| 摘 要： | 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。

| Abstract: | The Arctic carbon sink was always ignored in the global carbon budget or dealt with in a simple way because the central Arctic was covered by ice year long. This view has changed, however, recently. With the increasing rates of global changes, the Arctic Ocean also changes. It becomes clearer that it is of paramount importance to understand the interplay between the carbon cycle in Arctic Ocean. This paper summarizes the current results on Arctic carbon sink (ACS), analyzes sources, variations and the controlling factors of the ACS, and then estimates the current status of ASC. The trend of ACS variation in the future is also evaluated here. |
