摘　　要：[目的/意义]在互联网普及的21世纪,灵活无序的网络空间成为各种谣言滋生的温床,后真相背景下的谣言传播已成为大众视角下的一个重大问题,通过研究谣言传播的规律,来为降低谣言传播给社会带来的显性和隐性负面影响提出相关建议。[方法/过程]在经典SIR谣言传播模型的基础上,增加了观望者和辟谣者的角色,并将移出者分为中立者、相信谣言者和得知真相者三类,构建了一个改进的WT-SIR*谣言传播模型,并在小世界网络的背景下,采用真实调研数据进行仿真分析。[结果/结论]研究结果表明,小世界网络中,谣言传播的规律与谣言和辟谣信息的性质息息相关,在此基础上,有针对性地提出了一些与谣言传播相关的事前预防和事中控制的建议。[Purpose/Significance]In the 21 st century, as the popularity of the Internet and the rise of post-truth, rumor spreading in the cyberspace has become a serious and complicated social problem in the mass perspective. This paper is devoted to putting forward relevant suggestions about how to reduce the explicit and implicit negative effects of rumor spreading on society through studying its propagation principle.[Method/Process]This paper established an improved WT-SIR* rumor propagation model based on the classical SIR model. The WT-SIR* model added the roles of watcher and truth carrier, and divided the removal into three categories: neutrality removal, removal with rumor and removal with truth. Then the author carried out simulation analysis with the data investigated from the real world based on small world networks.[Result/Conclusion]The results showed that the law of rumor spreading in small-world networks is closely related to the nature of rumor and rumor refutation information. On this basis, the author put forward some suggestions on the prevention and control of rumor spreading.
