2008年以来国际磷石膏主题的研究热点及趋势演进——基于文献计量和知识图谱的方法

International research hotspot and trend evolution of phosphogypsum since 2008:Method based on bibliometrics and knowledge graph

为明确磷石膏资源化和无害化研究现状及未来发展,采用文献计量学方法统计分析了Web of Science(WoS)数据库中2008-2024年发表的的文献资料,并对年度发文量、机构、期刊、作者和论文关键词等信息单元进行了分析.结果表明:WoS数据库中磷石膏方面的论文共2892篇,年度发文量呈上升趋势;中国、西班牙、美国为发文量排名前三的国家;共计409所研究机构参与磷石膏研究,其中大学和研究中心为主要研究基地,而大学教师和硕博研究生以及研究员为研究主力,发文量最多的是维尔瓦大学的BOLIVAR J P.关键词分析表明:磷石膏主要可以作为水泥、混凝土等建筑材料,其次是对土壤和水进行重金属去除和钝化,其中建筑材料是磷石膏的研究热点.通过突现分析得出,用磷石膏制备建筑材料和用于肥料行业将成为未来的热点方向.

In order to clarify the current status and future development of harmless phosphogypsum resource utilization,bibliometric methods are used to statistically analyze the literature published in the Web of Science(WoS)database from 2008 to 2024.The indices ranging from the number of annual publications,the associated institutions,journals,authors,and the keywords of papers are analyzed.The results show that there are 2892 papers on phosphogypsum in WoS database,and the annual number of publications is on the rise;China,Spain,and the United States are the top three countries in the number of publications;a total of 409 research institutes are involved in the research of phosphogypsum,among which universities and research centers are the main research bases,and university teachers,master and doctoral degree holders,as well as researchers are the main force of the research,and the one with the most publications is BOLIVAR J P from the University of Vilva.Keyword analysis shows that phosphogypsum can be used as building materials such as cement,concrete,etc.,followed by heavy metal removal and passivation for soil and water,among which building materials are the research hotspot.Through the emergence analysis,it is concluded that the application of phosphogypsum in building and fertilizer industry will become the hotspot in the future.
