为全面了解国内外土壤污染防治的研究趋势和热点,利用CiteSpace可视化软件分析了近20年土壤污染治理研究相关文献的发文量、发文国家、发文机构、高被引文献和关键词等。结果表明,中英文发文量呈稳定增长趋势,中国于2010年发文量超过美国而成为该领域发文量最多的国家;中国科学院是发文量最多的机构,但国内机构间的合作较为稀疏;当前土壤污染治理中热点污染物主要侧重于重金属、多环芳烃、石油污染物和农药方面,修复技术则聚焦于生物修复和植物修复方面;学者们近几年更关注土壤污染的来源解析和健康风险评估等;结合基因组学的生物修复、生物炭钝化等高效绿色修复技术是当下和未来土壤污染修复的研究重点。

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.
