Abstract:

Abstract： Bark could protect phloem and cambium of the tree bole. Flame retardancy of bark should be taken into account while screening tree species for the fire protection. The flame retardancy characteristic parameters were put forward based on bark structure，approximate analysis and thermal weight losing，inner surface temperature of bark during external heat radiating of 5 main tree species for forestation. The order of flame retardancy of bark from strong to weak was：Alnus nepalensis，Keteleeria evelyniana，Pinus yunnanensis，Eucalyptus maideni，Pinus armandii. According to the flame retardancy of bark and the fire resistance of the 5 tree species，we commended forest fire protection measures correspondingly.
