【目的】目标树密度作为近自然森林经营的重要经营参数,确定林分不同发展阶段的目标树密度可为近自然森林经营提供理论依据。【方法】以湖南省永州市金洞林场闽楠人工林为研究对象,基于连续6 a调查得到的9块固定标准地数据54个,临时样地数据10个,共64个样本量,建立等树高线、最大密度线、等疏密度线、等直径线和自然稀疏线等5个密度控制图的相关模型,通过这5个模型编制闽楠人工林林分密度控制图,利用林分密度控制图,得到闽楠人工林各林分发展阶段的目标树密度。【结果】在保证实用性的前提下将闽楠人工林的生长过程分为五个发展阶段:当闽楠人工林处于建群阶段和竞争生长阶段时,林内生长的闽楠尚...

【Objective】Target tree density is an important management parameter of near natural forest management.The determination of target tree density at different development stages can provide a theoretical basis for near natural forest management.【Method】Taking Phoebe bournei plantation in Jindong forest farm of Yongzhou city,Hunan province as the research object.Through six years of continuous investigation,we obtained 54 data of 9 fixed standard plots and 10 data of temporary sample plots,with a total of 64 sample sizes.Five models of contour ...
