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。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/Do, H = 32. 0925 - 244. 0503/DO, applied in measuring log volume with single entry volume table or two entry volume table together. It provided the references for forestry production.
