| 摘 要： | 将毛竹(Phyllostachys edulis)竹秆等长分割成40段,分别测量各竹段底边周长、壁厚、节隔厚,研究毛竹竹秆直径与材积的垂直格局,并构建毛竹竹秆直径相对值、相对外围累计材积、相对实际累计材积和相对节隔累计材积与竹秆相对高度的回归模型、毛竹外围材积、实际材积和节隔材积与胸径的回归模型等共7个模型.结果表明:不同胸径的毛竹竹秆直径相对值、各相对累计材积随着相对高度的增加,变化规律表现出显著的一致性,反映了毛竹竹秆结构方面的共性.

| Abstract: | The vertical patterns of diameter and volume of moso bamboo stem were studied in this paper. That bamboo stems were divided into 40 sections at equal length. That the girth, thickness and node of each section were measured. Seven regression models were established to describe the vertical structure of the diameter, volume of timber of moso bamboo stem. Those models were applied to relative diameter, relative apparent volume, relative real volume and relative node volume of timber with relative height of stem, and apparent volume, real volume, node volume of timber with DBH of stem. Although differences appeared on DBH at different moso bamboo individuals,there was striking identicalness of relative diameter and relative volume at vertical direction. It was mainly due to commonness on the vertical structure of moso bamboo stem. |
