The term Blue Carbon (BC) was first coined a decade ago to describe the disproportionately large contribution of coastal vegetated ecosystems to global carbon sequestration. The role of BC in climate change mitigation and adaptation has now reached international prominence. To help prioritise future research, we assembled leading experts in the field to agree upon the top-ten pending questions in BC science. Understanding how climate change affects carbon accumulation in mature BC ecosystems and during their restoration was a high priority. Controversial questions included the role of carbonate and macroalgae in BC cycling, and the degree to which greenhouse gases are released following disturbance of BC ecosystems. Scientists seek improved precision of the extent of BC ecosystems; techniques to determine BC provenance; understanding of the factors that influence sequestration in BC ecosystems, with the corresponding value of BC; and the management actions that are effective in enhancing this value. Overall this overview provides a comprehensive road map for the coming decades on future research in BC science.
“蓝碳”一词是十年前首次提出的，用于描述沿海植被生态系统对全球碳固存的不成比例的巨大贡献。蓝碳在气候变化减缓与适应中的作用现在已引起国际关注。为了帮助确定未来研究的重点，我们召集了该领域的顶尖专家，就蓝碳科学中的十大待解决问题达成一致。了解气候变化如何影响成熟蓝碳生态系统及其恢复过程中的碳积累是当务之急。存在争议的问题包括碳酸盐和大型藻类在蓝碳循环中的作用，以及蓝碳生态系统受到干扰后温室气体释放的程度。科学家们寻求提高蓝碳生态系统范围的精确性；确定蓝碳来源的技术；了解影响蓝碳生态系统固碳的因素及其相应价值；以及增强这种价值的有效管理措施。总的来说，这份概述为未来几十年的蓝碳科学研究提供了一份全面的路线图。
