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.
