摘要
本文根据粤北低山丘陵地区收集小红栲（ＣａｓｔａｎｏｐｓｉｓｃａｒｌｅｓｉｉＨａｙａｔａ）解析木１２株和标准木３１株的资料，通过建立生长模型，分析其生长规律，并用最优分割法将小红栲生长发育过程分为５个阶段，据此进一步划分其龄级和组织龄组。结果表明，小红栲早期的树高和直径生长迅速，继而进入材积速生期和数量成熟期，从而提供该树种的营林理论依据。
This paper analysed the growth process of Castanopsis carlesii according to the data of twelve stem analysis and thirthy-one sample trees,which were collected from the north Guangdong mountain and hill regions.Based on that we established a growth model of Castanopsis carlesii and worked its pattern.Then we divided the growth process into fivestages by the first-rate volume-period method and further set up an age-class and age-group categorisation for Castanopsis carlesii.The result showed that the Castanopsis carlesiigrew fast in the early stage in height and diameter,then cane rapid growth in volumeand quantitative maturity.Therefore this paper provides a theoretical basis for silvicultureof this species.
