Conceptual Framework for the Construction of a Natural Disaster Prevention and Mitigation System

Under the context of global climate change，China has witnessed frequent occurrences of major natural disasters，resulting in extensive damage to infrastructure and numerous mass casualty incidents. The situation of risk prevention and control remains severe，making the establishment of an efficient and coordinated natural disaster prevention and mitigation system a fundamental and strategic pillar for ensuring national security and development. This paper begins by reviewing key scientific and technological challenges in natural disaster prevention and mitigation. It then constructs eight major systems from three dimensions—theoretical innovation，technological innovation，and management innovation—including：fundamental theoretical system，hidden risk identification system，monitoring technology system，early warning technology system，assessment technology system，engineering management system，emergency response system，and regulation and management system. The specific contents and interrelationships of each system are clarified. Based on the current status and shortcomings of natural disaster prevention and mitigation efforts in China，specific recommendations are proposed to advance the construction of these systems，covering basic research，technological development，and international cooperation. The aim is to provide decision-making references for the advancement of scientific disaster prevention and mitigation initiatives in the country.
