| 摘 要： | 本文利用人工神经网络建模技术,以河南农业大学三区内毛白杨人工林99株的断面积平均直径和树高资料为基础,研建了树高曲线人工神经网络BP模型和幂函数模型。通过两个函数模型的比较表明:人工神经网络建模技术精度高、误差小,具有很强的泛化能力。在用幂函数拟合较差的情况下,人工神经网络也取得很高的精度,其拟合效果具有明显的优势。

| Abstract: | Based on 99 populus tomemtosa’s basal area and tree height materials in NO.3 district of Henan Agricultural University,the paper,utilizing modeling technology of the artificial neural network,carried on t the tree height-diameter model of the BP artificial neural network model and exponential function model..Between the two functions: the precision of the rtificial neural network model is better than the exponential function model,the aberration is less.While the exponential function fitting curve worse,the artificial neural network makes very high precision too.It has obvious advantage of fitting curve. |
