摘要:

为系统梳理2004—2023年可溶性有机碳研究的发展动态、热点演变及前沿方向,基于Web of Science和CNKI数据库,系统检索并筛选2004—2023年发表的3003篇相关文献。使用VOSviewer、CiteSpace等文献计量工具,构建涵盖发文国家、机构、关键词等维度的可视化知识图谱。结果发现,可溶性有机碳主题相关研究论文发表数量呈现逐年增加趋势,中国科学院是该领域发文量最多的科研机构。中美两国主导全球研究产出(美国748篇,中国556篇),并形成密切国际合作网络。研究热点主要聚焦于农业土壤和环境保护,研究范畴从土壤环境拓展至河流、湖泊、海洋等水生系统,并日益关注气候变化影响和生物可利用性等关键议题。本研究系统揭示了可溶性有机碳研究的核心力量、热点主题的时空演变规律及关键文献,可为厘清该领域研究脉络、识别未来方向提供计量学依据和实践参考。

Abstract:

To systematically elucidate the developmental trends, evolving research foci, and frontier directions in dissolved organic carbon (DOC) studies from 2004 to 2023, a comprehensive retrieval and screening process was conducted utilizing the Web of Science and CNKI databases, resulting in the identification of 3003 relevant publications. Bibliometric analysis was performed using visualization tools including VOSviewer and CiteSpace to construct knowledge maps encompassing dimensions such as contributing countries, institutions, and keywords. The results indicate a consistent annual increase in the volume of published research on DOC. The Chinese Academy of Sciences was identified as the most prolific research institution in this field. Globally, research output is predominantly led by the United States (748 publications) and China (556 publications), which have established close international collaborative networks. Research hotspots primarily concentrate on agricultural soils and environmental protection, with the scope of investigation expanding from terrestrial environments to aquatic systems including rivers, lakes, and marine ecosystems. Furthermore, increasing scholarly attention is being directed toward critical issues such as climate change impacts and bioavailability. This study systematically delineates the core research entities, spatiotemporal evolution of key themes, and seminal literature in DOC research, thereby providing a bibliometric foundation and practical reference for clarifying research trajectories and identifying future directions in this field.
