基于SCI发文的中国生态学研究态势文献计量分析

A bibliometrical analysis of status on ecology research in China based on SCI database

采用文献计量学的方法,基于《科学引文索引》数据库近十年的检索结果,定量分析中国生态学领域发文的主题、时间、作者、机构、合作国家、被引频次、期刊分布等数据,系统分析中国生态学领域近十年的研究发展态势、研究热点、研究投入主体、国际合作和研究水平等趋势和特征。基于检索得到的3316篇SCI论文数据,研究认为:我国生态学领域的研究发展迅速。研究的热点主要是分子标记、气候变化、生物多样性、土地利用、分类学、物种、草原、荒漠化、模型、多态性等方面。研究主题的关联性随时间有增加的趋势。588个第一作者发文机构中,中国科学院发文量最高,大学近年的研究发展迅猛。生态学领域篇均作者人数是2.2人。国际合作的主要国家是美国。我国生态学研究的SCI发文篇均被引频次为6。第一作者机构为中国机构的论文被引用情况逊于外国机构。中国生态学领域研究最重要的发文期刊是ECOLOGICAL MODELLING和JOURNAL OF ARID ENVIRONMENTS。
