基于文献计量的重金属固化稳定化修复技术发展动态研究

为了解国内外场地土壤和底泥的重金属固化稳定化技术(S/S)的发展状况、研究热点及发展趋势,通过CNK《I中国期刊全文数据库》和WebofScienceTM核心合集数据库对20062018年间发表的关于污染场地重金属固化稳定化修复技术的文献进行检索,并利用Excel2016、HistCitePro2.1引文图谱分析软件和Origin9.0作图软件,从年度发文量、主要发文国家/地区、期刊来源、Top10高被引论文、Top10研究机构、研究内容、修复材料类型、重金属类型等方面,对20062018年发表的有关文献进行计量分析。结果表明:近13年来,中英文文章及专利的发文量逐年升高,且中文发文量远高于英文。英文文章中,中国作者、中国科研机构发文量均居首位,但总均篇被引次数(TGCS/R)较低;Top10高被引论文中,中国作者占据2篇。中英文文章中,对复合修复材料的研究较多,其中常见的复合修复材料为生物质炭、石灰、沸石、硅藻土等材料中的2种或2种以上复合而成,最受关注的重金属污染物为镉和铅,对固化/稳定化设备和工艺的研究较少。因此,对固化稳定化技术的研究,中国研究人员虽然发文量占据较大的比例,但还需进一步提高研究的国际影响力,加强对稳定化修复工艺、设备和效果评价方法的研究。

Bibliometrics-based development trends of solidification/stabilization technology for the remediation of sites contaminated by heavy metals

To fully understand the state-of-the-art and trends of solidification/stabilization(S/S)technology for the remediation of sites contaminated by heavy metals, literatures from the China National Knowledge Infrastructure(CNKI), China Academic Journals Full-text Database, and Web of Science Core Collection Database published from 2006 to 2018 were investigated. The collected documents were screened and sorted using Excel 2016, HistCite Pro 2.1, and Origin 9.0. Annually published papers, the country/region of origin, published journals, the top ten cited papers, the top ten research institutions, research content, remediation materials, and contaminants were all factors that were analyzed and compared. The following conclusions were drawn:The number of Chinese publications increased over the 13 studied years and significantly more studies were published in Chinese than in English. In addition, the number of English publications from Chinese authors and research institutions were more than those from other countries; however, the average total global citation score (TGCS/R)of them was relatively low. Among the top 10 most cited papers, only two were by Chinese authors. Furthermore, although much research was focused on combined remediation materials derived from biomass carbon, lime, zeolite, diatomite, etc., few led to the development of equipment and technical implementation processes. The most studied contaminants were found to be cadmium and lead. In the future, Chinese scholars should reference international research results more to improve the quality of their work and ensure it has greater influence. Additionally, advances should be made in technical processes, the treatment of equipment, and standardized post evaluation methods.
