| 摘 要： | 通过毛竹立竹材积构件因子及立竹胸径与立竹实际材积的关系研究,结果表明:立竹全高、胸高竹壁厚与立竹胸径呈显著的正相关,是立竹胸径的从属因子;竹秆相对高度竹壁厚与秆径呈一致性变化趋势,立竹径级与竹秆相对壁厚无相关;构建了立竹胸径与立竹实际材积的数学模型:V=0.007351-0.001875D+0.000291D2,编制出竹林林分结构易测因子立竹胸径的对应材积表。 |

| Abstract: | This paper investigated the relationship of timber volume components and DBH of moso-bamboo stands to the actual timber volume.The results indicated that: both the whole height and wall thickness at DBH of bamboo culm appeared notable positive correlation to DBH,and the two factors were the subsidiary factors of DBH.The wall thickness at relative height displayed the same variety trend to diameter of bamboo culm.The diameter level had no correlation to relative wall thickness.This paper also constructed the mathematical model of DBH and timber volume: V=0.007351-0.001875D 0.000291D2,and established timber volume table corresponding to easy investigated factors of bamboo forest structure. |
| Keywords: | Moso-bamboo(Phyllostachys pubescens) DBH whole height wall thickness of bamboo culm timber volume |
