摘要:

全球变化和人类活动正以空前的速度在世界范围内改变着生物多样性, 这导致了全球生物多样性的锐减以及生产力的下降、病虫害的增加和抗入侵能力的减弱等生态问题。近30年来, 生态学家开始对于生物多样性的持续丧失是否以及如何影响生态系统功能的问题越来越感兴趣, 生物多样性与生态系统功能(biodiversity and ecosystem functioning, BEF)关系的研究应运而生, 并成为生态学研究的热点之一。但长期以来, 研究者更多地关注单一生态系统功能, 而忽略了生态系统能够同时提供多种生态系统功能的能力, 即生态系统多功能性(ecosystem multifunctionality, EMF)。本文综述了EMF研究中功能指标的选择、生物多样性的不同维度、微生物多样性对EMF的影响以及其他非生物因子对EMF的驱动等进展。因只考虑单一功能可能会低估生物多样性对整体生态系统功能的影响, 故生物多样性与生态系统多功能性(BEMF)关系的研究成为BEF关系研究的重点。近年来, BEMF关系的研究发展较快, 在不同生态系统(包括水生、草地、森林、旱地、农业等)、不同研究尺度(从区域到全球尺度)、BEMF关系的驱动机制(从单一驱动机制到多种驱动机制共同作用)、研究方法(包括新概念以及新的量化方法的提出和应用)等方面均取得了新的进展。但仍有不足之处, 如对于EMF研究中功能指标的选取没有统一的标准、对地下微生物多样性的关注度不够、涉及多营养级水平下的BEMF关系研究较少、驱动EMF的机制仍存在争论等。未来应加强对于功能指标选取的标准研究, 综合分析地上、地下生物多样性以及非生物因子对EMF的整体影响, 加强生态系统多服务性(ecosystem multiserviceability, EMS)方法的研究和应用。

Abstract

Background & Aims: Global change and other human activities are changing biodiversity around the world at an unprecedented rate, which has led to a sharp decline in global biodiversity and productivity, an increase in pests and diseases, and a weakening of the ability to resist invasion and other ecological problems. Ecologists became more and more interested in the question of whether and how the continuous loss of biodiversity would affect ecosystem functioning in the last 30 years. Therefore, the relationship between biodiversity and ecosystem functioning (BEF) became one of the hot topics of ecological research. For a long time, researchers have focused more on individual ecosystem functions than on the ability of an ecosystem to provide multiple ecosystem functions at the same time, known as ecosystem multifunctionality (EMF). Considering only individual functions could underestimate the impact of biodiversity on overall ecosystem functioning. Therefore, the relationship between biodiversity and ecosystem multifunctionality (BEMF) has become the focus of BEF research field. In order to enrich the understanding of BEMF relationships, this paper focuses on different dimensions of biodiversity and the impact of microbial diversity on EMF, how abiotic factors drive EMF, as well as the selection of functional indicators in the evaluation of EMF.
Progresses: In recent years, the research on BEMF relationships has developed rapidly, expanding from aquatic ecosystems to grasslands, forests, drylands and agricultural ecosystems. Spatial scale ranges from regional scale to global scale. The driving mechanisms of BEMF relationship are explored from single dominant driving mechanism to multiple driving mechanisms. There are also new innovations in research methods and new concepts put forward.
Prospects: However, there are still some shortcomings. For example, there is no unified standard for the selection of functional indicators in EMF research, insufficient attention to microbial diversity, few studies on the BEMF relationship at the multitrophic level, and debate about the mechanisms driving EMF. In the future, it is necessary to strengthen the research on the criteria for the selection of functional indicators, comprehensively analyze the overall impact of aboveground and belowground biodiversity and abiotic factors on EMF, and strengthen the research and application of ecosystem multiserviceability (EMS).
