Absorbing the advanced experience of forest fire warning and control in the world, establishing the fire risk rating system based on combustion mechanism can further improve the comprehensive ability of forest fire prevention and control in China and reduce the loss of forest resources. Based on National Fire Danger Rating System (NFDRS), the paper introduces the development history, technical method and system structure, argues that NFDRS is a physical model based on combustion mechanism and experiments, considers the contribution of different fuels to fire, calculates and provides comprehensive indexes to facilitate the planning of fire control activities. The structure and method of NFDRS are applicable to China with complex climate and diverse vegetation types. Therefore, the paper discusses the key technologies in the system, such as the calculation of moisture content of combustible and the calculation of fire protection index. By considering the current situation of forest fire prevention in China, the paper proposes the introduction of NFDRS into forest fire management and fire control strategy in China in order to provide references for establishing national fire danger system in China.
