In this paper,the competitive diffusion process of food safety Internet public opinion has been modeled as a multi-species Lotka-Volterra system. The three diffusion modes of collaboration,prey-predator,and complete competition between different opinions have been discussed. The model was validated by applying it to the case of '#pinhole crabs' microblogs from Weibo.com.
