摘要：该研究选择生长在我国南方地区的尾巨桉、尾叶桉、大花序桉、粗皮桉和园角桉等5种桉树人工林树种,对不同树种活立木和伐倒木的生长应变水平进行了比较全面的评估.研究结果表明:①不同树种间,由圆周4个方向测量的活立木生长应变平均值差异显著;而活立木同一高度的不同方向,生长应变差异不显著.②大花序桉在5种树种中具有最低的生长应变水平;而尾叶桉生长应变水平最高.③各树种活立木和伐倒木之间生长应变水平差异不显著.④各树种不同高度间生长应变无显著差异.
In order to evaluate the growth strain of both standing and fallen trees, a comprehensive research was carried out on eucalyptus trees from 5 plantations in south China, including Eucalyptus urophylla×E. grandis, E. urophylla, E. cloeziana, E. pellita and E. tereticornis. The results showed that： 1 ） there were highly significant differences in the mean growth strain from circumferential measurements on standing trees among different species; there was little difference in growth strain for the same height with different directions; 2） E. cloeziana, a new species developed for solid wood products, had the lowest growth strain level, but E. urophylla the highest in all five species tested; 3） three was no significant variation in growth strain measurement between standing trees and fallen trees in different species; 4） there was no significant difference in growth strain for tree height.
