Coastal wetlands are the main distribution of blue carbon in coastal zones and well known for their high carbon sequestration capacity. Investigating the variation of carbon budget is crucial for understanding the functionality of coastal wetlands and effectively addressing climate change. In this study, a bibliometric analysis of 4,509 articles was conducted to reveal research progress, hot issues, and emerging trends in the coastal wetland carbon budget field. The number of publications and citations in this field increased exponentially from 1991 to 2022. The leading subject category was Environmental Sciences with 1,844 articles (40.9%). At present, studies have been focused on blue carbon, the effects of climate change and man-made disturbances on carbon cycle, and the restoration of coastal wetlands. Based on the hotspots and trends in this field, the future researches should include (1) exploring the functional mechanisms of various factors affecting carbon cycle and establishing a methodological system for the estimation of blue carbon in coastal wetlands; (2) researching restoration techniques of coastal wetland and constructing wetland restoration evaluation index system; and (3) formulating enforceable carbon trading policy and strengthening international cooperation.
滨海湿地是滨海区蓝碳的主要分布区，以其高碳封存能力而闻名。调查碳收支变化对于了解滨海湿地的功能和有效应对气候变化至关重要。本研究通过文献计量分析，对 4509 篇文章进行了分析，以揭示滨海湿地碳预算领域的研究进展、热点问题和新兴趋势。1991 年至 2022 年，该领域的出版物和引文数量呈指数级增长。主导的主题类别是环境科学，有 1844 篇文章（40.9%）。目前，研究集中在蓝碳、气候变化和人为干扰对碳循环的影响以及滨海湿地的恢复上。基于该领域的热点和趋势，未来的研究应包括：（1）探索影响碳循环的各种因素的功能机制，建立滨海湿地蓝碳估算的方法体系；（2）研究滨海湿地的恢复技术，构建湿地恢复评价指标体系；（3）制定可行的碳交易政策，加强国际合作。
