Since the arrival of the Web2.0 era, network media become a key approach of public crisis and risk transmission. In this context, the formation and evolution of public opinion crisis is a serious problem nowadays, which attracts much more attention from the whole society. Therefore, spread mechanism of network public opinion crisis is choosed as the research object. After collecting and sorting 20 public opinion crisis incidents in recent years, the basic concepts, expression forms, driving factors, and specific patterns of public opinion spread are systematically summarized. Then, the spread and diffusion model of network public opinion is built, which completely considers the internal and external impact factors of spread mechanism. Besides, the extreme point and inflection point of the spread and diffusion model are also discussed. In the case study section, 723 Wenzhou Train Crash and its public opinion crisis are fitted and analyzed by using the public opinion spread and diffusion model.
