社交媒体的兴起和发展正在变革着诸多领域。近年来，世界范围内灾害事件的频发也使得学界对灾害事件中社交媒体予以了高度重视。采用内容分析法对SSCI数据库中的相关研究文献进行多角度分析，呈现出当前研究的主要特点。这些特点包括：灾害社交媒体研究的交叉学科属性，引发了学界的广泛关注；所发期刊分布非常分散，研究者更倾向于合作而非独作；文献的被引频次表现较好。内容分析还涉及研究主题、内容、理论和方法等方面。最后，指出了现有文献在社交媒体平台和研究人员国别背景方面可能存在的偏见，并探讨了未来相关研究的方向。%The rise of social media has influenced every walks of life as well as academic research. Recently, a special attention is paid on disaster social media. This paper adopts content analysis of several aspects of related literature in SSCI database, and presents a comprehen-sive understanding of current research. The research is an interdisciplinary study in nature and attracts various academic interests. Scholars prefer to cooperate in this field than alone. Their publications also suggest a high citation rate. A further exploration of research topic, con-tent, theory and method are conducted. This paper concludes that an obvious research bias is discovered in the English-language based so-cial media use. Future research may focus more on cross-culture study, and become more diverse in its nature as social media technology emerges.
