有机气溶胶(organic aerosol，OA)是全球PM2.5的重要组分(质量占比20%～90%)，也是影响气溶胶特性的关键成分之一，对环境、气候和人体健康都具有负面影响。文献计量学通过对文献数量、时空分布及学术关联关系进行定量分析，以揭示特定研究领域的整体特征与发展趋势。基于此，本文以“organic aerosol*”为主题词进行文献计量学统计，在Web of Science核心合集中的SCIE和SSCI数据库进行检索，时间限制在1900年1月1日—2024年11月23日，共计12 878篇相关文献，并以此作为数据基础。通过自然语言处理、词云分析、词频分析及社会网络分析等方法，探讨OA领域的研究现状及发展趋势。结果表明，OA相关研究自1993年后逐步展开，发文量排名前三的国家分别为美国、中国、德国。期刊发文量则以Atmospheric Chemistry and Physics最多。研究机构按地区主要集中在欧洲、美国和中国。University of California System(加州大学系统)等是国外著名的研究机构，而国内代表性的研究机构有中国科学院、北京大学、清华大学等。OA领域的核心研究内容可以归纳为形成机制、来源解析、化合物组成，近年其发展趋势十分明确：气溶胶来源解析、质谱技术应用、示踪物特征、前体物化学转化过程、模型模拟及光学特性都是热点方向。本文首次将社会网络分析方法应用于OA领域的文献计量学研究，总结了OA领域研究现状及发展方向，突出了OA在环境地球科学研究中的重要潜力。
Abstract：Organic aerosol (OA) is an important component of global PM2.5 (mass ratio of 20% ～ 90%) and one of the key components affecting aerosol characteristics， which has a negative impact on the environment， climate and human health. Bibliometrics reveals the overall characteristics and development trends of specific research fields by quantitatively analyzing the number， spatial and temporal distribution and academic correlation of literatures. Based on this， this paper uses “organic aerosol*” as the subject word for bibliometric statistics， and searches the SCIE and SSCI databases in the core collection of Web of Science. The time limit is from January 1， 1900 to November 23， 2024. A total of 12，878 related literatures are used as the data basis. Through natural language processing， wordcloud analysis， word frequency analysis and social network analysis， the research status and development trend of OA field are discussed. The results show that OA-related research has been gradually carried out since 1993， and the top three countries in the number of publications are the United States， China and Germany. Atmospheric Chemistry and Physics published the most papers. The research institutions are mainly concentrated in Europe， the United States and China by region. The University of California System is a famous research institution abroad， and the representative research institutions in China include the Chinese Academy of Sciences， Peking University， Tsinghua University and so on. The core research contents in the field of OA can be summarized as formation mechanism， source apportionment and compound composition. In recent years， its development trend is very clear: aerosol source apportionment， mass spectrometry technology application， tracer characteristics， precursor chemical conversion process， model simulation and optical properties are all hot topics. In this paper， the social network analysis method is applied to the bibliometric research in the field of OA for the first time. The research status and development direction of OA are summarized， and the important potential of OA in environmental geoscience research is highlighted.
