【摘要】 湿地碳汇在降低大气中温室气体含量、缓解全球气候变暖方面发挥着积极作用。为了全面掌握湿地碳汇研究的当前状况和发展动向，本研究选取了Web of Science核心合集和CNKI数据库作为基础数据源，并运用CiteSpace知识图谱分析工具，对2000—2024年间国内外在湿地碳汇领域的文献发文时间、研究团队、发文机构、研究热点以及发展趋势进行了可视化分析。研究结果显示：1)国内外关于湿地碳汇研究发文量进展相似，总体上均呈现增长趋势，中国和美国是发文数量最多的2个国家，中国科学院发表的论文数量居于领先地位；2)国内外该领域研究团队及机构组团之间合作较为紧密，学科交叉性日益增强，但大范围的合作网络仍需进一步发展；3)国内外湿地碳汇研究的核心内容基本一致且呈现多元化趋势，但研究领域始终聚焦于湿地碳封存能力以及如何应对气候变化这2个关键问题上，并且特别强调滨海湿地等海洋碳汇的关键作用。当前，湿地碳汇研究正处于蓬勃发展的阶段，研究的广度和深度持续拓展。展望未来，亟须进一步强化湿地碳汇的监测工作，提升碳汇能力，并确保相关政策的有力支持，以推动该领域的研究向更深层次、更高水平迈进。更多还原

【Abstract】 Wetland carbon sink play a crucial role in reducing the greenhouse gas concentration in the atmosphere and mitigating global climate change.To comprehensively understand wetland carbon sequestration’s current status and developmental trend, this study employs the Web of Science core collection and the CNKI database as foundational data sources.Utilizing the CiteSpace knowledge graph analysis tool, the research conducted a visual analysis of the publication timelines, research teams, publishing institutions, research hotspots, and development trends in wetland carbon sequestration from 2000 to 2024.The results indicate that: 1)The progression of publication volume on wetland carbon sequestration is similar both domestically and internationally, with an overall upward trend; China and the United States are the leading countries in terms of publication quantity, with the Chinese Academy of Sciences ranking first in the number of papers published in the number of published papers; 2)Research teams and institutions in this field exhibit close collaboration within their respective groups, with an increasing interdisciplinary approach; However, the large-scale cooperation network still requires further developed; 3)The core content of wetland carbon sequestration research is internationally consistent and shows a diversified trend.Nevertheless, the focus remains on two key issues: The carbon sequestration capacity of wetlands and responses to climate change, with a particular emphasis on the core role of marine carbon sequestration, such as coastal wetlands.Currently, research on wetland carbon sinks is experiencing robust growth, with expanding breadth and depth, and it is necessary to strengthen the research on wetland carbon sink monitoring, carbon sink capacity improvement, and policy guarantee in the future.更多还原
