摘要:

生物多样性与生态系统功能的关系(BEF)及其内在机制是当前生物多样性研究领域的热点问题。长期以来,以草地生态系统为主的BEF研究积累了大量研究成果,而基于森林生态系统的相关研究则相对较少。亚热带森林生物多样性与生态系统功能实验研究基地(BEF-China)是目前包含树种最多、涉及多样性水平最高的大型森林控制实验样地。该文总结了基于BEF-China平台的研究进展,特别是生物多样性对生态系统生产力、养分循环以及多营养级相互作用关系等方面的影响,并提出了未来BEF-China的研究应注重高通量测序和遥感等新兴技术的应用,在生物多样性的多维度、生态系统的多种组分与多种功能以及BEF研究的多种尺度等交叉方向上持续开展深入研究。针对BEF-China研究成果的梳理有助于理解驱动亚热带森林生物多样性与生态系统功能关系的内在机理,为生物多样性保护和生态修复提供科学依据。

Abstract:

The relationship between biodiversity and ecosystem functioning(BEF)and the underlying mechanisms have been a hot issue in ecological research. Whereas many BEF studies have focused on grassland ecosystems, relatively few have been conducted in forest ecosystems which account for a large proportion of primary production in the terrestrial ecosystem. Biodiversity-Ecosystem Functioning Experiment China Platform(BEF-China)contains the most tree species with the highest level of diversity in subtropical forests. In this review, we first summarized research progress in BEF-China, and then gave suggestions for future BEF research. The research based on BEF-China mainly focused on the impact of biodiversity on multi-ecosystem functioning, e.g. productivity, nutrient cycling and multi-trophic interaction. We suggest that future studies in BEF-China should strengthen the application of new techniques such as high-throughout sequencing and remote sensing, and continue research on multi-dimensions, multi-components, multi-ecosystem functions, and multi-scales in BEF study. The research progress of BEF-China can help in better understanding the BEF relationships in forest ecosystem, and provide a scientific support for biodiversity conservation and ecological restoration.
