摘　　要：基于改进的SIR模型构建了考虑自媒体作为信息传播者的网络谣言传播模型.对其系统稳定性进行数值分析,并通过仿真分析结合实际案例数据验证.仿真结果表明,自媒体的参与将扩大谣言的范围和影响力.在此基础上,提出网络舆情政府控制策略及发布时间点,以有效抑制网络谣言传播、控制舆情.Based on the improved SIR model,a network rumor spreading model was constructed that considers self-media as an information disseminator.The stability of the system was analyzed numerically and verified by simulation analysis combined with actual case data.The simulation results show that the participation of self-media will expand the scope and influence of rumors.On this basis,a government control strategy and release time point for online public opinion were proposed to effectively suppress the spread of online rumors and control public opinion.
