林分状态与择伐技术指标的关系
Relationship between Stand State and Technical Index of Selection Cutting
【摘要】 通过对立木及各组径级水平级的划分,分析了成过熟阔叶林分的资源分布状况及林分状态,为采伐优化设计特别是采伐强度的确定提供了一种有效的方法.结果表明:蓄积量相同的林分,其林分状态差异很大;各组径级水平级、特别是大径木和过熟木径级水平级是确定采伐强度的关键因素
【Abstract】 By dividing standing timber and diameter classes into different levels,the resources distribution and stand state of mature mixed broad leaved forest were analyzed,which offered an efficient method for the optimal design of harvesting and determination of cutting intensity.The results showed:stands are the same volume,but the difference in stand state,the levels of various diameter classes,especially large diameter trees and over mature trees were the key for determining the cutting intensity.
