Abstract: In order to further improve the level of forest fire disposal technology in China, the application status of forest fire extinguishing technologies are summarized based on field survey, attending forum and literature analysis. This paper analyzes the main types, development history and practical application effects of forest fire extinguishing agents, introduces the current situation and main problems of fire extinguishing bomb, individual fire extinguishing equipment and forest fire truck, and points out the important role of aviation fire extinguishing in forest fire fighting. Furtherly comparing with the overall situation of foreign forest fire extinguishing technology, this paper points out the shortcomings of the current forest fire extinguishing technology in China in standard formulation, new product scientific research and application. Some suggestions are then given on the follow-up development direction of strengthening scientific research investment and paying attention to environmental protection performance, which provides a scientific reference for the prevention and control of forest fire.
