Abstract:

In order to prevent the occurrence of urban emergencies, the butterfly mutation theory was used to analyze the occurrence process of various urban emergencies, a mechanism model for the occurrence process of urban emergencies was constructed, and the main reasons for the occurrence of urban emergencies were analyzed. Then, a prevention model for urban emergencies was constructed, and preventive measures for urban emergencies were proposed from the government, units, individuals, and legal levels. The results show that the mechanism model of the occurrence process can reveal the entire process of urban emergencies. The occurrence of urban emergencies is composed of four processes: initial factor changes, continuous initial factor changes, system state transition, and urban emergencies. Based on the occurrence process, the main causes of urban emergencies can be analyzed. The prevention model provides scientific and effective ways and theoretical support for preventing the occurrence of urban emergencies.

Key words: butterfly catastrophe theory, urban emergencies, occurrence process mechanism, prevention model, preventive measures
