摘要
全球变化与生态系统研究是一个宏观与微观相互交叉、多学科相互渗透的前沿科学领域,重点研究生态系统结构和功能对全球变化的响应及反馈作用,其目标是实现人类对生态系统服务的可持续利用。《植物生态学报》的《全球变化与生态系统》专辑在对国内外全球变化研究进行历史回顾和综合分析的基础上,总结了全球变化与生态系统研究的阶段性重大进展及存在的主要问题,并对全球变化研究的前沿方向进行展望和建议。根据研究内容和对象,该专辑系统地综述了不同全球变化因子,包括CO2和O3浓度升高、气候变暖、降水格局改变、氮沉降增加、土地利用变化等对陆地植物生理生态、群落结构及生态系统功能等的影响以及全球变化对海洋生态系统的影响;探讨生态系统关键过程以及生物多样性的变化;在明确全球变化生态效应的基础上,阐明这些影响对气候和环境变化的反馈机制,为构筑全球变化的适应对策提供生态学理论基础。
The response and feedback of ecosystems to global change is a scientific frontier in ecosystem ecology,which combines macro-and micro-level studies across multidisciplines.It focuses on the responses of ecosystem structure and function to global change,and its objective is to achieve sustainable use of ecosystem services.Based on the review of previous studies,we summarized the major progress and main achievements in this field and made an outlook for future challenges.According to the research content and object,this special issue systematically reviewed the effects of different global change factors,including increasing atmospheric CO2 and O3 concentration,global warming,precipitation change,increasing nitrogen deposition and land use change,on terrestrial plant ecophysiology,community structure,and ecosystem functions,and global change impacts on marine ecosystems.It mainly discussed the changes in biogeochemical cycles and biodiversity under global change,and clarified the mechanisms underlying feedback between ecosystem and climate change.The study of this research area could provide theoretical basis for the construction of global change adaptation strategies.
