全球极端天气研究的情报学分析

Informational Analysis of Global Studies on Extreme Weather

随着全球气候持续变暖,各类极端天气频繁发生,所造成的灾害损失和影响也不断加重,因此,对极端天气的研究成为世界各国学者关注的重要课题。本研究检索了Web ofScience数据库中收录的关于极端天气研究的文献,统计和分析了这些文献的年发表量、文献类型、国家、发文机构、著者、来源、学科类别分布,并确定了高被引作者、高被引出版物和高被引文献,同时对高被引文献进行了共引聚类分析获得该领域的研究热点,从而了解极端天气研究的发展历程,客观反映当前该领域理论与实践研究的现状,并为今后更好的开展极端天气研究提供一定的参考。

As global climate keeps getting wanner, extreme weather occurs frequently, which results in more serious disas- ter and loss. Therefore, study on extreme weather has become an important issue on which the researchers gradually focus in sci- entific field. In this study, the authors collected literatures on extreme weather fi＇om Web of Science. Then, statistical procedure was peffomaed in the following aspects： annual publication number, publication type, countries, institutes, authors, sources, and subject categories. And highly cited authors, publications, and literatures were determined. Moreover, co- citation cluster- ing analysis was performed for the highly cited literatures to explore the hot research topics in this field. By this informational anal- ysis, this paper aimed to discover the status and development in the field of extreme weather and provide the enlightenment and in- formation reference for researchers and decision makers to study better in the field.
