南京紫金山毛竹平均胸径与立株度之间的关系
Relationship between the Mean Diameter of Breast Height(DBH)and the Number Per Unit Area of Moso Bamboo Stands in Zijin Mountain
摘要
Abstract
In this study,30 sites each 10 m ×10 m in the moso bamboo pure forests were investigated in Zijin Mountain,and the DBH of ev-ery bamboo was measured.The Normal and Weibull distribution functions were used to judge the distribution type of pooled bamboos' DBHs. After log-transforming the data of mean DBH and corresponding density,the linear regression to examine whether the DBHs of moso bamoo fol-low the self-thinning law was used.The results showed that the DBHs of moso bamboo in Zijin Mountain follow the Weibull distribution func-tion,with a median of 9.1 cm.There was a significant self-thinning relationship between the mean DBH and spatial density(namely the num-ber per unit area),that was,with spatial density increasing,the mean DBH continuously decreases.When the mean DBH was predicted to be 9.5 cm, and the spatial density reached 3 276 hm2.Such a standard of density arrangement was recommended in this area because bamboo was then of high ornamental value based on the trade-off between the number per unit area and the mean DBH.关键词
