当前,大兴安岭林区对林火监测主要靠飞机巡护。由于飞机飞行受天气条件和飞行费的限制,不仅巡护密度不够,而且巡护间隔期也长,在火险很高的大风天,又不能起飞巡护,因此,飞机巡护有时在发现火情时,已是大火灾甚至是特大森林火灾。可见,只靠飞机巡护侦察火情,是难以实现“三早”和“三打”的。尽快建立起以瞭望塔为主体的林火监测网,乃是当前护林防火工作的急需。一、国内外林火瞭望塔概况 瞭望塔是林火监测网的主体工程,关系到监测网的建设速度和工程造价,因此,各国都在研制重量轻、造价低、技术先进的林火瞭望塔,以满足防火工作的需要。
At present, forest fire monitoring in the Greater Xing’an Mountains mainly patrols planes. Due to the weather conditions and flight costs, the flight density is not only insufficient, but also the patrol interval is also long. On the windy day with high fire danger, patrolling can not be taken off. Therefore, aircraft patrolling sometimes detects the fire When it is already a big fire or even a big forest fire. It can be seen that it is difficult to realize “three early mornings” and “three dozen’s” only by detecting the fire by aircraft patrolling. As soon as possible to establish a watch tower as the main forest fire monitoring network, but the current urgent need for forest fire prevention work. First, the overview of fire towers at home and abroad Overview Watchtower is the main project of forest fire monitoring network, monitoring network construction speed and project cost, therefore, all countries are developing lightweight, low cost and advanced technology fire tower , To meet the needs of fire prevention work.
