摘要: 全球变化带来的土地利用和气候等因素的改变, 将对生产力、养分循环等生态系统功能产生重要的影响。以往研究大多只关注全球变化对单一功能的影响, 即使同时测定多种功能也是进行独立的分析。但由于不同功能间常常存在的权衡或协同关系, 导致基于单个功能的探讨难以反映全球变化对生态系统多功能性(ecosystem multifunctionality, EMF)的影响, 从而限制了人们对于全球变化影响的全面认识和评估。早在2007年, Hector和Bagchi首次量化EMF, 该领域才开始受到广泛关注。在此之后, EMF量化方法的不断完善, 极大推动了该领域的发展。近年来, 全球变化对EMF的影响也受到广泛的关注。为系统梳理该领域的研究进展, 该文基于中国知网、ISI Web of science等当前常用的学术期刊数据库, 检索2007–2020年的相关文献并进行计量分析, 系统归纳出该领域的发展现状。在此基础上, 详细阐述目前关注较多的土地利用变化、温度升高、降水改变以及氮沉降对EMF的影响, 并针对现有研究中存在的问题, 提出未来所需关注的6个方向: (1)规范EMF量化体系; (2)关注全球变化背景下多因子交互效应; (3)不同时间尺度下EMF对全球变化的响应; (4)全球变化背景下多维度、多尺度生物多样性与EMF; (5)全球变化背景下多营养级多样性与EMF; (6)全球变化背景下根系功能性状与EMF。

Abstract: Global change has exerted profound impacts on ecosystem functions, such as variations in plant productivity and imbalances in nutrient cycling. Previous studies were mostly focused on the impacts of global change on a single function. However, ecosystems can provide multiple functions simultaneously (namely, ecosystem multifunctionality, EMF), so the evaluation based on a single function is inappropriate to reflect the overall performance of ecosystem multiple functions, due to the trade-offs or synergies that often exist among different functions. And thus this will limit our understanding of the effects of global change on ecosystem functions. Since 2007, Hector and Bagchi have firstly quantified EMF, and then the improvement of EMF quantitative methods has greatly promoted the development of this field. As global change intensified, the impact of global change on EMF has received widespread attention in the recent years. In order to systematically understand the research progress in this field, this paper is performed to conduct a bibliometric analysis from 2007 to 2020 based on the two common literature databases, including CNKI and ISI Web of Science. We briefly described the development of this field, and summarized the impacts of land use change, warming, precipitation change and nitrogen deposition on EMF. Finally, we proposed six directions that require to be noticed in further studies under the scenario of global changes: (1) Make consensus in EMF indices and evaluation method; (2) Consideration on the interactive effects among different factors on EMF; (3) Response of EMF to global changes across various temporal scales; (4) Relationships between multi-dimensional, multi-scale biodiversity and EMF; (5) Relationships between multidiversity and EMF; (6) Relationships between root functional traits and EMF.
