基于CiteSpace分析的突发性环境污染应急技术研究进展

梳理我国环境污染应急处理技术领域的研究进展，对我国突发环境事件应急的技术创新和科学管理具有重要意义。以1995—2020年中国知网数据库为数据源，基于文献计量学分析方法，应用CiteSpace软件对文献特征、研究热点和研究趋势等进行可视化研究。结果表明：我国环境污染应急处理技术领域起步较晚，文献数量不多，研究基础较薄弱，领军人物和核心研究团队还比较缺乏；应急处理技术主要集中在水环境领域，聚类分析发现，应急处理技术研究主要围绕应急监测、技术筛选、活性炭吸附、混凝沉淀等方面开展，关键词聚类时间线显示，未来发展的方向主要是技术筛选、活性炭吸附和应急监测等。

Research progress of emergency technology for sudden environmental pollution based on CiteSpace analysis

It is of great significance for the technical innovation and scientific management to sort out the research progress in the field of emergency treatment technologies for environmental pollution in China. To analyze the research progress of emergency treatment technologies for environmental emergencies, the relevant literature collected in CNKI database from 1995 to 2020 was used as the data source and CiteSpace software was applied to visualize the literature characteristics, hot topics and research trends based on the bibliometric analysis method. The results showed that the field of environmental pollution emergency treatment technologies in China started late, the number of literature was small, the research foundation was relatively weak and there was still a lack of strong leaders and core research teams. The emergency treatment technologies were mainly concentrated in the field of water environment. The keyword cluster analysis found that the emergency treatment technology researches mainly focused on emergency monitoring, technology screening, activated carbon adsorption, coagulation precipitation and other aspects. The keyword clustering timeline showed that the future development directions should be mainly technology screening, activated carbon adsorption, emergency monitoring and so on.
