| Abstract: | 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 and 0.9827694 for breast-height diameter. |
