摘要
对巨尾桉不同造林密度的林分生长指标进行了分析,结果表明:巨尾桉不同造林密度对林木胸径、树高及单株材积都有影响,但树高差异不大。不同造林密度对巨尾桉胸径和单株材积的影响为:随着密度的增大,林分平均胸径和单株材积变小,当造林密度为1110株/hm^2时,平均胸径和单株材积最大;当造林密度为2500株/hm^2时,林分的蓄积量最大。
The results showed that afforestation density had different afforestation density on Eucalyptus grandis×E.urophylla by analyzing their growth indicates.But tree height was not big difference.The effects of different afforestation densities on DBH and individual plant volume were as follows:with the increase of density,the average DBH and plant volume decreased.When the afforestation density was 1110plants/hm^2,there was the maximum average diameter of DBH and plant volume.However,when the afforestation density was 2500/hm^2,there was the largest stand volume.
