基于中文文献分析淡水环境中微塑料研究的发展趋势

Research Trend of Microplastics in Freshwater Environment Based on Chinese Literature Analysis

为充分掌握国内淡水环境中微塑料研究的发展趋势,首次将中文文献经过数据库转换导入文献分析R工具——bibliometrix进行分析。结果表明,国内淡水环境中微塑料的研究处于起步阶段,相关成果逐年增加;这些文章主要集中于核心区期刊上;高产作者和高影响力团队呈现集中趋势,主要分为江西师范大学团队、国家重点实验室合作团队、长江科学院团队和太原理工大学团队;从关键词的共现性上看,这些研究可以分为综述性、特定区域、污水处理、调查评价四种聚类,而从时间趋势上看,这一领域从淡水水体、微塑料丰度扩展到湿地、沉积物等淡水环境,深入到复合污染、毒性效应等关键内容。这些结论为开展淡水环境中微塑料的研究提供了科学的参考依据。

To fully grasp the research trend of microplastics in the freshwater environment,the Chinese literature was transformed into bibliometrix,a literature analysis R tool,for deep analysis for the first time.The results show that the research on microplastics in the freshwater environment in China is in its infancy,and the relevant achievements are increasing.These articles are mainly concentrated in the journals in the core area.The high-yield authors and high influence teams show a centralized trend,which are Jiangxi Normal University team, State Key Laboratory cooperation team, Changjiang Academy of Sciences team and Taiyuan University of Technology team.From the co-occurrence of keywords,these studies can be divided into four clusters:summary,specific area,sewage treatment and investigation and evaluation. From the perspective of trend,the research extends from the freshwater water bodies and microplastic abundance to the freshwater environment such as wetlands and sediment,and goes deep into critical contents such as combined pollution and toxic effect.These conclusions provide a scientific reference for microplastic research in the freshwater environment.
