Abstract: Abstract: In order to further improve the efficiency of the emergency communication support work of the fire rescue team for large earthquakes and catastrophes in high altitude and cold regions, and give full play to the value of communication support, the emergency communication support measures and principles in dealing with major disasters and accidents in recent years was studied firstly. Then, the factors that affect the communication guarantee, such as the comprehensive quality and ability, equipment level, team composition, local rescue forces and so on were discussed. After analyzing the weakness of the current typical disaster emergency communication support work and formulating the requirements for the emergency communication support work of the fire rescue team, this paper puts forward specific strategies and measures to improve the internal emergency communication support ability of the team. Finally, the application efficiency of the relevant measures in the "Emergency Mission·2021" and "Emergency Mission·2022" earthquake relief practical exercise in the highland and alpine regions is analyzed. Practice has proved that the strategies proposed in this paper are practical and operable.
