In this paper, the new formulae of tree height curve and volume curve were derived from the theory of column buckling. They were applied to artificial Pine (Pinus sylvestris var.mongolica) and Larch (Larix principis rupprechtii). The results demonstrated that the new formulae were more effective and precise than conventional formulae of height curve and(More)
