Abstract

With Hegyi single-tree competiton index model , the intraspecific and interspecific competition intensity in Shima superba , one of the common species in evergreen broadleaved forest in Tiantai Mountains of Zhejiang Province is quantitatively analyzed .The findings show that the intraspecific competition intensity in Shima superba decreases gradually with the increase in tree diameter .The intraspecific competition in Shima superba is weaker than that in Castanipsis eyrei .The degressive order of the intraspecific and interspecific competition in Shima superba is as follows :Castanopsis eyrei , Schima superba intraspecies , Piuns massoniana , Quercus galndulifera var .brevipetiolata , Daphniphyllum oldhamii , Ilex wilsonii and Castanea henryi .The relationship of the competition intensity between the competitive tree and the objective tree conforms to powrer function rule .The intraspecific and interspecific competition intensity in Schima superba can be simulated and forecasted .Known from the forecasted results , the competition intensity becomes small and the range is not large when the diameter at breast height of Shima superba reaches 20 cm , There is significant negative correlation between the competition intensity and the diameter at breast height of objective tree .[ Ch , 5 tab .14 ref .]
