一、我区防火工作的环境伊春林区是我国开发较早的重点林区之一。林业区划面积40000平方公里。南北长约320公里,东西宽约180公里。人口130多万。辖区内道路密度为2.5米/公顷左右。居民点星罗棋布,甚至有的居民散居在林内,野外生产单位多,用火点到处可见,对森林防火极为不利。森林资源经过40年来的采伐,未开采的原始林所剩无几,绝大多数都是过伐林和次生林。林内枯枝落叶较多,林间、沟塘中杂草丛生。在已营造的人工林中,针叶树种约占95%以上,而且大多处于未郁闭成林状态,易燃性极高,一旦燃烧起来,容易形成遍燃树冠火,不但难以扑救,而且损失惨重。
First, the fire prevention work environment in our district Yichun Forest is one of the key forest areas developed earlier in our country. Forestry zoning area of 40,000 square kilometers. About 320 km north-south, east-west width of 180 km. More than 1.3 million people. Road area density of 2.5 m / hectare or so. Residential dotted, and even some inhabitants scattered in the forest, the field of production units and more with the fire can be seen everywhere, is extremely detrimental to the forest fire. Forest resources After more than 40 years of harvesting, there are few remaining untreated native forests, the vast majority of which are over-cut and secondary forests. More litter within the forest, forest, ditch pond overgrown. In the plantations that have been constructed, coniferous species account for about 95% or more, and most of them are in the state of unforeseen closed forests. Their flammability is extremely high. Once burned, the coniferous canopy fire is easy to form and is not only difficult to fight but also has a heavy loss .
