摘要:
土壤污染已经成为全球性问题,也是中国环境危害最为严重的问题之一。本文数据来源于中国知网(CNKI)和Web of Science (WOS)数据库,利用CiteSpace软件对2011—2020年土壤修复研究领域的文献进行可视化分析,探讨了土壤修复相关研究的现状及未来发展趋势。研究表明:土壤修复领域的研究(1)发文量总体呈上升趋势,中国、美国、西班牙、印度、澳大利亚是英文发文量位居前5的国家;中国以科学院为主要发文机构;(2)从关键词的中心性和文献被引频次分析得到重金属污染土壤及修复是目前主要的研究内容,而生物修复及生物炭是土壤修复领域的研究热点(3)农药污染土壤修复、生态修复、修复材料及修复技术的研发是未来土壤修复研究领域的重要方向。

Abstract:
Soil pollution has become a global problem and is one of the most serious environmental problems in China. To discuss the current status and future development trend of soil remediation, the present study visually analyzed the information of related literature from 2011 to 2020 collected from CNKI and Web of Science (WOS) by using CiteSpace software. The results indicated that, for research in soil remediation field from 2011 to 2020: (1) the number of publications had increased gradually, five countries with the top English publication numbers were China, the United States, Spain, India and Australia, the Chinese Academy of Sciences was the main institution contributing to the number of publications in China; (2) the centrality of keywords and the frequency of literature citation showed that the research focus in this field was on the remediation of contaminated soil caused by heavy metal, while bioremediation and biochar were research hotspots; (3) the remediation of pesticide-contaminated soil, ecological remediation, research and development of restoration material and technology will be important directions in soil remediation research in the future.
Key words: soil, pollution, remediation, CiteSpace, visual analysis, research hotspots
