基于CiteSpace的核素扩散迁移问题的研究发展趋势分析

Analysis of the Development Trend of the Research on the Problem of Nuclide Diffusion and Migration based on CiteSpace

为探索放射性核素在环境中迁移扩散的研究热点与发展趋势,以CNKI上2001~2020年的相关文献为基础,应用CiteSpace软件进行文献计量处理,从作者合作、机构发文情况、关键词共现与聚类分析和关键词突现等方面对国内核素扩散迁移问题的科研力量、研究热点、发展趋势和研究前沿进行分析。结果表明:核素扩散迁移领域的研究成果形式主要是学术论文和学位论文;中国辐射防护研究院、东华理工大学、成都理工大学的研究成果较多;作者写文章的合作比较分散,形成的典型合作研究集团不多;在核素扩散迁移研究领域内的研究热点主要为扩散迁移情况模拟和放射性废物处理两方面,研究从早期的土壤水体中核素向大气中核素进行转变。

In order to explore the research hotspots and development trends of the migration and diffusion of radionuclides in the environment based on the relevant literature on CNKI in the past 20 years from 2001 to 2020, the CiteSpace visualization software is used for bibliometric processing. Based on the author cooperation、institution dispatch、keyword co-occurrence, cluster analysis, and keyword emergence, analyses is conducted on the scientific research strength, research hotspots, development trends and research frontiers of the domestic nuclide diffusion and migration issues. The results show that the research outputs in the field of nuclide diffusion and migration are mainly academic papers and dissertations;the China Institute of Radiation Protection, East China University of Technology, and Chengdu University of Technology have more research results;collaboration among authors in writing articles is diffuse, few typical cooperative research groups have been formed;the research hotspots in the field of nuclide diffusion and migration research are mainly two aspects: on the one hand, diffusion and migration simulation,on the other hand, radioactive waste treatment, studies on the nuclides will involve a transition from objects in early soil or water to those in the atmosphere.
