摘要
林分结构是森林培育和森林经理的主要内容,是生态系统功能发挥的基础。黑松林分是山东半岛主要的森林类型,但目前关于其林分结构尚缺少系统研究。以青岛崂山黑松林分为研究对象,通过对10个面积为800~1 000 m^2的样地进行每木检尺与计测,系统地研究了黑松林分的直径结构、树高结构和树冠竞争因子(CCF)。结果表明:1)崂山黑松林分直径结构基本呈正态分布,但有不同程度的左偏和右偏现象;2)崂山黑松林分的树高结构呈现正态分布,同时也存在不同程度的左偏和右偏现象;3)树冠竞争因子表明林分树冠未完全郁闭。
Forest stand structure is the main content of forest cultivation and management and the foundation of ecosystem function.As the fundamental stand of Shandong Peninsula,the systematic research on stand structure of Pinus thunbergii forest was absent.10 sample plots covering 800-1000 square meters were selected in Pinus thunbergii forest in Laoshan Mountain of Qingdao City to study diameter structure,height structure,and crown competition factors(CCF).The results showed that both the diameter structure and height structure presented normal distribution,but there was left or right bias to some extent.The crown competition factor values(CCF)indicated the stands did not reached full canopy closure.
