Abstract:

China′s crisis management lacks a clear conveying of information and therefore is not an efficient crisis handling mechanism.Crises are not taken as dynamic continua and are treated as separated fragments，which will often generate vacuum areas in communication.Stimulated by public opinion on the Internet crises may evolve into more serious ones.Therefore，in handling crises，topic management may contribute to leading public opinion to a more friendly side and thus minimizes the damage of crisis and avoid further crises.

Key words: blocking, Internet public opinion, interpersonal communication, mass communication, crisis communication
