| | 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 sprin... | | 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。 | | 文摘来源 | | There are many kinds of burning in nature,but forest burning is the most complicated one.The old so-called three-main-factor of burning (fuel, oxygen and a given temperature) can not be enough to explain the complicated phenomenon along with the development of modern fire management.So, the paper advances the theory of Forest Burning Link and gives a new explanation about forest burning.Based on the mainfactors of fuel types, fire resource, fire environment and fire behavior etc., the theory puts forward th... | | 自然界有多种燃烧现象,其中森林燃烧是最复杂的一种。随着现代林火管理的发展,过去所谓的燃烧三要素(即可燃物、空气和一定的温度)已不能完全解释这种复杂的现象。因此,本文提出了森林燃烧环的理论,对森林燃烧现象作了新的解释。该理论从可燃物类形、火源、火环境及火行为等出发,提出了森林燃烧环的概念和结构,来阐明森林燃烧环中各因子之间的相互关系。在实践中,可按森林燃烧环来绘制火险图,作为森林防火规划设计的理论依据;并确定扑火的方式、方法,估测扑火所需要的人力和物力,评价林火损失及制定今后森林恢复应采取的措施;同时森林燃烧环还可确定营林用火安全期,选择有效的方法、技术和指标。 | | 文摘来源 | | Three main factors-fire resistant ability, bioecological and silvicultural characteristics about 37 tree species have been analysed in the laboratory ; and have been judged and divided into grades by using Fuzzy mathematics method.
