摘要:

碳元素在海洋中以多种形式参与全球碳循环, 其中海洋沉积物埋藏的有机碳(total organic carbon, TOC)在全球碳循环中起到至关重要的作用。边缘海作为全球海洋物理能量和生产力较高的过渡区, 储存了全球海洋80%以上的有机碳。中国边缘海总面积约470×104km2, 具有显著的储碳能力和前景, 随着我国“双碳”目标的实施, 海洋储碳相关研究成为近年来的研究热点。文章综述了中国边缘海沉积物有机碳分布特征, 整体上呈现出从渤海向南海逐渐增加的趋势, 且沿岸海域和河流入海口周围含量显著高于远海。同时分析了有机碳主要来源和影响因素及其储碳潜力, 并对未来可能的重点研究方向进行了展望, 旨在为国内边缘海储碳和碳循环方面的相关工作提供一定的借鉴。

Abstract:

Carbon participates in the global carbon cycle in various forms in the ocean, with total organic carbon (TOC) buried in marine sediments playing a crucial role. As a transition zone characterized by high physical energy and productivity, marginal seas store more than 80% of the organic carbon in the global ocean. Covering a total area of about 4.7 million square kilometers, China’s marginal seas possess significant carbon storage capacity and potential. With the implementation of China’s “Dual Carbon” initiative, research on marine carbon storage has become a prominent topic in recent years. This review summarizes the distribution characteristics of organic carbon in the sediments of China’s marginal seas, revealing a decreasing tendency from the Bohai Sea to the South China Sea. Notably, organic carbon content in coastal waters and near estuaries is significantly higher than in the deep sea. In addition, the main sources, influencing factors, and storage potential of organic carbon are analyzed. Moreover, the review provides an outlook on potential future research directions, aiming to offer insights for the related work on marine carbon storage and the carbon cycle in China’s marginal seas.

Key words: marginal seas, total organic carbon, rivers, currents, carbon storage potential
