基于文献计量分析的海洋观探测仪器技术发展态势研究

海洋观探测技术是海洋科学和技术的重要组成部分,对预警海洋灾害、开发海洋资源和空间、保护海洋环境、维护海洋权益、加强国防建设非常重要,海洋观探测仪器的研发是海洋观探测技术发展的重要基础和支撑。本文以Web of Science为数据统计源,基于战略咨询智能支持系统(ISS)平台和CiteSpace工具,通过文献计量和可视化分析,从发文量、涉及学科、作者、机构、关键词等方面对1998—2022年海洋观探测仪器技术论文进行了统计分析,总结了当前海洋观探测仪器技术领域的研究态势和研究热点,得出以下结论:(1)近10余年海洋观探测仪器技术研究呈快速增长趋势。虽然中国在该领域起步较晚,但发展迅速,2018年后发文量稳居世界第一,top 10高被引论文作者有3位是中国学者,中国研究学者在该领域具有较高影响力。但是发文量top 10机构多为美国研究机构,top 10高产作者中尚无中国学者,中国在该领域科研机构和研究人员的影响力和竞争力方面还需继续提高。(2)从词云聚类分析结果看,该领域全球研究热点集中在无人机、地磁仪、微波辐射计、海表温度和水色研究上。需要注意的是,ocean sensor关联词多为聚...

Analysis of developmental trends in ocean observation and detection instrument technology based on bibliometric analysis

Marine observation and detection technology is an important component of marine science and technology and plays an essential role in warning against marine disasters, developing marine resources and space, protecting the marine environment, safeguarding marine rights and interests, and strengthening national defense construction. Research on marine observation and detection instruments is important for developing marine observation and detection technology. This study clarifies the current research status and hotspots of instrument technology for marine observation and detection by first retrieving the related English articles published between 1998 and 2022 from the Web of Science and then statistically analyzing them in terms of the quantity of publications, disciplines involved, authors, institutions, keywords, and other aspects using bibliometric and visual analyses. The current research status and hotspots are summarized here. First, research on instrument technology for marine observation and detection has shown a rapid growth trend in the past decade. In China, research in this technological field began relatively late but rapidly developed. After 2018, it has steadily ranked first in the world in terms of the publication quantity of articles from Chinese researchers in this field. Three of the top ten authors of highly cited papers are Chinese scholars, showing that some Chinese researchers have a considerably influence in this field. However, in terms of publication quantity, most of the top 10 institutions are American institutions, and no scholar is Chinese by nationality among the top 10 high-yield authors. Hence, the influence and competitiveness of Chinese researchers in this field must be further improved. Second, the results of the word cloud clustering analysis show that the global research hotspots in this field are focused on unmanned aerial vehicles, magnetometers, microwave radiometers, sea surface temperature, and water color. Note that the association words of the ocean sensor are mostly keywords from the clustering analysis, indicating that the ocean sensor is a key research focus in this field. From the perspective of research focus evolution, despite starting late, China plays a certain leading role in the transfer of research hotspots on instrument technology for marine observation and detection due to its strong research tracking ability and rapid transfer of theme evolution.
