摘  要:
对斑竹林的调查结果表明:不同林分类型斑竹林的胸径、株高、枝下高、秆重、整齐度、均匀度6个结构因子差异显著,立竹密度、壁厚因子差异不显著;提出优良林分"密度11 000株/hm2、胸径5 cm、株高11 m、枝下高4 m、秆重8 kg,林相整齐、均匀"的结构标准;立竹胸径、地径、株高、枝下高、秆重因子间相关显著;株高、枝下高、胸径、全重、秆重和均匀度是林分结构的主成分,贡献率69.6%。

摘  要:
The investigation results of Ph.reticulata CV.Lacrima-deae Keng et Wen show that:there are significant differences in six structure factors such as diameter at breast height,plant height,under branch height,culm weight,uniformity and evenness in different types of Phyllostachys bambusoides f.lacrima-deae Keng f.et Wen.Whereas the differences in Stand density and bamboo wall thickness factor are not significant.Therefore,the excellent stand structure standard is "density 11 000 plants/hm2,diameter at breast height 5 cm,plant height 11 m,under branch height 4 m,and culm weight 8 kg,and uniform forest appearance".The correlations among the factors of diameter at breast height,ground diameter,plant height,under branch height,leaf weight and full weight are remarkable.The principal components of stand structure include plant height,under branch height,full weight,culm weight and evenness,the contribution rate is 69.6%.
