为了解国内外污染场地相关研究状况，利用知识图谱工具VOSviewer、CiteSpace与HistCite对Web of Science核心合集数据库中发文的主要国家（地区）与机构、主要发文期刊、主要研究学者、重要文献和研究热点及其变化趋势等进行了计量分析。结果表明：（1）污染场地的研究涉及多个国家之间相互合作，发文机构中中国科学院、橡树岭国家实验室、滑铁卢大学、中国科学院大学与亥姆霍兹环境研究中心在该研究领域合作广泛。中国于近五年发文量超过美国，成为该领域发文最多的国家。（2）污染场地研究的主要发文期刊有Science of the Total Environment、Chemosphere、Environmental Science&Technology、Environmental Science and Pollution Research等，Naidu Ravi、Huang Guohe、Megharaj Mallavarapu等是该领域发文较多的研究学者。污染场地前十（TOP 10）的重要文献中，生物修复相关内容中占据了较高比例。（3）关键词聚类网络主要可分为污染场地生物毒理研究、土壤重金属及修复技术、污染物环境行为及水体修复、有机污染物生物修复等4类。（4）文献计量的结果分析表明土壤与地下水均为污染场地有害物质重要承载体，污染场地中土壤和地下水具有一体性，如果忽视了对地下水中污染的修复，则可能会导致场地的二次污染。重金属与多环芳烃是污染场地重点关注的污染物，我国目前重金属污染防治工作依然不容乐观，需要进一步加强和落实相应工作。寻求高效绿色的修复技术仍是解决污染场地问题的一个重点，提升微生物修复技术在有机污染场地修复中的应用价值，具有重要意义。
[Objective] Contaminated sites have become a serious environmental problem in China. It is particularly important to safely reclaim and utilize the contaminated sites. In order to make clear status of the current researches on contaminated sites, bibliometric analysis was performed. [Method] Knowledge graph analysis tools, like VOSviewer, CiteSpace and HistCite, were used in the bibliometric analysis of countries, institutions, journals, first authors and hot spots of the publications and important papers contained in the core collection database of the Web of Science.[Result] Results show: (1) The research on contaminated sites involves cooperations between multiple countries. In the past five years, China has come out to be the country with the largest number of papers in this field, and in close cooperation with many countries. Paper contributing institutions in this field, like the Chinese Academy of Sciences, the Oak Ridge National Laboratory, the University of Waterloo, the University of Chinese Academy of Sciences and the Helmholtz Environmental Research Center, have been cooperating extensively; (2) The Science of the Total Environment, Chemosphere, Environmental Science & Technology, Environment Science and Pollution Research, etc. are the main journals publishing papers in this field, and Naidu Ravi, Huang Guohe, and Megharaj Mallavarapu are on top of the list of highly productive scholars. Among the top 10 important papers on contaminated sites, bioremediation-related content occupies a quite high proportion; (3) In the keyword clustering network, key words of papers were sorted into four clusters: biological toxicology research on the contaminated sites, soil heavy-metals contamination and remediation technologies, pollutants environmental behavior and water remediation, and bioremediation of organic pollutants contaminated sites; (4) The bibliometric analysis shows that soil and groundwater are important pollutants carriers in the contaminated site. Remediation of the soil and groundwater in the contaminated site should deem the two as one. The neglect of either one in remediation may cause secondary pollution in the contaminated site. Heavy metals and polycyclic aromatic hydrocarbons are the pollutants of great concerns. Searching of efficient and green remediation technologies are still the focus of future work in the contaminated site research field. [Conclusion] It is still not optimistic for China to address the issue of remedying heavy metals contaminated sites, which calls for further efforts to intensify and implement corresponding works. Therefor it remains to be a focus in solving the problem of contaminated sites to explore high-efficiency green remediation technologies and it will be of great application value to improve the application of bioremediation technology to remedying contaminated sites.
