摘要：为全面了解国内外镉污染土壤修复领域的研究现状及前沿动态,以Web of Science数据库及中国知网的文献资料(截至2024年5月13日)为数据源,利用CiteSpace文献计量工具进行可视化分析。结果表明:国内学者发表的文献数量增长迅速,且明显多于国外。国内文献发文量呈现先慢后快的趋势,尤其在2014年后增速显著。国内外文献作者和研究机构联系均较弱,其中国外文献作者和机构形成了以法国、印度为中心的合作网络关系,发文作者群体分布离散;国内则以各大高校和部分研究所为主导力量,呈多中心、分散式的结构模式。关键词可视化结果表明,国内外研究同步性较强,均以土壤镉污染的健康影响和解决策略为基础。植物修复、生物修复和健康风险评估是目前国外研究热点,国内则以植物修复、联合修复以及钝化材料筛选与应用为研究热点。研究发展脉络从最初的镉污染源解析到土壤镉的累积特征发展到现在的修复技术与材料的研发及健康风险评估。深入探究联合修复技术、研发和应用绿色无污染和安全可持续修复材料是未来镉污染土壤修复领域研究的重点,健康风险评估模型构建也迫在眉睫。
To comprehensively understand the current research status and cutting-edge dynamics in the field of cadmium-contaminated soil remediation at home and abroad,the literature from the Web of Science database and the China Knowledge Network(as of May 13,2024)was used as the data source,and the CiteSpace bibliometric tool was used to conduct the visualization and analysis.The findings indicate that the number of publications by domestic scholars is increasing rapidly and significantly surpasses that of foreign countries.The volume of domestic literature has exhibited an initial gradual rise,followed by a subsequent rapid growth,particularly after 2014,when the growth rate became substantial.A closer look reveals that domestic and foreign literature authors and research institutions exhibit a lack of connectivity,with foreign literature authors and institutions having established a cooperative network centred on France and India,characterized by a dispersed distribution of the group of issuing authors.In contrast,domestically,major universities and select research institutes dominate,displaying a polycentric and decentralized structural pattern.The analysis of keyword visualization reveals a greater synchrony between domestic and international studies,focusing on the health impacts and solution strategies of soil cadmium pollution.The present state of research in the field is marked by a concentration on phytoremediation,bioremediation,and health risk assessment in foreign countries,as well as on phytoremediation,joint remediation,and the screening and application of passivation materials in China.Research development has evolved from the initial analysis of cadmium pollution sources to the cumulative characteristics of soil cadmium to the current development of remediation technologies and materials and health risk assessment.The future direction of research in the field of cadmium-contaminated soil remediation will centre on in-depth investigations of joint remediation technology,research and development,and the application of green,non-polluting,and safe remediation materials.Additionally,the development of health risk assessment models is anticipated to play a significant role in the near future.
