一、概述在茫茫林海发生林火,无论地面了望或空中飞机巡逻,以往都是用眼睛看起烟来发现。但是初起小火烟很少,不易发现,一旦浓烟顿起,已酿成灾。在大火蔓延时,烟雾弥漫,在地面或是在空中都很难确定火线的真实位置和火场发展动向。至于在夜间就更无法根据地形特征来辨认火场的位置。靠目测确定火场边沿分布有时误差很大。防火指挥人员往往因情况不明而贻误战机的例子是屡见不鲜的。林火控制首先取决于“火情明”,这就是准确地监视和掌握火情,及时报道失火地点和火场发展动向。装在飞机上的“红外扫描相
First, an overview of the forest in the vast forest fire, regardless of the ground or air plane patrol, in the past are looking with smoke to find the eyes. However, since the beginning of a small number of small fire smoke, not easy to find, once the smoke Dayton, has become a disaster. In the spread of the fire, the smoke filled the ground or in the air are very difficult to determine the true location of fire and fire developments. It is even more difficult at night to identify the location of a fire field based on topographic features. By sight to determine the edge of the fire distribution sometimes great error. It is not uncommon for fire commanders to bung their fighters for unknown circumstances. Fire control first depends on the “fire out”, which is accurate monitoring and control of the fire, timely reporting of the location of fire and fire developments.
