2000—2020年我国镉吸附-解吸的文献计量研究——基于CiteSpace的计量分析

Research Progress of Cadmium Adsorption-desorption in 2000—2020 in China—Quantitative Analysis Based on CiteSpace

以中国知网(CNKI)全文数据库中2000年1月1日—2020年7月22日的618篇镉吸附-解吸相关文献作为数据源,运用文献计量及可视化的方法,对发文量、载文期刊、发文机构、关键词、发文作者进行分析。结果表明,我国近20年在该领域的中文发文量整体不高,年均发文量不足35篇;期刊刊文量前3名是《湖南大学学报》《农业环境科学学报》和《成都理工大学学报》;排名前3的发文机构是中国科学院沈阳应用生态研究所、西南大学资源环境学院、中国科学院研究生院;关键词分布知识图谱显示,“吸附”“解吸”“重金属”“重金属离子”“土壤”“Cd 2+”等为起连接作用的核心关键词;排名前3的作者是刘世亮、刘芳、化党领;通过热点关键词突现图可知,有机酸和生物质炭为近20年国内应用到镉吸附-解吸领域的物质,褐土和红壤则为关注的土壤类型。

The 618 literatures related to cadmium adsorption and desorb(CAJON)in the CNKI full-text database were used as the data sources for analysis of the related entries,periodicals,publishers,keywords and authors by using the methods of literature measurement and visualization.The results showed that the number of Chinese articles published in this field in the past 20 years was not high on the whole,which was less than 35 articles per year.Journal of Hunan University,Journal of Agricultural And Environmental Science and Journal of Chengdu University of Technology were the top three publications.The top three publications were Shenyang Institute of Applied Ecology,Chinese Academy of Sciences,School of Resources and Environment,Southwest University,and Graduate School of Chinese Academy of Sciences.The knowledge map of key word distribution shows that adsorption,desorption,heavy metal,heavy metal ion,soil,Cd 2+were the core keywords that played the role of connection.The top three authors were Liu Shiliang,Liu Fang and Hua Dangling.According to the flash-figure of hot keywords,organic acids and biomass charcoal were the substances that had been applied in the field of cadmium adsorption-desorption in China in the past 20 years,while brown soil and red soil were the soil types concerned.
