| 摘 要： | 在普文林场内选择具有代表性的山桂花人工林,应用标准木树干解析法,对14年生山桂花人工林开展生长过程研究,结果表明:14年生山桂花人工林平均胸径14.10 cm,平均树高16.40 m,密度1 140株/hm2,林分蓄积量达144.78 m3/hm2。林木胸径生长分化在2～3年即开始,5年生以后差别更加增大,树高生长的分化在14年生时仍不明显,表现出速生特性,林分密度调整可从5年生时开始。林中优势木树高比平均木高5.25 m,胸径比平均木大6.70 cm,单株材积为平均木的3.10倍,说明山桂花优树选择有较高的增益。胸径与材积回归曲线方程为V=0.116 439-0.020 579 D+0.001 449D2,树高与材积回归曲线方程为V=2.342 4-0.290 614 H+0.009 286H2。

| Abstract: | We studied the development of 14 year old artificial forestry of Paramichela baillonii tree in Puwen Forest Farm by the way of standard trunk section.It showed that these 14 year old trees were 14.10 cm in DBH(diameter at breast height) in average,and tree height 16.40 m,at average density of 1 140 trees/hm2,and stand mass reached 144.78 m3/hm2.We found that their DBH begin to differentiate at about 2~3 year old of the trees and it was significant when at 5 year old.While that of tree height was not signifi... |
