[目的/意义]突发事件的发生往往伴随着各类谣言信息的扩散,谣言的传播会对事态的发展产生重大影响,为了研究谣言扩散的规律,更好的预测群体性突发事件的发展局势,以便采取有效措施来降低突发事件对社会的不良影响。[方法/过程]通过对谣言扩散规律的研究,在研究过程中根据群体性突发事件的特点,对基本的BASS模型进行改进,引入核心区域概念,同时对改进的谣言扩散模型进行M ATLAB仿真,分析各个影响因子对区域谣言扩散的影响。[结果/结论]研究结果表明该谣言扩散模型能够有效的反应谣言信息的扩散规律,根据谣言扩散规律得出切实可行的处理建议,为谣言扩散的控制提供了理论依据。
[ Purpose/Significance ] The occurrence of events is often accompanied by the spread of information of all kinds of rumors, and the spread of rumors will have a significant impact on the development of the situation. In order to study the law of the rumors spread, better predict the development of the situation of group incidents, and take effective measures to reduce the adverse impact of the incident on society. [ Method/Process] Through the research on the laws of the rumors spread, according to the characteristics of the mass inci- dents, this study improves the basic BASS model in the process of research, introduces a concept of core region, and at the same time con- ducts a MATLAB simulation for the improved model of the rumor spread, in which each factor' s influence on regional rumors spread is analyzed. [ Result/Conclusion] Research results show that the rumor spread model can effectively reflect the law of rumor spread, then de- tailed operational tactics for handling rumor spread are proposed, providing a theory basis for effective control of the spread of rumors.
