| 摘 要： | 采用回归模型对海子坪天然毛竹无性系种群地上部分各构件单位生物量进行拟合为:W秆=2.867 7+0.007 3D2H、W枝=0.001 0D2H、W叶=-0.591 5+0.102 8D和地上部分总量W总=2.661 5+0.008 8D2H;秆、枝、叶的生物量分别占地上部分总生物量的88.48%、8.59%和2.93%;整个种群的生物量积累是随着年龄的增大含水率逐渐减小和生物量积累逐渐增多的过程. |

| Abstract: | The study uses the regressive model to adapt overground biomass of individual component unit of clone population of natural Davidia involucrate in Haixziping.In details,Wculm=2.867 7+0.007 3D2H,Wbranch=0.001 0D2H,Wleaf=-0.591 5 + 0.102 8D and Wtotal overground=2.661 5 + 0.008 8 D2H.The biomasses of culm,branch and leaf account for 88.48%,8.59% and 2.93% of total overground biomass respectively.The accumulation of the biomass of whole population is an increasing process with the accretion of age,decreasing o... |
