简要介绍了千年生态系统评估(MA)项目亚全球评估工作组的报告《生态系统与人类福祉:多尺度评估》的核心内容,重点在于多尺度评估的贡献以及从中获取的经验教训。多尺度评估的贡献主要表现在:① 全面、系统地阐述了生态系统服务与人类福祉在多种尺度上的重要联系;② 从多种尺度上揭示了生态系统服务的状况与变化趋势;③ 制定提高人类福祉和保护生态系统服务的有效对策,需要考虑不同尺度上的驱动力和利益相关方的参与;④ 当地社区对生态系统服务的变化具有积极的适应与管理能力。此外,在对全球评估的概念框架的修改、对开展多尺度评估的利弊分析、多尺度评估需要克服的限制因素以及今后需要权衡与考虑的问题等方面,MA的多尺度评估也提供了宝贵的经验教训。 

Based on the findings of the Sub-global Assessments Working Group—Ecosystems and Human Welling-Being: Multiscale Assessments, the following contributions of multiscale assessments can be identified: ① Ecosystem services are important for many dimensions of human well-being, some of which are best observed at sub-global scales;② The condition and trends of many ecosystem services, observed at multiple scales, are declining in many locations worldwide;③ Identifying effective response options that enhance human well-being and conserve ecosystem services requires consideration of drivers at different scales and involvement of actors at the appropriate scales;④ Local communities are not mere spectators, but active managers of the capacity of ecosystems to deliver services. In addition, the following lessons can be learned for future assessments: ① The MA conceptual framework served as a valuable tool and initial point of reference, but had to be adapted by some sub-global assessments;② Multiscale assessments provide significant benefits, but they pose process and analytical challenges, are resource-and time-intensive, and, depending on assessment goals, may not always be necessary;③ For success, a sub-global assessment requires understanding of the context, adequate resources, champions and actively engaged users, and a governance structure able to manage competing needs;④ It is necessary for future assessments to conduct many tradeoffs and considerations.

Key words: Multiscale assessments    Contributions    Lessons.
