一场火灾,常使茂密的森林落得满目疮痍,多年来精心培育的树木毁于一旦。每年森林火灾都给国民经济造成很大的损失。大的火灾还使生态环境遭到严重的破坏。森林火灾不仅是林业部门的问题,而且也是自然保护的重要问题。春、秋季干燥少雨,枯萎的树木、草类等植被因人为或自然的原因很容易着火,经风吹,又容易蔓延,酿成火灾。特别是人迹稀少的密林、草原,一旦着火很难及时发现。因此,在防火工作中采用积极有效的措施,随时发现火种是占有重要的地位的工作。在其还没有大面积蔓延之前加以控制,尽快扑灭,更属关键环节。

The big fire has also caused serious damage to the environment. Forest fires are not only a problem in the forestry sector, but also an important issue in nature conservation. Spring and autumn, dry and rainy, withered trees, grasses and other vegetation because of man-made or natural reasons are easy to catch fire, the wind, but also easy to spread, causing a fire. Especially sparsely populated jungle, prairie, once the fire is difficult to find in time. Therefore, taking active and effective measures in fire prevention work, we always find that fire is a work that holds an important place. Control before it has not spread a large area, as soon as possible put out, it is a key link.
