航空红外扫描在探测大兴安岭森林火灾中的作用

航空红外扫描仪是森林防火的设备之一,在大兴安岭特大森林火灾中,它在地面被浓烈的烟雾笼罩下及时把地面的火情记录下来,迅速向前线灭火指挥部报告火情地点及火势的发展情况。在一般目视方法无法报出火情的情况下,航空红外扫描所提供的火情资料,成为灭火指挥部调动地面灭火大军的依据。本文简要介绍红外探火的原理和设备,着重介绍红外探火的基本方法和应用效果。该项成果不仅扩大了红外遥感技术的应用范围,而且发展了红外探火的方法。

EFFECT OF AIRBORNE INFRARED SCANNER FOR SURVEYING OF THE FIRE IN DAXINGANLING MOUNTAINS

Airborne infrared scanner is one of installations for detecting forest fire during the huge forest fire in Daxinganling Mountains. It recorded information of the fire through thick smog, and reported immediately to the fire-fighting headquarters on fire sites and information of fire stretching. During the fire, information couldn't be reported by common visual methods, but information provided by airborne infrared scanner became the basis for fighting headquarters to deploy the fire-fighting forces. This paper presents briefly principles and installations of infrared scanning for fire surveying. It places the emphasis on basic methods and results of application. The results not only broadened application scope of infrared remote sensing technology, but also developed infrared method for fire surveying.
