摘要
本文对天山云杉人工幼林树冠结构以及树冠结构与林木之间的关系进行了研究，并基于生物学原理，在确定有效树冠的法础上，通过决定林木能力的树冠特征对其人林分间伐中的应用进行了初步研究。
This paper studys the crown strucrure of the current young growth of Schrenk spruce and the rhlation between the crown structure and the forest tree,meanwhile,according to the biological principle,based on the effective crown,probes the application to the stand intermediate cut by means of the crown features determing the growing capacity of the forest tree.
