摘　　要：利用中国知网引文数据库,以理、工、农、医、人文、经济、社会科学大类中3门学科在2011—2015年核心期刊的下载频次和被引频次为基础,通过构建期刊下载和被引的H指数、复合H指数等指标,分析不同学科期刊2011—2015年下载频次和被引频次复合H指数的相关性系数变化情况及其原因。结果发现,2011—2015年理、工、农、医类期刊下载频次与被引频次的相关性高于经济、人文、社会科学类期刊;除文学及临床医学学科外,理、工、农、经济、社会科学同一大类中学科间的复合H指数间相关性系数大小可以互相推测,但是各年相关性变化情况不一致;在期刊评价中,不同时间、不同学科下载频次和被引频次需赋予不同权重。The research is using the CNKI and is based on the citations and the number of downloads of the 2011-2015 core journals of the three disciplines of the science,engineering,agriculture,humanities,economics and social sciences.Then the research builds the journal’s download and cited H-index,compound H-index and other indicators.The research is aim to analyse the relationship and trends between compound H-index of different journals in different disciplines from 2011 to 2015.It is found that the correlation between the numbers of downloads and citations of science,technology,agricultural and medicine journals in 2011-2015 is higher than that of economic humanities and social science journals.In addition to literature and clinical medicine,the correlation of compound H-index between disciplines in the same category of science,industry,agriculture,economics and social science can be inferred from each other,but the correlation changes in different years are inconsistent.When evaluating journals,the frequency of downloads and citations of different subjects are different at different times.
