摘要:
自2009年,《蓝碳:健康海洋的固碳作用》发表以来,国际社会普遍认识到蓝碳在减缓和适应气候变化方面的价值,红树林、海草床和滨海盐沼进入了国家温室气体清单机制。《气候变化中的海洋与冰冻圈特别报告》(SROCC)将蓝碳作为海洋自然过程减缓的重要内容,指出易于管理的海洋系统所有生物驱动碳通量及存量可以被认为是蓝碳,并将大型海藻列为第四类海岸带蓝碳。报告评述了气候变化对蓝碳的影响,蓝碳减缓、适应气候变化等内容,指出蓝碳是大部分沿海国家当前“无悔的选择”。SROCC对蓝碳发展具有里程碑意义,我国加强蓝碳基础调查和研究,将蓝碳纳入国家温室气体清单和国家自主贡献,以蓝碳为抓手推动滨海湿地保护和恢复。

Abstract:
Since the release of Blue Carbon: the Role of Healthy Oceans in Binding Carbon in 2009, the international community has generally recognized the value of blue carbon in mitigating and adapting to climate change. Mangroves, seagrasses and coastal salt marshes have been incorporated into the mechanism of National Greenhouse Gases Inventory. The Special Report on Oceans and the Cryosphere in Climate Change (SROCC) takes blue carbon as a main mitigation way through natural ocean processes, states that all biologically-driven carbon fluxes and storage in marine systems that are amenable to management can be considered as blue carbon, and recognizes seaweeds as the fourth type of coastal blue carbon. The report reviewed the impacts of climate change on blue carbon, its mitigation and adaptation to climate change, and pointed out that blue carbon is the ries. SROCC is a milestone for blue carbon. China should strengthen its blue carbon investigation and research, incorporate blue carbon into the National Greenhouse Gas Inventory and Nationally Determined Contributions, and promote the protection and restoration of coastal wetlands with blue carbon as its starting point.
