| 摘 要： | 在帽儿山地区，对落叶松林和白桦林2个可燃物类型的75块样地树种的胸径、树高、年龄等林分因子和地表可燃物的负荷量进行了野外调查和室内实验分析与计算，利用SPSS 11．5 for Windows统计软件和Matlab软件，分别对不同种类可燃物负荷量与林分因子进行分析，并建立了多元回归模型和人工神经网络模型。利用林分因子推算不同种类地表可燃物负荷量，取得了较为满意的结果。

| Abstract: | A study was conducted to analyse stand factors (crown cover, DBH, tree height, age) and surface fuel load of 75 plots for larch (Larix olgensis) forests and birch (Betula platyphylla) forests in Maoershan forest region based on the field investigation as well as the experiments indoors. Multi-regression model and artificial neural network model for estimating surface fuel load by stand factors were established under the support of Matlab and SPSS 11.5 for Windows. The result is quite good as expected. |
