摘　　要：[目的/意义]随着新媒体的迅猛发展,微博等在线社交网络上的谣言传播已被学者广泛关注,但针对微信谣言传播的研究尚不多见。[方法/过程]考虑到微信谣言传播的新特性,将公众用户从微信个人用户传播网络中分离出来,构建微信谣言传播两层网络。区分两层网络谣言转发阈值差异、借鉴社会加强和兴趣衰减理论,建立了新的两层网络谣言传播模型。通过仿真实验,利用Multi-Agent仿真平台Netlogo研究了谣言在新模型中的演化进程,分析了谣言转发阈值、谣言和真相转发兴趣值以及公众用户理性传播系数的变化对谣言传播的影响。[结果/结论]研究发现提高谣言转发阈值、降低谣言转发兴趣值、增加真相转发兴趣值、规范公众用户从业道德有利于抑制谣言的传播。[ Purpose/Significance ] With the rapid development of new media, the rumor spread on micro-blog and other online social networks have been widely concerned, but the research on rumor spread of WeChat is still rare. [ Method/Process ] Separating official accounts from the personal user communication network, a two-layer rumor spreading model of WeChat has been constructed. Considering the difference between the two layers of network rumors forwarding threshold, drawing on the theory of social reinforcement and interest attenuation, a new two-layer network rumor propagation model is established. In the simulation experiment, using a Multi-Agent simulation platform Netlogo, the evolution of rumor spread on the new model has been studied. [ Result/Conclusion] We found that it is conducive to curb rumors spreading by improving the rumor forwarding threshold, decreasing the rumor forwarding interest value, increasing the truth forwarding interest value and regulating official accounts＇ business ethics.
