摘要
为了识别中外在北极环境领域的研究差距,构建先进的北极科考框架,基于CiteSpace工具对国际和国内北极环境领域近30年的文献进行计量。通过共现、聚类和共被引分析发现北极环境研究发展可分为三个阶段;北极八国和德英法在北极环境研究中占据主导地位;北极环境研究与地质学和大气科学等学科密切相关;海冰、冻原、永久冻土和积雪是最热门的北极环境污染物介质,多氯联苯、汞和二氧化碳在污染物研究中占据主导地位;突现性污染物的研究重点变化趋势是氯代烃—臭氧—重金属—黑碳,持久性有机污染物的突现性始终存在;通过国际和国内的研究对比分析发现我国生态毒理学研究的不足。最后,从需要进行监测的污染物、可以运用的理论技术以及需要开展的环境领域科研工作等方面,对我国北极环境研究提出建议。
To identify the Arctic environmental research gap between China and other countries,we built an advanced Arctic scientific research framework based on the CiteSpace tool,a bibliometric tool,to conduct a literature review for nearly 30 years of Chinese and international Arctic environmental research from 1990 to 2020.Through co-occurrence,clustering,and co-citation analysis,we found that the development of Arctic environmental research can be divided into slow development,rapid development and stable development stages,and the eight Arctic countries and Germany,Britain and France are the leaders in Arctic environmental research.We also found that Arctic environmental studies are closely related to the disciplines of geology and atmospheric sciences.Sea ice,tundra,permafrost,and snow cover are the most commonly researched environmental media in the Arctic.There is a recent research trend toward examining pollutants such as chlorinated hydrocarbons,ozone,heavy metals,black carbon,as well as persistent organic pollutants.Comparative analysis of the evolution of Chinese and international research found that international Arctic environmental research over 2010—2020 has focused on polar bears,black carbon,perfluorooctane sulfonate,mercury and microplastics.Chinese research on black carbon,microplastics and perfluorooctane sulfonate closely follows the international trend and takes advantage of the height of the Tibetan Plateau to conduct large-scale climate change research;however,Chinese research has obvious deficiencies regarding ecotoxicology.We conclude by proposing that Chinese researchers place greater emphasis on the pollution of environmental media such as sea ice,tundra,permafrost and snow cover to study the occurrence,form,concentration levels and spatial distributions of pollutants.Such research could use techniques from geology,biology,remote sensing and numerical modeling to identify pollution sources,to obtain particle size distribution information and Arctic biological data,and to analyze the biologica
