摘要：

为了解土壤重金属污染防治在全球的研究趋势及热点,基于CiteSpace软件,以Web of Science数据库核心合集、中国知网、维普和万方核心期刊为数据源,从发文数量、作者、机构、关键词以及共被引文献多个方面对2006—2019年国内外发表的土壤重金属污染防治方面的文献进行可视化分析。结果表明：（1）2006—2019年中英文文献发文量稳定增长,未来可能继续保持增长的势头。（2）农业产业为支柱的国家或地区更加重视农田土壤重金属污染,其英文发文量位居前列,如中国、美国、西班牙和印度等。中国科学院大学是中文发文量最多的研究机构,中国科学院是英文发文量最多的研究机构,可见中国在该领域具有一定的学术影响力。然而,与国际研究机构相比,中国企业、高校、研究所之间仍需进一步加强学术交流合作。（3）土壤中镉、铅、锌、铜这4类重金属的污染修复发文量最多,植物修复、淋洗修复、生物炭修复等是当前国内外的研究热点。相对于其他的土地利用类型,农田土壤污染是国内重点修复对象,这与国家或地区对农田土壤环境质量和农产品安全的重视密不可分。中国土壤污染的风险评价和防控体系尚不健全,仍需要进一步深入研究。

Abstract:

To understand the global research trends and hotspots of soil heavy metal pollution prevention and control, the CiteSpace was used for a visualized analysis of the number of articles, authors, institutions, keywords, and the co-cited network of documents from 2006-2019 on soil heavy metal pollution control based on the literature from the core collections of the Web of Science database, CNKI, VIP and Wanfang. The results showed that the literature items of Chinese and English increased steadily from 2006 to 2019, which probably would continue to increase in the future. Countries with the largest number of papers have leading agricultural industry, such as China, the United States, Spain and India. The University of Chinese Academy of Sciences was the research institution with the largest number of Chinese publications, while the Chinese Academy of Sciences was the research institution with the highest number of English publications, indicating that China had strong academic influence in this research field. Compared with international research institutions, Chinese companies, universities and research institutions should further strengthen academic exchange and cooperation. The largest number of studies was about heavy metals of cadmium, lead, zinc and copper, and current research hotspots of remediation methods were phytoremediation, leaching remediation and biochar remediation. Meanwhile, most domestic researches were carried on farmland soil compared with other types of soil, which might be closely related to the importance given by national and local government to soil environment quality and agricultural product safety. The soil risk assessment and pollution control system have not been well built in China yet, which should be further explored.

Key words: CiteSpace, heavy metal, prevention and control, remediation, soil
