摘要: 本文以“社交媒体多层次信息流”为概念框架，分析了四川九寨沟7.0级地震发生后，个人、当地的组织、宏观层面的主流媒体使用社交媒体所发挥的作用。通过对微博的数据进行挖掘分析，总结出地震灾害发生后社交媒体所具有的5项功能：人际之间的交流，地方政府、本土组织以及当地媒体的传播渠道，大众传媒信息发布的渠道，信息的收集和分享，微观、中观以及宏观各主体间沟通的渠道。在强震发生后社交媒体有巨大的传播潜力，本文的研究成果对未来大震发生后如何利用社交媒体来应对灾害有一定的借鉴意义。Abstract: Based on the "social media multi-level flow" as the conceptual framework, we analyzed the roles of the mainstream media, individual local organizations, the macro level in social media after the Jiuzhaigou MS7.0 earthquake.
