    摘要:

    生物修复作为经济有效、绿色可持续的修复技术,在有机污染土壤和地下水修复上具有广阔的应用前景。基于Web of Science核心数据库,通过文献计量可视化应用软件VOSviewer和CiteSpace,分析了1990–2020年有机污染土壤和地下水生物修复领域的研究热点及趋势。结果表明,有机污染土壤和地下水生物修复领域的论文发表数量呈增长趋势,发文总量最多的国家是美国和中国,但是2012年后中国年发文量快速增加,并位居第一。该领域的相关研究主要发表在Chemosphere、Environmental Science & Technology、Science of the Total Environment等top期刊上。全球研究机构中中国科学院发文量最多,但是来自美国加州大学的总被引频次和h-index最高。发文量最多的是来自英国兰卡斯特大学的学者Semple教授,我国发文量最多的是来自中国科学院南京土壤研究所的骆永明研究员。下一步研究重点和热点:针对复合污染土壤和地下水,研发新型耦合强化生物修复技术,采用先进的分子生物学方法探索功能微生物及其功能基因,阐明生物降解机理,明确原位污染土壤和地下水的靶向性调控机制。

    Abstract:

    Bioremediation is regarded as one of the most promising methods for the remediation of the soil and groundwater contaminated with organic compounds, mainly due to its cost-effectiveness and environmental friendliness. Using VOSviewer and CiteSpace, we analyzed all publications in this area in core database of Web of Science from 1990 to 2020. The number of publications in this area showed an increasing trend worldwide. The country with the largest total number of publications was USA, followed by China and India. Since 2012, the number of annual publications of China exceeded USA and ranked the first. The top three journals which published papers in this area were Chemosphere, Environmental Science & Technology, and Science of the Total Environment. The Chinese Academy of Sciences published the largest number of papers among the research institutions globally, but the University of California in USA had the highest total citations and h-index. Bibliometric analysis indicated that it is important to develop biotechnologies of bioremediation coupled with chemical/physical remediation to overcome the challenge of low efficiency and long remediation duration associated with bioremediation. In addition, the bioremediation on the mixed contaminants, such as organic contaminants and heavy metals, or mixtures of different organic contaminants, is an important direction. Finally, the rapid development of microbiome technologies will further promote the exploration of mechanisms involved in bioremediation on the genetic and molecular level.
