【摘要】 本文对辽东地区色赤杨林分的生长量、结构特征、物候期、地表可燃物种类组成及可燃物载量进行调查研究，并在室内对当地林木凋落物的燃烧性进行试验测定，在野外林分中对色赤杨自然阻火情况进行调查，证明该树种的抗火性能较强，不易燃烧，适宜在大面积针叶林中营造防火林带。更多还原

【Abstract】 The investigation of growing forest type structure, phenological period, forest fuel classication, forest fuelweight and forest litter combustibility were made. The results showed that fire resistance or Alnus tinctoria was beeterbetter than that of other broadleared trees, and it had a significant natural fire resistance effect. So it be could beused to buid fire prevention belts in artificial coniferous forest.更多还原
