摘　　要：[目的/意义]舆论引导是媒体宣传工作的重要组成部分,但在复杂的网络舆论环境中,以散乱自由信息为主的环境噪声,往往会对舆论观点的引导过程产生干扰。[方法/过程]为了揭示噪声干扰下的网络舆论观点引导机理,首先对微博媒体和环境噪声进行特征分析,并在此基础上构建噪声干扰下的网络舆论观点引导模型,最后通过仿真实验研究媒体引导、噪声干扰以及二者协同作用对舆论观点演化的影响差异。[结果/结论]实验结果表明,媒体对舆论观点演化的引导过程有显著效果;噪声不仅会干扰节点间的观点交互,还会影响媒体对舆论的引导过程,弱化媒体引导作用。[Purpose/Significance] It is an important part for propagate of medium to guide public opinion. While in complex network en- vironment, mixed messages, the main source of environmental noises, will interfere with the guidance of Interact public opinion. [ Method/Process] In order to study the guidance of Interact public opinion under the noise interference, we first analyze the characteristics of microblogging medium and environmental noises, then propose a model of public opinion guidance under noise interference, and at last study the different influence on public opinion evolution of the media, noise interference and the coordination of them via computer simulations. [Resnit/Conelusion] The simulations＂ results show that media have important influence on the guidance of Interact public opinion evolution; noises not only interfere with the opinion interaction among nodes, but also affect the process of media guidance, weakening the guidance.
