国际生态脆弱性研究态势的文献计量分析

Bibliometric Analysis of International Ecological Vulnerability Research Situation

基于Web of Science数据库对生态脆弱性文献进行检索,选取1973年至2018年的文献作为研究对象,运用bibexcel、Ucient、Netdraw以及SPSS文献计量分析软件对文献进行较为全面的分析,确定国际生态脆弱性的研究态势。首先运用bibexcel得出生态脆弱性研究关键词共现矩阵,其次通过Ucient得到生态脆弱性研究关键词网络共现可视化图,最后通过SPSS得出生态脆弱性研究领域关键词群集。研究表明:(1)生态脆弱性研究从2000年以来,总体趋势处于上升状态,美国、中国为生态脆弱性研究的领军国家;(2)生态脆弱性评估、风险评价关键词频次较高,为生态脆弱性研究的核心;其中恢复力、适应能力、生物多样性、保护措施为当今研究热点;(3)通过聚类分析,国际生态脆弱性研究集中在各类生态系统脆弱性、生物体脆弱性、风险评估和环境与可持续发展四个群集。

Based on the web of science database,the literature on ecological vulnerability was searched.The literature from 1973 to 2018 was selected as the research object,and the literature was analyzed comprehensively by using the software of Bibexcel Ucient,Netdraw and SPSS to determine the research situation of international ecological vulnerability.Firstly,the cooccurrence matrix of ecological vulnerability research keywords is obtained by using bibexcel.Secondly,the cooccurrence visualization map of ecological vulnerability research keyword network is obtained by Ucient.Finally,the key words cluster in ecological vulnerability research field is obtained by SPSS.Research shows that:(1)Since 2000,the overall trend of ecological vulnerability research has been on the rise with the United States and China as the leading country in ecological vulnerability research;(2)Ecological vulnerability assessment,with high frequency of key words in risk assessment,is the core of ecological vulnerability research,in which resilience,adaptability,biodiversity and conservation measures are the focus of current research;(3)Through cluster analysis,international ecological vulnerability studies focus on four clusters:ecosystem vulnerability,organism vulnerability,risk assessment and environment and sustainable development.
