| 摘 要： | 依据天然林中的刨花楠解析木资料 ,利用削度方程对其各相对树高处的直径进行拟合 ,并对其干形结构的变化趋势进行分析。研究结果表明 :刨花楠树种的最优带皮削度方程为 :d =1.191170·(1-h/H) ( 0 .3 0 60 49 0 .43 763 4D/H) ·D0 .951175;各径级树木干形的变化规律为 :随着胸径和年龄的增加 ,各径阶树木从树干基部往上的相对形率的减少速度呈增加趋势 ,高径比呈下降趋势 |
| 关 键 词： | 刨花楠 干形 削度方程 形率 |

| Abstract: | Based on the materials of the analysis trees of Machilus Pauhoi in the natural forests, the relative diameter of the relative tree height was simulated and the development trend of the structure of tree form was analyzed by applying the taper equation .The research results show: the best taper equation of diameter over bark of Machilus Pauhoi is d=1.191170 (1-h/H) (0.306049 0.437634D/H) D 0.951175 ; the rule of variance of tree form about each diameter-class is that : the decrease rate of relative factor quotient above the base of tree trunk in all the diameter-class is rising up with the increase of Diameter-breast-high and age, but the ratio of height to diameter is going down. |
| Keywords: | Machilus Pauhoi tree form taper equation factor quotient |
