摘要
在对滇中地区云南油杉、旱冬瓜、云南松、直杆蓝桉、华山松5个主要造林树种树皮进行结构特征分析、工业分析和热辐射作用下树皮质量变化、内表面温度变化测定的基础上,提出树皮的阻燃性参数FRP;按照FRP值大小对5种树皮的阻燃性由强到弱的排序为:旱冬瓜、云南油杉、云南松、直杆蓝桉、华山松。根据5种树皮的阻燃性和林木耐火性差异提出相应的森林消防措施。
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.
