This paper contain어 an actual investigation of a wildfire which broke out on 23 April R 1996 in Go-sung Kun, Kang-won Do examined the calories and the total calories of the m main trees which were Quercus variabillis and Pinus densiflora. There were three important f fire spread factors which were weather condition, fuel condition and terrain. The weather c condition was the most dangerous alarm level. The fuel condition having a high calory v value, Pinus densiflora made up 63% of the forest. Terrain of the forest were mostly c covered by steep slopes and complicated line construction. This experimental calorie study a about Pinus densiflora and Quercus variabillis showed that Pinus densiflora had 13,341‘caνg a and Quercus variabillis had 9.64kcaVg. In the case of weight loss of pyrolysis, Pinus d densiflora had a higher percentage rated 35.71 -10.05% than Quercus variabillis. Accordingly, P Pinus densiflora showed lower than Quercus variabillis in heat resistance
