摘要:

对大兴安岭林区兴安落叶松林、樟子松林和白桦林3个可燃物类型的68块样地的郁闭度、胸径、树高、林龄等林分因子和地表可燃物(1h、10h、100h时滞可燃物和灌木)的载量进行了野外调查和室内实验分析与计算,应用Spss统计软件,对不同种类可燃物载量与林分因子进行回归分析,并建立了数学模型,利用林分因子来推算不同种类可燃物的载量,并取得较为满意的结果。

关键词: 林分因子, 可燃物载量, 大兴安岭林区

Abstract:

Based on the investigation of forest stand factors (crown cover, DBH, height, age) and surface fuel load (1 h, 10 h, 100 h dead fuels and brush) of 68 plots of Larix gmelinii, Pinus silvestris var. mongolica , and Betula platyphylla forests in Daxing'anling Forest Region, prediction of fuel load was made by using forest stand factors under the support of Spss. The result is quite good as expected.

Key words: forest stand factor, fuel load, Daxing'anling Forest Region
