| 摘 要： | 分析富源县老厂乡灰金竹无性系种群的种群结构和地上部分生物量,结果表明:该地区灰金竹种群年龄结构较为合理,部分竹林在无人管理,经营粗放的条件下,年龄结构呈现老化趋势;灰金竹种群的杆龄结构处于壮中龄期,林分株数和蓄积量在杆龄分布上呈现均衡发展;该地区的灰金竹林种群按直径的分布符合正态分布规律,是竹林较理想的直径结构;灰金竹种群的地上部分各构件的生物量所占比例为杆﹥枝﹥叶.

| Abstract: | The paper analyzes the clonal population structure and overground biomass of Phyllostachys nigra var.henonis in Laochang township of Fuyuan county.The results showe that the population age structure of this kind of bamboo is comparatively rational.But part of bamboo tends to be ageing under the poor management conditions.The structure of haulm age about Phyllostachys nigra var.henonis is strong in age,the number of trees and stocking volume display a balanced development on haulm age distribution.The population shows a normal distribution law according to the diameter distribution,which is the ideal diameter structure.The overground biomass of each part of Phyllostachys nigra var.henonis was as following haulm > branch > leaf. |
