Interest in ecosystem services accounting is growing exponentially. There are many un-solved issues that need to be addressed, the notion of capacity is among them. International guidelines suggest that capacity should constitute the link between the ecosystem assets accounts and the ecosystem services accounts. In order to address this issue, the authors use Supply and Use table for ecosystem services to show the relationship between (i) ecosystem assets and (ii) capacity, intended as "virtual stock" of individual ecosystem services. It is in fact important to distinguish ecosystem assets from capacity as "virtual stock": a comparison between asset accounts for natural resources and capacity is presented to clarify this difference. This novel approach is described together with its implications in order to feed further developments and discussion.
对生态系统服务核算的兴趣正呈指数级增长。有许多未解决的问题需要加以解决，能力的概念便是其中之一。国际准则建议，能力应构成生态系统资产账户与生态系统服务账户之间的联系。为解决这一问题，作者使用生态系统服务的供给与使用表来展示（i）生态系统资产与（ii）能力之间的关系，能力被视为单个生态系统服务的“虚拟存量”。实际上，将生态系统资产与作为“虚拟存量”的能力区分开来很重要：文中呈现了自然资源资产账户与能力之间的比较，以阐明这种差异。本文描述了这种新颖的方法及其影响，以便推动进一步的发展和讨论。
