ANALYSIS OF THE GROWTH PROCESS OF CASTANOPSIS CARLESII IN THE NORTH GUANGDONG MOUNTAIN AND HILL AREAS

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.
