基于CNKI数据库的土壤重金属修复文献计量分析

    Bibliometrics Analysis on Soil Heavy Metal Restoration Based on CNKI Database

    • 摘要: 为深入了解土壤重金属修复研究现状,采用文献计量方法,以1999-2019年CNKI数据库收录的国内学术论文为对象,以SU=‘土壤重金属’AND SU=‘修复’为主题词,从年度发文量、基金来源、作者发文量、高被引论文以及关键词等方面对近20年土壤重金属修复领域的文献进行系统分析。结果表明:检索到1999-2019年有效文献共3 793篇,累计作者6 895人次;年度发文量呈飞速增长趋势,发文量居前3名的作者分别是周静、吴龙华、仇学亮;从基金来源分析,国家自然科学基金资助发文量高达611篇;从高被引论文和关键词分析,植物修复是土壤重金属污染修复的研究热点,镉、铅污染土壤修复是研究重点,生物炭修复重金属污染土壤是未来的发展方向。

       

      Abstract: In order to gain a deeper understanding of the research status of soil heavy metal restoration in related fields, the literature measurement method was adopted in this paper, by taking the domestic academic papers included in the CNKI database from 1999 to 2019 as the research object, and taking SU=‘soil heavy metal’ AND SU=‘repai’ as the subject headings, the literatures in the field of soil heavy metal restoration in the past 20 years were systematically analyzed from the aspects of the annual number of published papers, fund source, the number of published papers by author, highly cited papers and keywords. The results showed that a total of 3793 valid documents have been retrieved, with a total of 6895 authors. The annual number of articles published increased rapidly, and the top three authors were Zhou Jing, Wu Longhua and Qiu Xueliang. From the perspective of fund source, the National Natural Science Foundation of China subsidized the largest number of papers with 611. From the perspective of highly cited papers and keywords, the use of plant remediation was a research hotspot for the soil heavy metal pollution remediation. The remediation of soil contaminated by cadmium and lead was the research focus, and the remediation of soil contaminated by heavy metals through biochar was the future development direction.
