摘要
提出直接用直径生长量来估计异龄林林分生长矩阵中的转移概率。该法具有计算简单和精度高的优点,在条件允许的情况下,不失为一种非常有效的参数估计方法。
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.
