摘要
本文详细论述了如何用间伐效应生长量分析方法,将间伐林分断面积总生长量分解为基本生长量、效应生长量两部分进行考察,以及单独定量间伐效应生长量的基本理论及具体途径。 通过对华北落叶松人工林间伐固定标准地的研究分析表明:该树种间伐林分株数按径级分布符合韦布尔分布,林分在不同生长发育时期,其间伐最大效应生长量所对应的保留株数不同。
In this paper, we describe both the base theory and particular method of the response increment analysis and how to partition the total basal area increment into two fundamental components; the base increment and the response increment. By studing the thinned artificial even-aged Larix Prinripis-ruipprechtii forest, its diameter distribution, and the stocking whichis relavant to the maximum response increment appears different in the various development period of the forest.
