Signatory countries to the Convention on Biological Diversity (CBD) are formulating goals and indicators through 2050 under the post-2020 Global Biodiversity Framework (GBF). Among the goals is increasing the integrity of ecosystems. The CBD is now seeking input toward a quantifiable definition of integrity and methods to track it globally. Here, we offer a schema for using Earth observations (EO) to monitor and evaluate global forest ecosystem integrity (EI). Our approach builds on three topics: the concept of EI, the use of satellite-based EO, and the use of “essential biodiversity variables” to monitor and report on it. Within this schema, EI is a measure of the structure, function, and composition of an ecosystem relative to the range of variation determined by climatic–geophysical environment. We use evaluation criteria to recommend eight potential indicators of EI that can be monitored around the globe using Earth Observations to support the efforts of nations to monitor and report progress to implement the post-2020 GBF. If operationalized, this schema should help Parties to the CBD take action and report progress on achieving ecosystem commitments during this decade.

在 2020 年后全球生物多样性框架内监测森林生态系统完整性

《生物多样性公约》（CBD）的签署国正在根据 2020 年后全球生物多样性框架（GBF）制定到 2050 年的目标和指标。目标之一是提高生态系统的完整性。CBD 现在正在寻求对完整性的可量化定义和方法的输入，以在全球范围内对其进行跟踪。在这里，我们提供了使用地球观测 (EO) 监测和评估全球森林生态系统完整性 (EI) 的模式。我们的方法建立在三个主题之上：EI 的概念、基于卫星的 EO 的使用以及使用“基本生物多样性变量”对其进行监测和报告。在该模式中，EI 是相对于由气候-地球物理环境确定的变化范围的生态系统结构、功能和组成的度量。我们使用评估标准推荐八个潜在的 EI 指标，这些指标可以使用地球观测在全球范围内进行监测，以支持各国监测和报告 2020 年后 GBF 实施进展的努力。如果实施，该模式将帮助 CBD 缔约方采取行动并报告在这十年内实现生态系统承诺的进展。
