摘要: 在落叶松林地对色赤杨林带进行护林阻火试验表明,色赤杨是一种速生耐火树种,5~6a后其郁闭度可达0.9以上;林带下可燃物较其它阔叶树少,仅为0.8kg·m-2;春秋2季火险期内较安全,自然阻火作用明显.

Abstract: Fire-resistance test with Alnus tinctoria forest belt in larch plantations shows that Alnus tinctoria is a fast growing and fire-resistance species, and its shade density after 5~6 years growing is more than 0.9. The combustibles are less in the belt than in broadleaved forest, being 0.8 kg·m-2. It is quite safety during fire risk period of Spring and Autumn, and has a significant natural fire-resistance effect.
