| Abstract: |
| To investigate the current status in the field of heavy metal-contaminated soil remediation, this study analyzed the development of relevant literatures from 1998 to 2018 using CiteSpace as a bibliometric tool. The results showed that the number of publications on soil heavy metal remediation has grown rapidly over the study period. The five countries with the most published papers included China, Spain, Italy, South Korea, and the United States of America. The main journals in foreign language literature included Chemosphere, Journal of Hazardous Materials, and Environmental Science and Pollution Research. The main Chinese-language journals included Journal of AgroEnvironment Science and Ecology and Environment Sciences. In terms of the number of articles published in foreign languages and the frequency of citation of papers, Chinese scientific research institutions occupied an important position, indicating that China had strong international academic influence in this research field. The frequency of keywords occurrence and citation of literature indicated that accumulation characteristics and remediation of cadmium, lead, zinc, and copper in soil were the main focuses of research in this field. In addition, research in phytoremediation and the application of biochar in repair of heavy metal-contaminated soil were currently popular research topics in this field. Research of new repair technology, comprehensive repair systems, and repair mechanisms and demonstration of practical heavy metal repair in actual farmland soil are important future directions in this field. |
