摘要
通过理论分析与实践验证提出一种新的林分直径分布预测方法Ｇ—ＰＲＭ．其基本思想是：用著名种群模型—Ｇｏｍｐｅｒｔｚ方程来表示林分直径分布；采用两点回收、差分还原的途径实现林分结构的预测．将该模型应用于闽北杉木人工林直径预测，其预估林分直径分布的合格率为７８％．
Combined theoretical analysis with actual tests, a new method (G-PRM) for stand diameter
distribution is presented. The main idea of the method is generalised as follows: stand
diameter distribution is expressed by means of the famous Gompertz equation interpopulation
dynamic model; the prediction can be made by the two-point recovery and difference
restoration; the model is used to predict the diameter distribution of Chinese fir plantation in the
north of Fujian Province with its acceptable rate being 78%.
