摘要：

归纳空气负（氧）离子研究进展和前沿热点,旨在为未来研究提供参考。基于Web of Science核心数据库以“air negative oxygen ion”为检索对象,获取2002—2019年收录的空气负（氧）离子文献,并通过知识图谱展现18年间其发展历程。结果表明,2002—2019年Web of Science数据库共收录相关文献285篇,文献发表数量年平均增长率为7.08%,合作指数为4.54,期间出现了许多高产论文作者和高被引论文,期刊影响因子高和被引频次高的文献更容易被其他作者引用。空气负（氧）离子文章来源期刊的大类学科以物理、工程技术和化学等学科为主,其中在《Journal of Physics D: Applied Physics》期刊上发表数量最多,总计12篇。空气负（氧）离子文章相关高频关键词主要为氧、空气、性能、氮、放电和等离子体等,等离子体、电池、石墨烯等新能源、新材料的应用则是近年来该领域研究的热点。中国作者发文量、文章被引用量、中外合作发表文章数量较高,但文章篇均被引用量较低。中外作者在该领域研究方向上存在差异,国内以空气负（氧）离子与森林康养、环境因子的关系为主,国外以空气负（氧）离子在化学、工业、医疗方面的应用为主。

Abstract:

The study aims to provide a reference for the future research on negative air (oxygen) ions by summarizing its research progress and frontier topics. Based on the Web of Science core database with ‘air negative oxygen ion’ as the search object, we got the literature on air negative (oxygen) ion from 2002 to 2019, and studied its development history in the 18 years through the knowledge graph. The results show that the Web of Science database includes 285 relevant documents in 2002-2019, with an average annual growth rate of 7.08% and a collaboration index of 4.54. There are many highly productive authors and highly cited articles, and articles from journals with high impact factors and with high citation counts are more likely to be cited by other authors. The major disciplines of the air negative (oxygen) ion source journals are physics, engineering technology, and chemistry, with 12 articles published in Journal of Physics D: Applied Physics, which is the largest number. Related high-frequency keywords from air negative (oxygen) ion articles are mainly about oxygen, air, performance, nitrogen, discharge, plasma and so on, the application of new energy and materials (e.g., plasma, batteries, graphene) is a hot topic in recent years. The Chinese authors have relatively a large number of published articles, citations and collaboration with authors from abroad, but their number of citations per article is relatively low. There are differences in the research field between Chinese and foreign authors. In China, the main focus is on the relationship between air negative (oxygen) ions and forest therapy and environmental factors, while in foreign countries, the application of air negative (oxygen) ions in chemistry, industry and medical treatment is the main research focus.

Key words: air negative (oxygen) ions, knowledge map, Web of Science, development trend, forest therapy, forest environment
