摘要
1987～1989年对毛竹林的结构进行了研究。结果表明,竹杆容重随年龄的变化反映了毛竹个体独特的生长分化特点。随着立竹度的增加,竹株按年龄分布大致均匀化。竹株按径阶分布遵从威布尔分布,但随生产力提高,则向正态分布过渡。
Successive surveys were made in bamboo (Phyllostachys pubesc-ens Mazel ex H. de Lehaie) groves in Dagangshan region, Jiangxi Province from March 1987 to Sept. 1989 for analyzing their structure characteristics which are presented in this paper. The result shows that the unit weight of culm changes along with the age of culm. Its change rules have shown the unique style of bamboo growth and differentiation. The number of bamboos of various ages trends to be approximately the same with the increase of density while diameter follows weibull distribution, but it will be transformed to normal distribution when its stand productivity and density rise.
