基于文献计量的海洋碳汇研究热点与趋势分析

Analysis of Hot Spots and Trends in Ocean Carbon Sink Research Based on Bibliometrics

海洋作为最大的碳库,研究海洋碳汇对实现“双碳”目标、应对气候变化以及开发海洋经济有重大意义。当前国内外海洋碳汇研究较为零散,从文献计量的角度出发,运用知识图谱可视化的形式梳理海洋碳汇研究态势,在厘清海洋碳汇相关科学概念的基础上,对海洋碳汇的研究进展进行了量化分析,研究结果表明:(1)海洋碳汇的相关文献量整体呈现上升趋势,部分领域的研究已相对深入;(2)该研究领域核心作者较少,导致推动该领域的研究动力不足,且研究机构间的合作联系较弱,需进一步加强;(3)当前海洋碳汇研究热点主要聚焦在海岸带生态碳汇、碳汇渔业、碳汇养殖、碳汇交易等方面,研究前沿呈现主题融合趋势。同时,结合研究现状和热点,从海洋碳汇研究发展的系统化、多元化和时代化方向出发,预测了海洋碳汇研究的发展趋势,以期为相关学者的研究提供参考。

As the largest carbon pool,the study of ocean carbon sinks is of great significance for achieving the"double carbon"target,coping with climate change and developing ocean economy.In view of the fragmented research on ocean carbon sinks at home and abroad,this paper compares the research trend of ocean carbon sinks from the perspective of bibliometrics and uses knowledge mapping visualization to quantify and analyze the research progress of ocean carbon sinks on the basis of clarifying the scientific concepts related to ocean carbon sinks.The research results show that:(1)the overall volume of literature on ocean carbon sinks is on the rise,and the research in some fields is relatively in-depth;(2)There are few core authors in this research area,which leads to insufficient motivation to promote research in this area,and the cooperation and links among research institutions are weak and need to be further strengthened;(3)The current research hotspots of marine carbon sinks mainly focus on coastal ecological carbon sinks,carbon sink fisheries,carbon sink farming,carbon sink trading,etc.,and the research frontier shows a trend of thematic integration.At the same time,the development trend of marine carbon sink research is predicted from the direction of systematization,diversification and modernization of marine carbon sink research development,in order to provide reference for the research of related scholars.
