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 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.
