Abstract: Abstract: It is necessary and urgent to construct Chinese own scientific and engineering knowledge system for emergency response, train the talents of organization, management and engineering technology, effectively deal with emergencies and support large countries' emergency response. Based on the demand of reality, policy transmission and discipline law, this study adopts knowledge production theory, and combines the related research on emerging emergency science and engineering knowledge system. The paper describes and classifies the content of each knowledge branch and the main body of the knowledge system of emergency science, and expounds the complex adaptive characteristics of the knowledge system, the structure of emergency science and engineering knowledge system is constructed, which is composed of three subsystems: knowledge subject subsystem, communication subsystem and application subsystem. The results show that this study can provide reference for the theoretical and applied research on the specific operations of emergency management, and help the emergency practioners to understand the whole process of emergency work systematically from the perspective of knowledge production, and further expand the construction of modern emergency management theories and methods.
