摘要
选择深山樱分布集中地块设置临时标准地进行调查,伐取平均木做树干解析,分析树高、胸径和材积的生长过程。采用Logistic方程对树高、胸径、材积总生长量进行拟合,计算出树高、材积生长曲线拐点,分别划分出树高、材积生长阶段,即生长前期、速生期和缓慢生长期。
Centralized distribution plot of Cerasus maximowiczii was selected to set temporary sample plot.Aver-age tree was cut to take the average stem analysis;growth process of tree height,diameter and volume was ana-lyzed.The total growth of tree height,diameter,and volume are fitted by Logistic equation.Inflection point of the tree height,volume growth curve were calculated;growth stage of tree height and volume were divided respectively, that is,growth phase,fast-growing and slow growth period.
