摘要
用材林经营的目标是生产木材,尤其是大径材高品质的木材。通过科学合理地调整林分结构,可以有效促进林木生长,生产出大径级木材,满足对高品质、大径材材种的需求,达到森林经营的目标。科学有效的林分作业法是调整林分结构的具体措施。利用吉林蛟河阔叶红松林样地数据,分析林分垂直结构特征,论述森林发展类型框架、作业法设计的机理以及包括全周期经营的技术要素等,并提出以林分垂直结构为导向的红松-大径材作业法的设计方法。旨在为阔叶红松林大径材培育提供现实途径,为森林经营作业法设计提供示范参考。
The harvest of forest management is mainly in large-diameter trees.How to rationally and effectively adjust the structure of forest management stand to form a high productivity stand and take into account the economic and ecological benefits of high-quality target trees is an urgent problem to be solved.Based on the sample plot data of broad-leaved Korean pine forest in Jiaohe,Jilin province,this paper analyzed the vertical structure characteristics of forest,discussed the framework of forest development types,the design mechanism of operation method and the technical elements including full-cycle management,and proposed a design case of Korean pine-large-diameter timber operation method guided by the vertical structure of forest,in order to provide a realistic way for the cultivation of large-diameter timber of broad-leaved Korean pine forest and for forest management.This demencfration provided a model reference for the design of forest management practices.
