摘要：随着科技的不断进步，传统的报刊、广播电视等逐渐被互联网、大数据取代。自媒体也打破了被动接受信息的局面。民众也可以作为“媒体”发声，这一媒介生态环境的改变也使得舆论形成了新的格局。本文通过对微博舆情的分布形态、生成机制和传播过程的研究，重点分析在微博这个零门槛的平台内，当民众作为“媒体”时对突发事件舆论场产生的影响，以及突发事件的微博舆论在引导过程中出现的问题。在此基础上，分析和概括微博的发展给舆论引导带来的新挑战，并以长江沉船事件为例，利用时间序列分析方法分析事件的舆情发展进程，并提出突发事件舆情传播时出现的负面影响及处理建议。我国社会民主化进程的不断推进，言论自由度不断开放，积极正面的言论可以营造良好的社会风气，反之，负面言论和虚假信息会影响社会安定。经过分析找到如何能够避免在舆情传播中产生舆情危机，这是本文所研究的意义。
