This paper has treated the forest fire as a combustion system.The

森林火灾作为燃烧系统,和森林可燃物的数量,含水量以及分布状态有关,也和当时的蔓延速度和可燃物的燃烧速率有关。按照不同的要素,包括初始燃烧速率,蔓延速度和地表杂草枯枝落叶层单位面积上的负荷量,以确定林火强度。火爬坡时,蔓延速度增加,火强度相应地增加;相反,下坡火的蔓延速度减缓,火强度也相应地变小。根据计算结果,林火强度不超过1×10~3千瓦/米~2是低强度,这时1立方米内的可燃物被烧掉的数量不超过3公斤,地表杂草枯枝落叶层的可燃物数量(W_0)不超过2.5公斤。即便地表可燃物保持在2.5公斤以下,蔓延速度大于3米/分时,火强度均将超过1×10~3千瓦/米~2。地被物数量大,火蔓延速度也大的林型中将产生最大的火强度,这和过去的经验是完全符合的。

Based on the analysis of various air masses which control the weather systems of China, the paper expouds the seasonal law of fire occurrence in China. The movement of the place where the polar air mass and the horse latitude pacific air mass meet (joined band) affects the fire seasons and fire occurrent rates in the east part of China. Therefore, there is a close relationship between the movement of the joined band and the fire seasons of various areas.The fire season moves from south to north in the spring...

Based on the analysis of various air masses which control the weather systems of China, the paper expouds the seasonal law of fire occurrence in China. The movement of the place where the polar air mass and the horse latitude pacific air mass meet (joined band) affects the fire seasons and fire occurrent rates in the east part of China. Therefore, there is a close relationship between the movement of the joined band and the fire seasons of various areas.The fire season moves from south to north in the spring and from north to south in the autumn. Once we have learnt the law, we can easily make a medium-term fire forecast in order to prevent the forest fire.

本文通过分析控制我国天气系统的各种气团活动规律,来研究我国森林火灾发生的季节性规律。我国东半部地区预防森林火灾的季节是随着变性极地气团与副热带太平洋气团在南北移动中,两气团的交绥位置变换时,影响着我国南方、北方的防火季节和森林火灾的出现频率。因此冷暖气团的交绥位置的移动与各地森林火灾的发生时间紧密相关。森林火灾的规律在春季是由南方向北方逐渐移动,秋季则由北方向南方逐渐移动。掌握了这一规律性,可做好中期火险天气预报,提前做好防火预防工作。以达到预防的目的。

A catastrophic forest fire had occurred in Daxingan Mountain area in the Northeast China from May 6 to Jane 2,1987, The losses are very heavy. The paper analysed the weather system for which the fire occurred according to the change of the weather before and after the fire, and studied the development process of hot and cold air mass on the basis of the ground map and aero-map. The paper pointed out that the mongolian cyclone was main fire weather system in the Daxingan Mountain Area. If the area is in the control of hot air mass. the temperature will rise rapidly and there will be no rain during the pass of cold front. At this time,the windy and dry weather will occur and dry weather will occur and it is most dangerous fire weather.Therefore, we should take precautions and plan manpower and material resources before fires occur according to the the change of fire weather system.

1987年5月6日至6月2日在大兴安岭林区发生了特大森林火灾,损失惨重。本文根据发生火灾前后的天气形势变化,分析研究了发生林火的天气系统。根据地面图,高空图研究冷暖气团的发生发展过程,蒙古气旋是导致大兴安岭林区森林火灾的主要天气系统。大兴安岭林区在暖气团控制下,增温明显,冷峰过后又无降水,产生大风干旱自寺天气形势。这是高火险级天气,极易跑火成灾。因此可根据天气形势的变化,有效的布防力量,以做到有效预防和及时扑救,减少损失。
