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… CONTINUE READING
