According to the regional disaster system theory , the formation of a multi-hazard coupling scenario was regarded as the combination of the danger of hazard-formative factors, the sensitivity of the hazard-formative environment, and the vulnerability of hazard-affected objects. In CPI, the hazard-formative factors refer to the uncontrolled energy in the industrial process or the natural phenomena, which may be accidentally released . Due to the special hazard-formative environment associated with CPI, the formation and evolution of a multi-hazard coupling scenario is a complex process, usually leading to a dynamic multi-energy flow coupling physical field .
