[Objective]To evaluate the flammability of branches and leaves of common tree species in Sichuan Province.[Method]Seventy common ecological/timber/economic tree species were selected. Ignition point,heat value,ash content,crude fat content,and moisture con-tent of branches and leaves were measured. Principal component analysis was used to evaluate the flammability of tree species comprehensive-ly.[Result]Flammability varied significantly across different species. High flammable species include Pinus tabuliformis,Pinus bungeana,etc.,low flammable species include Mangifera indica and Malus spectabilis,etc.[Conclusion]This study provides data support for forest fire prevention in Sichuan Province,and tree species with low flammability can be used as potential fire-resistant species.
