基于Cite Space文献计量的西藏地区重金属研究现状可视化分析

Visualization Analysis of Research Status on Heavy Metalsin Xizang Based on Cite Space Bibliometric Analysis

重金属污染是生态环境问题之一,西藏是我国重要的生态安全屏障,对西藏生态环境的保护和重金属污染防治极其重要。基于Cite Space文献计量法,利用CNKI数据库,以西藏重金属为主题,归纳了2006年至2022年相关文献的发文量、核心作者、主要研究机构、关键词等,对其研究现状、研究热点及发展趋势进行可视化分析。结果表明,发文量整体呈上升趋势;该研究领域的核心作者为6名,核心作者的总发文量未达到该领域总论文数的50%,未形成核心作者群;发文机构主要以西藏大学、西藏农牧学院等高校为主;关键词的共现、聚类、时序分析得出西藏地区重金属的研究主要集中在产品及环境重金属的含量与形态测定、来源解析、重金属水平评价与生态风险评估。结合以上分析,为科研人员后续研究提供了参考及建议。

Heavy metal pollution is one of the ecological environmental issues,and Xizang serves as an important ecological security barrier in China.Therefore,the protection of Xizang s ecological environment and the prevention and control of heavy metal pollution are extremely important.This paper utilizes the CiteSpace bibliometric analysis method and the CNKI database to focus on heavy metals in Xizang.It summarizes the publication volume,core authors,main research institutions,and keywords of relevant literature from 2006 to 2022,and conducts a visualization analysis of the research status,hotspots,and development trends.The results show that the publication volume exhibits an overall increasing trend.The core authors in this research field consist of six individuals,but their total publication volume does not reach 50%of the total number of papers in this field,indicating the absence of a core author group.The publishing institutions are mainly represented by Tibet University and Tibet Academy of Agriculture and Animal Husbandry.The co-occurrence,clustering,and temporal analysis of keywords reveal that research on heavy metals in the Xizang region primarily focuses on the determination of content and forms of heavy metals in products and the environment,source analysis,and the assessment of heavy metal levels and ecological risks.Based on the above analysis,reference suggestions are provided for subsequent research by scientific researchers.
