Abstract:
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.
