基于知识图谱的自然灾害风险防控研究进展的文献计量分析

为分析自然灾害风险防控研究发展状况及趋势,以2003-2017年Web of Science核心合集中SCI-EXPANDED数据库收录的1 159篇自然灾害风险防控研究文献作为数据基础,利用VOSviewer和Bibexcel软件,采用共引分析、耦合分析、共著分析、词频统计和共现分析等文献计量可视化分析方法,通过文献发表的时间分布、区域分布、学科和期刊分布、文献代表作者、合作机构、研究热点等方面的分析,综述了自然灾害风险防控研究进展。结果表明:近年来,自然灾害风险防控研究热度上升迅速;美国在该领域的发文量明显领先,中国则具备了赶超的潜力;各研究机构中,北京师范大学、中国科学院、悉尼大学、京都大学等是该领域的领军机构;从发展趋势上看,该领域已形成了"水旱灾害管理""灾害风险防控""灾害脆弱性""灾害影响"4个重要的研究热点和前沿方向,其中"灾害风险防控"把其他3类热点紧密关联起来,形成了一个结构紧凑的自然灾害风险防控研究知识图谱系统。上述结果揭示了自然灾害风险防控研究的演变特征与发展趋势,有助于加深对自然灾害风险防控研究领域的整体认识。

Bibliometric Analysis of Research Progress in Natural Disaster Risk Prevention and Control Based on Knowledge Graph

In order to analyze the status of natural disaster risk prevention and control research and explore its development trend,this paper used 1159 natural disaster risk prevention and control research literatures included in the SCI-EXPANDED database from the 2003-2017 Web of Science Core Collection (hereinafter referred to as WOS) as data,based on VOSviewer and Bibexcel software,used co-citation analysis,coupling analysis,co-autho-ring analysis,word frequency statistics and co-occurrence analysis to visualize the bibliometric analysis,reviewed the literature on the natural disaster risk prevention and control through six aspects : time distribution,regional distribution,subject and journal distribution,literature representative authors,cooperative institutions,and research hotspots.The results show that the research on natural disaster risk prevention and control has risen rapidly;the U-nited States has a clear lead in this field,China has the trend of catching up with the United States in recent years;the leading units in this field include Beijing Normal University,Chinese Academy of Sciences,University of Sydney,Kyoto University,etc.;the field has formed four important research hotspots and frontier directions of water and drought disaster management,disaster risk prevention and control,disaster vulnerability and disaster impact,where disaster risk prevention and control closely links the other three hotspots and forms a compact knowledge map system for natural disaster risk prevention and control research.The above results reveal the evolution characteristics and future development trends of natural disaster risk prevention and control research,and help to deepen the overall understanding of natural disaster risk prevention and control research.
