| Abstract: | Based on the datum of the diameter at butt end (D.B.E),the diameter breast-height (D.B.H), the height and timber growing stocks of three tree species, Tugsa chinensis,Betula albo-sinensis and Sorbus hupehensis,authors built the timber growing stocks assessing models with tree diameter at butt end,having high correlation coefficient, and they could be applied in the forest resource management and forest ecosystem research. |
