摘要: 物种的空前丧失促使人们越来越多地开始研究物种多样性与生态系统功能的关系,并探讨其潜在的作用机制。本文根据最新研究进展,归纳了微宇宙实验、“生态箱”实验、Cedar Creek草地多样性实验和欧洲草地实验等代表性实验中关于物种多样性与生产力、稳定性、抗入侵性等生态系统功能的焦点问题,介绍了去除实验在多样性与生态系统功能研究中的应用。在此基础上,提出未来研究所面临的挑战,并对研究趋势进行了展望。主要挑战和趋势有:将小尺度上开展的实验研究扩展到较大的时空尺度上;综合考虑生物因素和非生物因素对多样性变化、生态系统功能的交互作用;营养级之间的相互作用、物种共存机制对物种多样性与生态系统功能关系的影响。

Abstract: The unprecedented loss of species has motivated people to conduct considerable researches to describe the relationships between species diversity and ecosystem functioning and to reveal the mechanisms underlying. Based on the recent advances, some key issues on the relationships between species diversity and ecosystem functioning (such as productivity, stability, and invasion-resistance) in several representative experimental studies, including microcosm, Ecotron, Cedar Creek grassland experiment, and European BIODEPTH, as well as the applications of removal experiment in the studies of species diversity and ecosystem functioning, were summarized, and, based on the current understanding of the relationships between species diversity and ecosystem functioning, future challenges and trends were prospected, including the extension of experimental results from small temporal and spatial scales to larger temporal and spatial scales, the comprehensive consideration on the interactions of biotic and abiotic factors on species diversity and ecosystem functioning, and the effects of trophic levels and species coexistence mechanisms on the relationships between species diversity and ecosystem functioning.
