环境微塑料污染研究热点与前沿——基于VOSviewer和CiteSpace的数据可视化分析

Research Hotspot and Frontier of Environmental Microplastics Pollution Based on Data Visualization Analysis of VOSviewer and CiteSpace

为了解近年来环境微塑料污染研究的热点、前沿及未来的研究方向,以WebofScience(WOS)和中国知网(CNKI)为信息源,基于VOSviewer和CiteSpace的知识图谱可视化功能,分析了2000—2020年环境微塑料污染领域发表的研究成果。结果表明:近年来发文量随着年份增加呈显著增长;微塑料、海洋环境、区域污染状况、微塑料的影响、监测、生物摄入累积、微塑料溯源、土壤与淡水等主题词为热点研究方向;研究前沿包括淡水、塑料制品、海洋污染、海洋垃圾与海洋生物效应等方面的内容。海洋、淡水等水体当中微塑料污染现状;环境微塑料污染的来源与分布监测;生物体微塑料累积与生物毒性效应;微塑料在食物链、生态系统中的传递富集与生态效应及危害等是未来环境微塑料污染研究的重点方向。

In order to understand the hotspots,frontiers and future research directions of environmental microplastics pollution in recent years,the related research results published on Web of science(WOS) and CNKI from 2000 to 2020 were analyzed based on VOSviewer and CiteSpace visualization of knowledge graphs.The analysis shows that the number of related articles published in recent years increases significantly.Microplastics,Marine environment,regional pollution status,the impact of microplastics,monitoring,biological ingestion and accumulation,microplastics traceability,soil and fresh water,etc.become key words of the research.Research frontiers include freshwater,plastics,Marine pollution,Marine debris and Marine biological effects.The key research directions of environmental microplastics pollution in the future include:current situation of microplastics pollution in Marine,freshwater and other water bodies,monitoring the source and distribution of environmental microplastics pollution,accumulation and toxicity of microplastics in living organisms,the transfer enrichment and ecological effects and harms of microplastics in food chain and ecosystem.
