基于VOSviewer的水环境微塑料研究趋势分析

Research trend analysis of micro plastics in waterenvironment based on VOSviewer

为了解水环境微塑料研究现状,厘清微塑料方向的研究热点,以Web of Science收录的核心期刊为数据源,筛选出3 845篇相关论文,利用可视化计量软件VOSviewer并通过文献计量学方法绘制出可视化图谱。结果表明,从时间上看,自2019年该领域研究发文量呈现迅猛上升趋势;从国家研究实力上看,水环境微塑料研究与国家经济实力成正相关;研究主题集中在“微塑料的毒性评估”、“丰度和分布”、“空间运动趋势、降解去除”与“群落影响以及食物链富集”上,微塑料与水环境中的新兴污染物的污染特征及复合效应是当前研究出现的新兴趋势。最后,对未来水环境微塑料研究,提出了建议和展望。

In order to explore the research status,hotspots and research trends of microplastics in the water environment,bibliometric statistics were conducted according to 3845 documents collected from Web of Science core database and analyzed by VOSviewer,which was a visual measurement software.From the perspective of time,the number of research papers in this field has shown a rapid upward trend since 2019.The research on microplastics in the water environment was positively related to national economic strength from the national research strength.The international research hotpots of microplastics were mainly focused on“toxicity assessment”,“abundance and distribution”,“spatial movement trend”,“degradation removal and its impact on communities”and“food chain enrichment”.The emerging trend in current research is the pollution characteristics and combined effects of micro plastics and emerging pollutants in the water environment.Finally,some suggestions and perspectives for future microplastics research were provided.
