环境中土壤微塑料研究热点及趋势可视化研究

为探究微塑料的研究现状、热点及趋势,以Web of Science核心合集数据库及中国知网(CNKI)数据库为数据来源,利用CiteSpace等软件绘制作者及机构共现网络图谱、区域分布特征图谱、关键词共现网络图谱和参考文献共被引图谱等,对环境微塑料尤其是土壤微塑料的研究现状及热点进行可视化分析。结果表明:微塑料研究自2016年开始逐步加强,其中土壤微塑料的研究热度在2021—2022年迅速上升;对于土壤微塑料,丰度分布、污染机制和健康风险等是当前研究的热点;完善土壤微塑料检测方法体系,探寻合适的土壤微塑料污染治理和管控方法及对策,对于维护生态安全和保障人体健康具有重要意义。

Visualization of Research Hotspots and Trends on Soil Microplastics in the Environment

In order to explore the current status,hot spots and research trends of microplastics,using Web of Science core Collection database and CNKI database as data sources,this paper used CiteSpace and other software to draw co-occurrence network maps of authors and institutions,regional distribution characteristics,keywords co-occurrence network maps and references co-citation maps.In particular,the research status and hot spots of soil microplastics were visualized.The results showed that the research on microplastics has gradually increased since 2016,and the research on soil microplastics has increased rapidly in 2021 and 2022;the research on soil microplastics,its abundance distribution,pollution mechanism and health risk are the current hot spots;it is important for ecological safety and human health to improve the detection method system of soil microplastics and explore the suitable control methods and pollution control measures.
