摘要
本文利用177株柳杉解析木材料,分立地质量级、密度级研究立木材积生长率与胸径的关系,提出了几个简单公式并据以编制出相应的一元材积生长率表,为估测柳杉林分材积生长量提供依据。
Baesd on the measurements of 177 temporary sample plots and 177 mean sample trees analysed, this paper deals with the relation between the volume growth percentage and the diameter at breast height in terms of site quality or site quality-density for Chinese Cryptomeria. Several simple formulas describing the relationship were obtained and used for the construction of volume growth percentage tables. These tables can be used to estimate the volume growth of stands of Chinese Cryptomeria(Cryptomeria fortunei Hooibrenk ex otto et Dietr).
