基于ANN的栎类天然次生林林分直径分布研究

Study on Stand Diameter Distribution of Oak Natural Secondary Forest Based on ANN

利用宝天曼自然保护区栎类天然次生林32块标准地的调查数据,采用人工神经网络建模方法,以相对直径作输入向量,以株数累计频率作输出向量,在MATLAB软件中进行模型训练,建立人工神经网络模型。对主要树种建立的7个模型进行的精度分析表明,该模型能够很好地描述栎类天然次生林主要树种的直径分布。

Based on the data of the investigation on 32 standard plots of oak natural secondary forest in Baotianman Natural Reserve, with relative diameter as input vector and accumulated frequency of plant number as output vector, the artificial neural network modeling method was used to conduct model training in MATLAB software and establish the artificial neutral network model, The precision analysis on 7 models established by main tree species showed that this model could better describe the diameter distribution of main tree species in oak natural secondary forest.
