Disasters can have a serious impact on society and ecosystems, causing significant social, economic, and ecological losses. Scientific assessment of disaster risk is the basis for disaster prevention and mitigation. Protected areas are hot spots for regional disaster risk management. During the construction of a national park system and the reform of the protected area system, the national park stands out as one of the most important areas that conserves critical ecosystems as well as provides public welfare. Efficient disaster risk assessment is necessary to support different management objectives such as ecosystem management, visitor management, and local community. Based on the concept of disaster risk management, this research applied the Pressure-State-Response (PSR) model to reflect dynamic management processes. In view of the different disaster risk receptors in the national park, the hazard of disaster-causing factors and environments, and the vulnerability (including sensitivity, exposure and adaptability) of disaster risk receptors were matched to the PSR model to establish a comprehensive disaster risk assessment index system. This research aims to provide a theoretical and scientific basis for disaster risk management in a national park to serve diverse management objectives.
