In order to comprehensively understand the research trends and hotspots in the field of soil contamination prevention and control in the globe,CiteSpace visualization software is used to analyze the publication volume,publication country,institution,highly cited literature and key word of soil contamination control research in the past 20 years.It is indicated that the number of articles published in both Chinese and English has grown steadily.In 2010,China surpassed the United States in terms of publication volume and became the country with the highest number of publications in this field.Chinese Academy of Sciences is the research institution with the highest number of publications,while collaboration among Chinese institutions is relatively sparse.Hot pollutants that attracted more attention in current research on soil remediation mainly include heavy metals,polycyclic aromatic hydrocarbons,petroleum pollutants and pesticides,while the remediation technologies focus on bioremediation and phytoremediation.Meanwhile,researchers have paid more attention to the source apportionment and health risk assessment of soil contamination in recent years.Green efficient remediation technologies such as bioremediation combined with genomics and biochar immobilization are the research highlight for soil pollution remediation at present and in the future.
