摘　　要：为统筹考虑线上社交网络与线下社交网络在舆情传播中的作用,首次提出了一种包含"媒体层-线上层-线下层"的多层同步网络模型,并在此基础上搭建了舆情仿真系统框架.基于对人类社交网络拓扑结构的已有研究成果,给出了多层同步网络的缺省设定.通过案例仿真,分析了线上网络与线下网络之间的相互影响,对比了舆情事件目击者数量在多媒体传播、自媒体传播这两种舆论传播模式中的作用差异.最后,讨论了多层同步网络模型的兼容性与可扩展性,并指出了该模型改进的方向.For considering the role of both online social network and oittine social network in the public opinion transmission, the multilayer synchronization network containing media layer, online layer and offline layer was built. And on this basis, public opinion simulation system framework was set up. Based on the research achievements of predecessors for human social network structure, multi-level synchronous network is given in the default setting. Through case simulation, demonstrated the mutual influence between online and offiine networks and compared the different effect of the number of witness in the self-media communications and multimedia communications in the role of public opinion propagation. In the end, discussed the compatibility and scalability of the multilayer synchronous network model and put forward the improvement and extension direction.
