关于生态系统服务的研究在过去十年中迅速增长。已经公布了两个概念框架，以指导提供服务的生物体的生态评估--服务提供单位(SPU)和生态系统服务提供者(ESPS)的概念。在这里，我们统一了这些框架，并提出了SPU-ESP连续体，该连续体为综合生态系统服务研究的最新发展提供了一个连贯的概念方法，并可以指导未来各级组织的研究。特别是，我们展示了如何将服务提供者的概念应用于人口、功能群体和社区层面，我们强烈强调需要识别和量化提供服务的有机体及其特征(例如，功能特征)，并根据人类受益者的需求评估服务提供。我们使用文献中的关键例子来说明新的方法，并强调知识中的差距，特别是在物种相互作用和生态系统动态对服务提供的影响方面。
Research on ecosystem services has grown rapidly over the last decade. Two conceptual frameworks have been published to guide ecological assessments of organisms that deliver services-the concepts of service-providing units (SPUs) and ecosystem service providers (ESPs). Here, we unite these frameworks and present an SPU-ESP continuum that offers a coherent conceptual approach for synthesizing the latest developments in ecosystem service research, and can direct future studies at all levels of organization. In particular, we show how the service-provider concept call be applied tit the population, functional group, and community levels, We strongly emphasize the need to identify and quantify the organisms and their characteristics (e.g., functional traits) that provide services, and to assess service provision relative to the demands of human beneficiaries. We use key examples from the literature to illustrate the new approach and to highlight gaps in knowledge, particularly in relation to the impact of species interactions and ecosystem dynamics on service provision.
