摘  要：
文章对长白山云冷杉林云冷杉原始林与云冷杉过伐林内倒木的贮量,以及倒木对更新的影响等进行了研究。结果表明,云冷杉原始林内倒木贮量为241.7 m~3/hm~2。云冷杉过伐林内倒木贮量为66.9m~3/hm~2。两种林型内倒木上幼苗结构均随级别增大而减少。云冷杉原始林Ⅲ.Ⅳ,Ⅴ级倒木株数占到96%,倒木贮世随级别的增大而增加,Ⅲ,Ⅳ,Ⅴ级倒术贮量占到97.2%;云冷杉过伐林只有Ⅲ级与Ⅴ级存在倒木,Ⅴ级倒木株数占79.4%,贮量占70.8%。倒木上幼苗主要集中在大头端以及倒木中部,小头端幼苗数量较少。

摘  要：
A study of storage of fallen trees and effect of fallen trees on regeneration of PICEA- Fir forest in Changbai mountains.The study revealed that the volume of dead woods in primitive PICEA-Fir forest was 241.7 m~3/hm~2;the volume of dead woods was 66.gm~3/hm~2 in over-cutting PICEA-Fir forest.The number of seedlings on dead wood was declining wih the size classes growing.The number of dead woods was occupied 96% and the vomule was occupied 97.2% of Ⅲ,Ⅳ,Ⅴ decay classes in primitive PICEA-Fir forest.The dead woods only exit in Ⅲ and Ⅴ decay classes in over-cutting PICEA-Fir forest,the number of dead woods was occupied 79.4% and volume was occupied 70.8% of V decay classes.The number of seedlings was mostly accumulated on large diameter portion and center of dead woods.
