一般草原火火势平稳,无突出火头,强度较森林火低,因此风力灭火机是扑救草原火较理想的灭火机具.但多年来在使用灭火机扑打草原火时,往往运用的战术较简单,当遇到气象因子发生变化或可燃物分布复杂.火势加大时,就采取以火攻火的方法来扑救.这种方法虽然很实用,但风力灭火机的使用效率却很低,而且以火攻火的方法又会造成很大的资源浪费,因此我们应当认真探讨如何提高 Generally speaking, grassland fires have a stable fire situation, with no prominent fire head and lower intensity than forest fires, so the wind fire extinguisher is an ideal fire extinguishing tool for fighting fires in prairie fire.But the tactics often used when using fire extinguishers to defeat prairie fires for many years are relatively simple. Encountered changes in meteorological factors or the distribution of combustible material.When the fire increases, to take the method of fire attack to save the fire.This method is very useful, but the use of wind extinguishers is very low efficiency, and the fire attack The fire method will in turn cause a great waste of resources, so we should seriously discuss how to improve
