Emergency management of unconventional events is a great challenge to all levels of government. This challenge comes from the high-uncertainty, the high-destructive and high-urgency of “unconventional” and “unexpected” events, which make it difficult to deal with. According to the features and evolution mechanism of emergency, this paper constructs a preparation system of emergency. The preparation system includes core level, frame level and rule level, and each module of the system was discussed. We analyze the system through the case study of the emergency management of Wenchuan earthquake. China promotes its preparedness system through the earthquake.
