| 摘 要： | 根据巨尾桉人工林样木的地径D0、胸径D及树高H观测数据,采用多模型选优法和逐步回归法求解方程,经分析对比后分别建立了地径与胸径、地径与树高相关的2个数学模型:lnD=3.7275-18.6673/D0;H=32.0925-244.050 3/D0。应用这2个模型,配合一元材积表或二元材积表就可测定被伐木的材积。

| Abstract: | Based on the investigation on the ground diameter(D0),diameter at breast height(D) and tree height(H) of sample trees of Eucalyptus urophylla×E.grandis plantation,multi models for selecting elite trees and progressive regression equation method were applied in establishing 2 maths models which responsed the correlation of ground diameter and DBH,ground diameter and height.The 2 models were lnD=3.7275-18.6673/D0,H=32.0925-244.0503/D0,applied in measuring log volume with single entry volume table or two entry volume table together.It provided the references for forestry production. |
