Abstract

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
