摘要： 用有限空间种群增长的逻辑斯谛模型探讨了种群基面积增长规律，指出了云冷杉林建群种在不同状态下的基面积最大增长速度的径级范围，紫果云杉35—40cm，岷江冷杉50—55cm；在不同林分内，建群种具有不同的基面积最大增长期。

Abstract: The growth of tree basal area was well described by logistic model. According to the model, the range of Breast Height Diameter (BHD) can be derived and the maximum growth rate of basal area can be found. The result showed that the growth rate of Picea purpurea are highest at BHD of 35—40cm,while Abies faxoniana at 50—55cm. The maximum growth phases of edificators in various forest are different.
