摘要： 碳元素在海洋中以多种形式参与全球碳循环，其中在全球碳循环中海洋沉积物埋藏的有机碳（total organic carbon, TOC）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470万平方千米，具有显著的储碳能力和前景，随着我国“双碳”计划的实施，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、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 many forms in the ocean, in which total organic carbon (TOC) buried in marine sediments plays a crucial role in the worldwide carbon cycle. As a transition zone with high physical energy and productivity worldwide, the marginal sea stores 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 sea has significant carbon storage capacity and prospects. With the implementation of China's “Double Carbon” program, the study related to marine carbon storage has become a hot research topic in recent years. The review summarizes the distribution characteristics of organic carbon distribution, main sources, and influencing factors, as well as the potential of carbon storage in the marginal sea sediments of China. In addition, the review also provides an outlook on the possible future research directions, aiming at providing certain references for the related work on marine carbon storage and carbon cycle in China's marginal sea.
