Abstract

To minimize the loss of forest resources by preventing the onset and spread of forest fires, the potential behavior of surface fire in different fuel moisture conditions were studied based on the Rothermel Model in Jiufeng National Forest Park of Beijing. The Rothermel Model is a physical mechanism model which is based on the theory of combustion physics and the law of conservation of energy. BehavePlus 5.05 software was used with input fuel parameters including surface dead branches with different load delays, thickness layer of the fuel bed, moisture content, calorific power, wind speed, and slope, to calculate forest fire behavior indicator of four forest types: speed of propagation, heat per unit area, fire line intensity, and flame length. The results showed that the forest fire behavior indicators of four forest types decreased with increase of fuel moisture content and slope value. High strength of surface fire easily occurred in Pinus tabuliformis forest. Platycladus orientalis Franco forest had a potential of medium strength of surface fire. The Larix principis-rupprechtii was difficult to be burned, and had only a possibility of low strength of surface fire. Owing to more accumulation of surface fuel and convenient ventilation conditions in the stand, Quercus variabilis forest had a potential of medium strength of surface fire in condition of low humidity and drought, easily causing damage to stand structure. Therefore, in process of forest fire prevention, priority should be given to Pinus tabuliformis and Platycladus orientalis Franco forests to timely cleaning the undergrowth fuel and to dearease the fuel accumulation. ［Ch, 5 fig. 3 tab. 19 ref.］
