| 摘 要： | 研究了大兴安岭地区不同林型林隙的更新密度、边缘木数量及形成原因,结果表明:1)林隙一般由11~24株落叶松、白桦所形成,平均为16.94株;形成方式主要有立枯、折干和拔根倒,11.8%为折干,35.3%为立枯,41.2%为拔根倒。2)林隙所在坡位中58.9%为中下和下坡位,41.1%为中上坡位。3)在杜香-落叶松林、草类-落叶松林和藓类-落叶松林更新密度所受到的制约因子不同,杜香-落叶松林的林隙更新主要受坡度的影响,草类-落叶松林的林隙更新主要受长短轴比的影响,藓类-落叶松林的林隙更新主要受边缘木数量的影响。 |

| Abstract: | This paper studies the regeneration density of different types of forest gaps,the number and causes of the edge of wood.The results showed that gaps are generally formed by 11 to 24 larch and birch trees with an average number of 16.94 trees,which includes standing dead trees,broken trees and uprooted trees.Of those trees,11.8% are broken trees,353% dead standing trees and 41.2% uprooted trees.Gap where the slope was lower in 58.9% and slope position,41.1% were in the upper slope.Ledum leaves in the forest,... |
