全球北极底栖生物研究文献计量分析

以Thomson Reuters的Web of Science信息平台提供的SCI-E数据库为数据源,检索到从1991年至2012年期间全球北极底栖生物研究论文2127篇,利用Note Express软件,分析22年间论文发表的年度、国家、机构、作者、期刊和学科等方面的分布特征,结果表明:1)全球北极底栖生物研究论文数量、篇均作者数和篇均参考文献数都在逐年增加;2)研究论文涉及58个国家或地区,位于前7位的国家依次是美国、德国、加拿大、挪威、俄罗斯、英国和丹麦;美国、加拿大、挪威和丹麦是该领域国际合作研究最主要的国家;3)论文涉及1364个机构,前20名的研究机构中,美国有6家,德国、加拿大和挪威各有3家,俄罗斯和丹麦各有2家,波兰有1家。俄罗斯、丹麦、波兰、德国和挪威超过60%的研究力量集中在位列前20位的相关机构中。俄罗斯科学院论文总量排列首位,德国阿尔弗雷德魏格纳极地与海洋研究中心和基尔大学论文的h指数最高为32;4)论文涉及最多的4个学科是海洋与淡水生物学、生态学、海洋学和多学科地球科学。Polar Biology和Marine Ecology Progress Series是发表该领域最核心的期刊。还对中国在该领域的研究现状进行了简要的分析。从文献计量学角度揭示了全球北极底栖生物研究现状,为提升我国该领域研究的国际竞争力提供科学参考。

A bibliometric study of the arctic benthos in world

Bibliometric methods is a common research tool for systematic analysis in various fields. An effective bibliometric analysis based on the Science Citation Index Expanded (SCI-E) published by Thomson Reuters was carried out to provide insights into research activities on arctic benthos from 1991 to 2012. Analyzed aspects included document type, language, and publication output as well as distribution of journals, subject category, countries and institutes. Results showed that 1) Number of papers, author number per article and cited reference count per article on arctic benthos increased year by year. 2) Papers on arctic benthos were published by authors from 58 countries or territories. In the top most productive 20 countries, there were eight member states of the Arctic Council (Russia, Canada, the United States of America (USA), Norway, Denmark, Iceland, Sweden and Finland), as well as nine observer states of the Arctic Council (France, Germany, the Netherlands, Poland, Spain and the United Kingdom (UK), China, Japan and Italy). In the top most productive 20 countries, USA, Germany, Canada, Norway, Russia, UK and Denmark took the top seven positions on many indicators, such as, total article output, single-country independent articles, international collaborative articles, first author publications and corresponding author publications. USA, Norway, Canada and Denmark are the most important international collaborative research nations in the field of arctic research. The USA always took a significantly leading position. 3) There were 1364 institutes contributing to 2127 articles. Out of the 1364 institutes, 1212 institutes produced only 1-5 articles. USA had the 6 most productive institutes on the list of the top 20 most productive institutes. Germany, Canada and Norway each had 3 most productive institutes on the list. Russia and Denmark had 2 and Poland had one. The Russian Academy of Sciences took the first position according to total number of articles (9.4%). However, average citations per item was near the bottom on the list (18^th), and the h-index ranked 10^th. Alfred Wegener Institute for Polar and Marine Research (Germany) and Kiel University (Germany) ranked the highest in the h-index. 4) The top four subjects with the most papers on arctic benthos are marine and freshwater biology, environmental ecology, oceanography, and geology respectively. According to the number of published articles, Polar Biology ranked the first with 165 published articles, followed by Marine Ecology Progress Series (138) which ranked the first based on an h-index of 34. The status of current research related to arctic benthos in China was briefly discussed. The purpose of this study is to quantitatively analyze the literature on arctic benthos and weigh the influence of different countries in arctic studies. It can hopefully facilitate future research on arctic benthos for Chinese scholars.
