基于文献计量分析的微塑料研究现状及热点趋势

Research Status and Hot Trends of Microplastics Based on Bibliometric Analysis

微塑料污染已成为与气候变化、臭氧层破坏和海洋酸化等并列的全球环境问题。为了解微塑料的研究进展和未来发展趋势,以中国期刊全文数据库(CNKI)、Web of Science(WOS)为检索源,利用文献计量学方法探究微塑料文献中的内在关联和热点趋势(2004—2020年),利用VOSviewer和COOC共现网络分析与可视化工具对微塑料研究领域的发展动态、研究热点及前沿方向进行分析。通过梳理2004—2020年微塑料文献发表年限分布情况、文献机构分布、文献关键词等内容,系统分析微塑料的研究热点和前沿方向。

Microplastic pollution has become a global environmental problem alongside climate change,ozone layer destruction and ocean acidification.In order to understand the research progress and future development trends of microplastics,the China Journal Full-text Database(CNKI)and Web of Science(WOS)are used as the search source to explore the internal relations and hot trends in the microplastics literature using bibliometric methods(2004-2020),use VOSviewer and COOC co-occurrence network analysis and visualization tools to analyze the development trends,research hotspots and frontier directions in the field of microplastics research.This article systematically analyzes the research hotspots and frontier directions of microplastics by combing through the distribution of microplastics literature publication years,the distribution of literature institutions,and literature keywords from 2004 to 2020.
