基于科学知识图谱的国外数据库盐碱地领域文献研究分析

Analysis of foreign database literature on the field of saline-alkali land based on the scientific knowledge map

【目的】揭示盐碱地领域的发展现状和研究趋势。【方法】以2007—2017年Web of Science核心数据库中盐碱地领域文献为数据源,采用文献计量的方法统计分析了近10年盐碱地领域文献的发文量、国家、机构、载文期刊的情况;并用科学知识图谱VOSviewer软件对文献的国家合作、机构合作、作者合作、关键词聚类和新兴主题进行可视化分析,从宏观层面上划分盐碱地领域的研究方向。【结果】盐碱地领域的论文逐年快速增长,《INORGANIC CHEMISTRY》期刊载文量最多,形成了以HILL MICHAEL S、LI WENJUN和WESTERHAUSEN MATTHIAS为核心作者的合作网;科研成果最多的机构是中国科学院,且形成了以美国、中国、德国为核心的研究团体;近10年的热点关键词为晶体结构、复合物、水、钙、碱土等,近5年的新兴主题词为生物质、反应性、动力学、热解、性能等。【结论】近10年盐碱地领域的研究态势处于成长期。

【Objective】To reveal the development status and research trend of saline-alkali land field.【Methods】Using the literature on the field of saline-alkali land in the Web of Science core database from 2007 to 2017 as the data source,the method of bibliometrics was used to statistically analyze the number of publications,countries,institutions,and journals in the field of saline-alkali land in the past 10 years.The scientific knowledge map VOSviewer software was used to visually analyze the national cooperation,institutional cooperation,author cooperation,keyword clustering and emerging topics of the literature,and divided the research direction of the saline-alkali land field from the macro level.【Results】The number of papers on the field of saline-alkali land had been growing rapidly year by year,the largest number of the papers in the journal INORGANIC CHEMISTRY,formed a collaborative network with HILL MICHAEL S,LI WENJUN and WESTERHAUSEN MATTHIAS as the core authors.The institution with the most scientific research results is the Chinese Academy of Sciences,and had formed a research group centered on the United States,China,and Germany.The hot keywords in the past 10 years were crystal-structure,complexes,water,calcium,alkaline-earth etc.,and the emerging keywords in the past 5 years were biomass,reactivity,kinetics,pyrolysis,performance etc..【Conclusion】The research situation on the field of saline-alkali land in the past 10 years was in the growth stage.
