社会、经济和科学界对了解生物多样性在哪里、它是如何发展的以及可以做些什么来有效地减轻进一步的生物多样性损失和相关的生态系统服务损失的兴趣空前高涨。然而，迄今为止，生物多样性监测主要侧重于生态系统的结构和组成特征，尽管越来越多的证据表明，生态系统功能是阐明生物多样性为人类提供服务的机制的关键。这种监测差距可以追溯到目前缺乏共识的生态系统功能究竟是什么，以及如何跟踪他们在规模超过网站的水平。这一贡献的目的是推动全球生物多样性监测战略的制定，为此建议采用一套生态系统功能定义和类型，并审查卫星遥感技术支持监测全世界生态系统功能的现有机会和潜在限制。通过明确界定生态系统的过程，功能和服务及其相互关系，我们提供了一个框架，以改善生态学家，土地和海洋管理人员，遥感专家和决策者之间的沟通，从而解决该领域的一个主要障碍。
Societal, economic and scientific interests in knowing where biodiversity is, how it is faring and what can be done to efficiently mitigate further biodiversity loss and the associated loss of ecosystem services are at an all‐time high. So far, however, biodiversity monitoring has primarily focused on structural and compositional features of ecosystems despite growing evidence that ecosystem functions are key to elucidating the mechanisms through which biological diversity generates services to humanity. This monitoring gap can be traced to the current lack of consensus on what exactly ecosystem functions are and how to track them at scales beyond the site level. This contribution aims to advance the development of a global biodiversity monitoring strategy by proposing the adoption of a set of definitions and a typology for ecosystem functions, and reviewing current opportunities and potential limitations for satellite remote sensing technology to support the monitoring of ecosystem functions worldwide. By clearly defining ecosystem processes, functions and services and their interrelationships, we provide a framework to improve communication between ecologists, land and marine managers, remote sensing specialists and policy makers, thereby addressing a major barrier in the field.
