基于VOSviewer的2016—2021年间安全科学领域热点研究概况

An overview of hotspots research in the field of safety science from 2016 to 2021 based on VOSviewer

为深入了解安全科学领域的研究热点、研究现状及发展趋势,利用文献计量学分析方法,借助数据挖掘可视化软件VOSviewer及Web of science的核心数据库,从时间趋势、研究作者、机构与国际合作及期刊分布等方面对该库收录的安全科学技术领域的全球科学文献(2016—2021年)进行计量分析,并通过对此类文献高频关键词的统计,归纳研究热点。结果表明:自2015年以来,安全科学领域发表的文献数量持续增长;研究人员在安全风险分析方向的产出和贡献更加丰富;研究机构主要位于荷兰、美国、中国、澳大利亚等国家,其中论文发表量前十的机构中,中国高校及机构占一半;在统计的146个国家和地区中,前50国家和地区的累计论文量达到总量的95.53%,分布不平衡;灾害风险管理、计算机分析预测、自动驾驶汽车及工业安全生产等成为此研究领域中的新兴主题,而人为因素分析、煤矿自燃、车祸事故原因分析及朗缪尔模型等为安全领域中的研究热点;高被引论文更倾向于参考不同领域的研究方法,体现了安全学科的综合性。研究成果对把握安全科学领域研究方向、特点及发展现状提供参考。

The bibliometric analysis method was used to explore the research hotspots, research status and development trend in the field of safety science, via the data mining visualization software VOSviewer and the core database of Web of science.The global scientific literature in the field of safety science and technology(2016—2021)included in the database was quantitatively analyzed from the aspects of time trend, research authors, institutions, international cooperation, and journal distribution;the research hotspots were summarized by counting the high-frequency keywords of such literature.The results indicate that since 2015,the number of published literature in the safety sciences has continued to grow.The researchers have made more output and contributions in the direction of safety risk analysis.The research institutions are mainly located in the Netherlands, the United States, China, Australia and other countries.Among the top 10 institutions of published papers, the Chinese universities and institutions account for half.In 146 countries and regions, the cumulative papers of the top 50 countries and regions reached 95.53% of the total, and the distribution was uneven.Disaster risk management, computer analysis and prediction, autonomous vehicles, industrial safety production and so on have become the newly-emerging themes in this research field, and human factor analysis, coal mine spontaneous combustion, accident cause analysis, Langmuir model are the research topics in the field of safety.Highly-cited papers tend to refer to research methods in different fields, reflecting the comprehensiveness of safety disciplines.The research results provide a reference for grasping the research direction, characteristics and development status of safety science.
