摘要
以红松人工林地表可燃物为材料,在实验室内的各级风速条件下,对火行为预测中争议较大的风因子预测模型进行了点烧实验及适用性分析,结果表明,风速在0.9 ～4.6 m/s时,现有风因子模型对红松林下可燃物而言,只有个别较为适用,其中含可燃物属性的复杂模型（Rothermel模型）适用性较强.
We texted the existing wind factor models first. Fuel beds composed of Korean pine needles collected from Korean pine plantations were constructed with varied fuel moisture, loading and depth. Totally 90 experimental fires with these fuel beds were burned inside laboratory under different wind conditions. The results indicate that the exciting models of wind factor are not applicable for Korean pine needles very well when wind speed is in 0. 9 - 4. 6 m/s. The multi-sector model （ model of Rothermel） is better than the others.
