In recent years there has been an upsurge of studies on ecosystem multifunctionality (EMF), or the ability of ecosystems to simultaneously provide multiple functions and/or services. The concept of EMF itself, the analytical approaches used to calculate it, and its implications depending on the spatial scale and field of study have been discussed in detail. However, to date there has been little dialogue concerning the basis of EMF studies: what should or should not be considered appropriate measures for ecosystem functions.
To begin this discussion, we performed an in‐depth review of EMF studies across four major terrestrial ecosystems (agroecosystems, drylands, forests and grasslands) by analysing 82 studies, which together have assessed 775 ecosystem functions from a variety of field and greenhouse experiments across the globe.
The number of ecosystem functions analysed varied from two to 82 per study and we found large differences in the distribution of functions across ecosystem types and ecosystem service categories. Furthermore, there was little explanation of why certain variables were included in the EMF calculation or how they relate to ecosystem functioning.
Synthesis. Based on the literature analysis, it is clear that there is no general agreement regarding which measurements should or should not be considered functions in the field of ecology. To address this issue, we propose a general guideline for determining and measuring appropriate functions.

仔细研究生态系统多功能性背后的功能：回顾

近年来，对生态系统多功能性（EMF）或生态系统同时提供多种功能和/或服务的能力的研究激增。EMF本身的概念，用于计算EMF的分析方法及其取决于空间规模和研究领域的含义已得到详细讨论。但是，迄今为止，有关EMF研究基础的对话很少：什么应该或不应该被认为是生态系统功能的适当措施。
为了开始讨论，我们通过分析82项研究，对四个主要陆地生态系统（农业生态系统，旱地，森林和草原）的EMF研究进行了深入的回顾，这些研究共评估了775种生态系统的功能，这些功能来自整个田间和温室实验全球。
每个研究中分析的生态系统功能数量从两个到82个不等，我们发现跨生态系统类型和生态系统服务类别的功能分布存在很大差异。此外，几乎没有解释为什么某些变量包含在EMF计算中或它们与生态系统功能之间的关系。
综合。根据文献分析，很明显，关于在生态学领域中应该或不应该将哪些测量视为功能，尚无普遍共识。为了解决这个问题，我们提出了确定和衡量适当功能的一般指南。
