought on the structure and function of forest ecosystems under the global climate change have become the hot issue in the academic community and in the field of environmental protection.In this paper,the impacts of drought on forest ecosystem structure and function under global climate change are summarized through the comprehensive literature review.Current studies have found that drought causes the decrease of forest biogeochemical cycle,the increase of forest fire frequency,the loss of species composition and biodiversity,the decline of forest resistance and resilience,and the decline of forest productivity and stability.It is necessary to conduct comprehensive multi-factor experiments through long-term observation,extension of controlled experiment time,simulation of primary environmental conditions,etc.,to further explore the feedback regulation mechanism of above-ground coupling process on drought and the biological regulation mechanism of forest vegetation on drought stress.It would provide a theoretical reference for further understanding the impacts of drought on forest ecosystem and developing countermeasures for improving forest management under drought conditions.
