The Regressive Analysis on the Tree-measuring Factor of 5 Species of Clustering Bamboo from the South of Zhejiang Province

On the basis of 500 sample bamboo culms and 5 500 original data obtained from the south of Zhejiang Province, the author analysed the single and double factor relationship between the weight of culm, the weight of branchs and leaves, the total weight of ground part with the height of culm and diameter of breast height measuring tree factor of Bambusa atrovirens Wen, B. textilis McClure, B. pachinensis var. hirsutissima W. C. Lin, Lingnania wenchouensis Wen and Sinocalamus latiflorus McClure, the relationship and close level between the breast diameter with the ground diameter, breast diameter with the height of culm etc. and selected out 78 regressive equations.
