摘    要:运用文献计量学的研究方法,以Web of Science(WoS)为数据源,利用Excel软件对1990—2015年发表的相关PM_(2.5)研究的文献进行数据统计与分析,从文献发表年代、主要发文国家/地区、研究机构、期刊分布、热点文献等方面采用定量、定性的方法揭示了目前世界PM_(2.5)的研究进展。结果表明,近10年关于PM_(2.5)研究发文量增长较快,PM_(2.5)研究全球关注度较高,美国无论发文量、总被引频次和H指数都远超过其他国家/地区,体现了美国在PM_(2.5)研究领域的主导地位;PM_(2.5)相关领域的研究机构主要集中在美国和中国(未包含港、澳、台地区数据);文献多发表在相关大气化学与物理学、环境、健康、气溶胶等领域的刊物上;当前研究热点由PM_(2.5)所引发全球关注的生态环境问题转入对人体健康的影响上,且国际合作研究成为发展趋势。中国自2006年以来PM_(2.5)的研究文献增速显著,发文量和累计被引频次位居世界第二,仅低于美国。

关 键 词:PM2.5  文献计量学  定量分析

Abstract:This paper made a statistical analysis on the literatures of PM2.5 published from 1990 to 2015 by Excel software and Bibliometrics based on Web of Science database, quantitatively and qualitatively revealed the present research progress of PM2.5 in the world in the aspects of publication years, main countries/regions, research institutions, distribution of periodicals, hot subjects, etc.,. The results showed that the complex and diverse languages and literature type is the characteristic of PM2.5 literatures, display global higher attention, especially literatures in recent 10 years were identified rapid growth; the United States regardless of the number, total cited frequency and H index are far more than any other country, which reflects its dominant position and obvious advantage in the field of PM2.5 research. The related research institutions are mainly concentrated in the United States and China; the literatures are mainly published on journals about atmospheric chemistry and physics, environmental, health, aerosol. The current hot global attention research caused by PM2.5 is shifting from the ecological environment problems to impacts on human health, and the research development trend becomes international cooperation. Since 2006, the study of PM2.5 in China has grown significantly, same with the world level. The total published papers and the cumulative citation rates are the No.2 in the world, but the overall level of paper quality is lower than the United States and other developed countries. So, the paper influence remains to be improved in future.
Keywords:PM2.5  bibliometrics  quantitative analysis
