基于Citespace的国内外碳汇研究热点与前沿分析

Research progress and frontier analysis of carbon sink at home and abroad based on Citespace

随着全球气候变化不断加剧,生态系统的碳汇功能被政府、社会及学术界持续关注。本文以国内外碳汇相关文献为研究对象,运用Citespace对WebofScience(WOS)核心合集数据库和中国知网(CNKI)数据库中收录的文献进行可视化分析。结果表明美国在碳汇领域的发文量和影响力均为最高,而我国发文量呈快速上升趋势,其中中国科学院的研究较为突出,但国际影响力相对较低。国外碳汇领域研究热点侧重在二氧化碳、气候变化、浮游植物、涡度相关法、碳封存和光合作用等方面,国内研究的侧重在碳储量、碳中和、低碳经济、碳循环和碳排放等方面。国外碳汇领域的研究前沿包括有碳汇影响因素、全球干旱、评估模型等方向,国内的研究前沿包括红树林、蓝碳、碳汇影响因素、乡村振兴、实物期权等方向,我国需不断强化国际合作,并加强碳汇机理性研究,争取早日实现“双碳”目标。

With the increasing global climate change,the carbon sink function of ecosystems has been continuous⁃ly concerned by the government,society and academia.This article takes carbon sink at home and abroad literature as the research object,Visualize and analyze the literature included in the Web of Science(WOS)core collection database and China National Knowledge Infrastructure(CNKI)database by using the Citespace.The results show that the United States has the highest number of publications and influence in the field of carbon sinks.While the number of publica⁃tions in China showed a rapid upward trend,among which the research of the Chinese Academy of Sciences is more prominent but the international influence was relatively low.Foreign research focuses on carbon dioxide,climate change,phytoplankton,vorticity correlation method,carbon sequestration and photosynthesis,while domestic research fo⁃cuses on carbon storage,carbon neutrality,low-carbon economy,carbon cycle and carbon emissions.The research fron⁃tiers in the field of carbon sequestration abroad include factors affecting carbon sequestration,global drought,and assess⁃ment models.The research frontiers in China include mangroves,blue carbon,factors affecting carbon sequestration,rural revitalization,and real options.China needs to continuously strengthen international cooperation and strengthen rational research on carbon sequestration mechanisms,in order to achieve the"dual carbon"goal as soon as possible.
