摘　　要：随着互联网的迅猛发展,网络谣言正如"病毒"一样在人们的生活中散播。如何有效地消除在人们接收健康信息时谣言带去的阻碍与混淆作用,在现今信息时代已尤为重要。借鉴经典的SIS疾病传播模型和种群竞争模型,探讨官方媒体在谣言传播过程中的影响作用。构建非线性微分方程模型来刻画谣言传播过程,并对方程的平衡点、解的有界性及稳定性进行了分析,最后赋予相关参数一定的数值,利用MATLAB进行模拟仿真,讨论不同情境下的演化机理,得出了官方媒体确实在谣言传播过程中有着积极却又有限的作用这一结论,期望可为应急管理者制定谣言传播控制策略提供支持。With the rapidly development of internet, rumor is dispersing around the people as the ＂virus＂. How to eliminate efficiently the obstacles and confusion role when humans are absorbing healthy information, which is becoming particularly im- portant in today＇ s information era. Based on the classical SIS model of epidemic and competitive model, this paper discussed the impact of authoritative media in the process of rumor spreading. Then, it proposed non-linear differential equation model to describe the rumors spreading; also, it analyzed mathematical analyses of the model equations with regard to equilibria, boundedness of solutions, and stability. Finally, given the value of certain parameters, it presented a discussion of evolutional mechanism under different scenarios with numerical simulation by MATLAB, which came to some conclusions and suggestions for providing theoretical foundation support to formulating strategies that used for controlling the spread of rumors by the emer- gency managers.
