国内气象学领域博士学位论文研究热点揭示

The Revealing of the Hotspots in Doctoral Dissertations of Domestic Meteorology

为更好地服务大气科学"双一流"学科建设,获取气象学知识结构图谱,挖掘气象学研究前沿热点与演进路径,在中国知网博士论文库搜集了气象学领域论文1 466篇,利用CiteSpace软件进行关键词共现分析,利用聚类图分析不同学位授予机构的研究方向,分析了4个时间段(2000-2004年,2005-2009年,2010-2014年,2015年至今)的研究热点,利用时间线视图分析了各主题时间跨度。结果显示,学位授予机构研究热点聚类效果不明显,不同时期研究热点差异大,各主题随年代变迁研究冷热程度变化明显。

In order to better serve the construction of atmospheric science as a"double first-class"discipline,obtain the knowledge structure map of meteorology, and dig the frontier hot spots and evolution path of meteorology research,this paper collectes 1466 papers in the field of meteorology in CNKI doctoral dissertation database,uses Cite Space software to conduct keyword co-occurrence analysis,uses cluster diagram to analyze the research directions of different degree awarding institutions,analyzes the research hotspots in four time periods(2000-2004, 2005-2009, 2010-2014, 2015 to date),and uses timeline view to analyze the time span of each theme. The results show that the clustering effect of research hotspots of degree awarding institutions is not obvious, and the research hotspots vary greatly in different periods, and the research hot and cold degree of each topic changes obviously with the changes of years.
