林木虽然畏惧火的吞食,但森林树种中确有一些不怕火的“耐火金刚”。人们在森林火场发现,有的树种全株被熏黑,叶片全部烧焦或烧光,甚至树干烧毁大半,也能存活,仍有萌发再生能力;有的着火时不易产生火焰,使火势无法蔓延,从而发现了具有抗火价值的防火树种。用这些树种大面积造林或营造防火隔离带,不仅具有森林的各种效益,且在防止森林火灾的扩大,减少灾害的损失,尽快恢复森林复被方面,有独到的作用。防火树种,一般具有下列特征:叶厚、冠茂、枝叶水分多、树脂少、树皮栓皮层厚、不易燃烧;
Although the fear of forest trees devour the fire, but there are some forest trees are not afraid of fire, “Fire King Kong.” People in the forest fire found that some species of whole plant was blackened, all the leaves scorched or burn, and even the trunk burned more than half, can survive, there are still germination and regeneration; some fire is not easy to produce a flame, so that the fire can not be spread , Thus found a fire-resistant tree species with fire resistance. The large area afforestation or the construction of fire isolation zone with these species not only has the various benefits of forests, but also plays a unique role in preventing forest fires, reducing losses and recovering forests as soon as possible. Fire tree species generally have the following characteristics: leaf thick, crown Mao, branches and more water, less resin, bark cork layer thick, not easy to burn;
