摘  要:
Buongiorno and Michie's growth matrix model plays an important role in the studying of development and management of unevenaged forest stands. Efficient estimation of the growth matrix parameters is the precondition of the use of the model. In this paper, a new method is employed simply using the diameter growth to estimate the transition probability of the matrix model. It is shown that this algorithm has the advantage of being more simple and precise than the others used before, and is an effcetive method for estimating the matrix model when the conditions premit.
