摘　　要：在森林防火戒严期,用自行设计的装置对云南主要造林树种华山松(Pinus armandii)进行了不同温度、时间作用下的树干耐火性试验,用红四氮唑对高温作用后的树干韧皮部进行了染色,经勾绘、扫描后用Photoshop软件将死亡的韧皮部处理成易于计算机识别的纯色,用Visual Basic6.0编写的程序计算了树干韧皮部的死亡率,初步分析了华山松树干耐火性率与树干直径、树皮厚度、受热温度、受热时间的关系,据此提出了相应的森林消防措施。Fire resistance of Pinus armandii bole were tested with fuel bed designed by the authors during the prohibitive period of forest fire. The mortality rate was accounted with a program developed by the authors with Visual Basic 6.0 after the phloem of samples were soaked with 4% 2,3,5-triphenyltetrazolium chloride （TTC） solutions, then painted and scanned the distributing map of mortal and living phloem, purified the map color with Photoshop. Relationships between fire resistance of the bole and diameter, wood bark thickness, temperature, and heating time were anayzed. Countermeasures of forest fire protection were put forward.
