Abstract: This article collects citations from China National Knowledge Infrastructure (CNKI) on the topic of "altmetrics", then uses CiteSpace to analyze these citations with visual analysis methods such as key words clustering, authors clustering, authors cooperation network, etc. Analysis results indicate that these researches mainly focus on altmetrics, scholar impact, scientific evaluation, relative analysis and social network. The results also reveal the lack of theoretical innovation and less collaborative research. It is suggested that these two aspects should be further strengthened.

Key words: altmetrics, visual analysis, key words clustering, authors clustering, CiteSpace
