摘　　要：[目的/意义]从Altmetrics视角研究我国科技期刊在社交媒体上的受关注情况、期刊Altmetrics指标的影响因素及其与传统期刊评价指标的关系,以期为合理利用Altmetrics指标评价期刊影响力提供借鉴。[方法/过程]基于《期刊引证报告》(JCR,2017版)和Altmetric Explorer平台,以165种我国科技期刊为研究对象,探讨期刊的Altmetrics指标概况以及学科类别、国际合作水平和开源程度对期刊Altmetrics指标的影响,并通过相关性分析研究期刊Altmetrics指标与影响因子、总被引频次之间的关系。[结果/结论]Altmetric Explorer平台采集的17项Altmetrics指标数据中,期刊的Twitter提及量和覆盖率最高,News、Facebook、Blog和Google+也具有较高的提及量和覆盖率;学科类别、国际合作水平和期刊开源程度对期刊Altmetrics指标均存在影响;Altmetrics指标与传统期刊评价指标呈正的中等程度或弱相关关系;期刊中一少部分论文的高Altmetrics指标值会对期刊整体的Altmetrics指标值产生聚集作用,期刊的Altmetrics指标值并不能全面反映其中每一篇论文的影响力,现有Altmetrics指标体系应用于期刊影响力评价的适用性有待商榷。[Purpose/Significance]From the perspective of Altmetrics,this paper studies the concern about Chinese scientific journals on social media,the influencing factors of Altmetrics and the relationship between Altmetrics and traditional journal evaluation indexes,so as to provide reference for the rational use of Altmetrics to evaluate the influence of journals.[Method/Process]Based on the Journal Citation Report(JCR,2017 edition)and Altmetric Explorer platform,with 165 kinds of Chinese scientific journals as the research object,this paper explored the general situation of Altmetrics of the journals and the impact of discipline category,international cooperation level and open source degree on Altmetrics.Besides,the correlation between Altmetrics,impact factors and total citation frequency was studied through correlation analysis.[Result/Conclusion]Among the 17 Altmetrics data collected by the Altmetric Explorer platform,the mentions and coverage of Twitter are both highest,while News,Facebook,Blog and Google+also have high mentions and coverage.The discipline category,international cooperation level and open source degree of journals all have influence on Altmetrics.Altmetrics has a positively moderate or weak correlation with traditional journal evaluation indexes.The high Altmetrics index value of a small number of papers in a journal has an aggregation effect on the overall Altmetrics index value of the journal.The index value of Altmetrics of a journal cannot fully reflect the influence of each paper in the journal.The applicability of the existing Altmetrics index system in the impact evaluation of the journal remains to be discussed.
