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
