分析了“5·16”红花尔基樟子松林重大火灾的气候条件是前期气候干旱,气温骤升13.6℃;计算的森林可燃性的综合指标395、423与实际情况相符;火灾蔓延迅速的风力4￣5级;利用极轨卫星遥感资料和地理信息系统计算了在天空无云、风力4￣5级时的火场火势的蔓延速度一般为137￣173hm2/h,可为以后的林火预报提供参考。
The climatic conditions of “5.16” Pinus sylvestris var.mongolica forest fires were drought in previous period and the temperature rose by 13.6 ℃. The calculated comprehensive indicators of forest flammability 395, 423 were consistent with the actual situation; the fire spread rapidly Wind 4 ~ 5; the use of polarographic satellite remote sensing data and geographic information system calculated in the sky cloudless, the wind 4 ~ 5 when the spread of the fire scene fire rate is generally 137 ~ 173hm2 / h, for the future forest fire forecast for reference.
