摘要: 采用Hegyi 的单木竞争指数模型对浙江天台山常绿阔叶林常见种木荷的种内、种间的竞争强度进行定量分析。结果表明:木荷所受到的竞争强度随着林木径级的增大而逐渐减小。木荷种内竞争较之与其伴生树种甜槠间的竞争弱。木荷种内和种间竞争强度的顺序为:甜楮木荷种内马尾松短柄虎皮楠尾叶冬青珍珠栗。竞争木对对象木的竞争强度与对象木的胸径大小服从幂函数关系, 并可模拟和预测木荷种内和种间的竞争强度。从预测结果可知, 当木荷胸径达到20cm 后, 竞争强度变得很小, 且变化幅度不大。竞争强度和对象木的胸径大小成极显著的负相关关系。表5 参14

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 .]
