摘要
林地可燃物火行为的研究是林火管理、林火预报、火灾扑救的理论基础,森林可燃物类型及特性对可燃物的火行为具有非常重要的影响。通过室内点烧试验,分析油松辽东栎凋落叶可燃物载量对火行为的影响。结果表明:载量对蔓延速度有显著影响,载量越大,蔓延速度越快;可燃物载量对蔓延速度、火线强度、火面强度、火焰高度都有显著影响,均呈正相关,对火线强度、火面强度、火焰高度有极显著影响。降低地表可燃物载量能够有效降低发生地表火的潜在危险性。
The research on fire behavior of fuel load of woodland is the theoretical foundation of forest fire management, forest fire forecast, fire fighting.The types ＆ characteristics of forest fuel load have very important impacts on forest fire behavior.The effects of fuel load of litter of Pinus Tabulaeformis ＆ Quercus Liaotongensis on fire behavior were analyzed by burning experiment inside laboratory.Result shows that：The fuel load has significant influences on spread velocity of combustible, the greater the load,the faster the rate of the fire spread.Fuel load has a great influence on the rete of the fire spread,fire intensity and flame height.The fuel load has a positive correlation with the spread speed of combustibles, the intensity of fire line, the intensity of fire surface, and the height of the flame.According to the results, it is found that reducing the load of surface combustibles can effectively reduce the potential danger of surface fire.
