The invention discloses a method for constructing a safety emergency workflow model based on icons. The constructing method comprises the steps that all plan elements in a textualized emergency plan are converted into plan icons and workflow meta models, the corresponding plan icons are called according to safety accident information in the application process, instantiation processing is carried out on the obtained plan icons through the corresponding workflow meta models, and the safety emergency workflow model based on the icons is obtained. According to the safety emergency workflow model based on the icons, the amount of transmitted information of the emergency plan is greatly increased, visual emergency execution information is provided for emergency personnel in an ionic mode, the short-period memory of users at the emergency moment can be enhanced, safety emergency workflow can be monitored in real time, and safety emergency processing efficiency is improved.
