简介了人工神经网络及使用方法，建立了单木树高与胸径生长的三层前馈反向传播神经网络模型（即ＢＰ模型），并对单木树高、胸径生长的ＢＰ模型与Ｒｉｃｈａｒｄｓ函数进行了比较。

This article builds a model of three-level feed-toward back-propagation neural network to simulate the tree breast-height diameter and tree-height growth. By using this BP model and the Richards function to treat the original data,the accuracy could be increased obviously. The correlation ratios are up to 0.9939298 and 0.9896239 for treeheight; 0.9882061 a...
