| 摘 要： | 通过测定和分析云南油杉、云南松、华山松3种针叶树种树皮的厚度、导热系数、外界热辐射作用下的失重过程和树皮内表面温度4个因子，结合3个树种在火烧迹地上的死亡率数据，得出如下结论：树皮的结构、导热系数是决定这3种树种耐火性差异的主要因素，3种针叶树种树皮的抗火性由强到弱的顺序为云南油杉〉云南松〉华山松，与这3个树种的死亡率由小到大的顺序相同。

| Abstract: | Determination on bark thickness,heat conduction coefficient,thermal weight loss and inner surface temperature during external heat radiating,tree mortality rate by forest fire of Keteleeria evelyniana,Pinus yunnanensis,P.armandii resulted that the main factors causing the difference of fire resistance were bark structure and heat conduction coefficient.Fire resistance of different tree bark was: K.evelyniana>P.yunnanensis>P.armandii,but the contrary as the order of tree mortality rate by forest fire. |

| Keywords: | bark structure heat conduction coefficient fire resistance |
