摘要： 为了解火行为指标影响因素，采用点烧试验方法，对妙峰山林场可燃物油松和栓皮栎枯叶地表火行为进行了研究。结果显示：火焰蔓延速率、火焰长度和火线强度的显著影响因素均为风速和坡度（P<0.05）；而可燃物厚度和针阔叶比例对火焰蔓延速率、火焰长度和火线强度影响较小，未达到显著性水平（P>0.05），且在风速、坡度、可燃物厚度和针阔叶混合比例4 个因素中，风速是最主要影响因素。在以风速4 m/s 进行试验时，最大蔓延速率、火焰长度和火线强度分别可以达到：2.357 m/min、67.329 cm和119.622 kW/m。

Abstract: To understand the influence factors of the fire behavior, we studied the fire behavior in Miaofeng Mountain based on the experimental fires. The results showed that: The significant influence of speed of propagation, fire line intensity and flame length was the wind speed and slope(P < 0.05). However, the influence of the fuel depth and the percentage of needles to speed of propagation, flame length and fire line intensity was relatively small, which did not reach a significant level (P >0.05), and the most significant influence was the wind speed in the four influence factors, When the wind speed is 4 m/s, the maximum spread rate, flame length and fire line intensity can reach 2.357 m/min, 67.329 cm and 119.622 kW/m.

Key words: fire behaviors, speed of propagation, flame length, fire line intensity, Miaofeng Mountain
