摘要
近年来,土壤环境中抗生素抗性基因(ARGs)污染引起广泛关注.以Web of Science核心数据库和万方数据库文献资料为数据源进行文献计量学分析,从年发文量变化、不同国家贡献及研究主题演变(基于关键词)等方面对土壤环境中ARGs污染相关研究进行剖析,以此探讨国内外该领域的研究现状、热点和发展.结果表明,土壤中ARGs污染相关研究的发文数量快速增长.我国文献在发文数量、论文被引频次方面具有重要影响,表明我国在该领域有较强的国际学术影响力.关键词聚类分析表明该领域的研究方向主要集中在以下5个方面:(1)土壤中携带ARGs的微生物及其环境行为;(2)土壤环境中ARGs的来源和持久性;(3)土壤环境中ARGs的传播和消减方法;(4)土壤中共存物质对ARGs丰度和迁移行为的影响;(5)农业生产活动对土壤环境中ARGs污染的影响.同时,在介绍ARGs常用检测方法以及土壤环境中ARGs污染来源和分布的基础上,剖析影响ARGs在土壤中传播的多种因素,探讨土壤环境中ARGs的消减方法,并指出当前研究尚存的不足之处以及今后的研究方向.该文可为未来土壤环境中ARGs污染领域的研究和风险管控提供参考.
Abstract
In recent years,antibiotic resistance genes(ARGs)in soil environments have attracted widespread attention.A bibliometric analysis was conducted using the Web of Science core database and Wanfang database as data sources to an-alyze the researches on ARGs contamination in soil environments from the aspects of annual publication volume,contribu-tions from different countries,and the evolution of research topics(based on keywords).The aim was to explore the cur-rent status,hotspots,and development trends in this domain both domestically and internationally.The results show a rapid increase in the number of publications annually on ARGs contamination in soil.Chinese literature had a significant impact in terms of publication volume and citation frequency,indicating its strong international academic influence in this field.Keyword clustering analysis revealed that the current researches in this field have been mainly focused on the follow-ing areas:(1)microorganisms carrying ARGs in the soil environments;(2)source and persistence of ARGs in soil envi-ronments;(3)transmission and reduction methods of ARGs in soil environments;(4)the influence of coexisting sub-stances in soil on the abundance and migration behavior of ARGs;(5)the impact of agricultural production activities on ARGs contamination in soil environments.Additionally,commonly used detection methods for ARGs were introduced,the sources and distribution of ARGs contamination in soil environments were also analyzed.Various factors influencing the spread of ARGs were analyzed,and methods for reducing ARGs in soil environments were discussed.Current shortcomings and future research directions in this field have been pointed out.This article can serve as a reference for future research and risk management in the field of ARGs contamination in soil environments.
