森林可燃物参数与林分特征关系

A relation between forest combustible parameters and stand characteristics

森林地被可燃物是引起森林火灾的重要原因,掌握森林地被可燃物的载量分布,对森林火灾的预防有着十分重要的意义。但森林地被可燃物载量数据的获得是比较困难的,运用Spss11.0forwin dows统计软件系统,对兴安落叶松林和杨桦林的林分因子和各类地被可燃物载量进行后向逐步线性回归分析,建立了一套数学模型,取得了较为满意的结果,从而可以通过林分因子推算各类地被可燃物载量。

Forest surface combustible is a important reason of arousing forest fire. Preventing forest fire is dependent on having load distribution of surface combustible in hand. But it is difficult to gain the load of forest surface combustible. So a set of model were set up between stand factors and load of every surface combustible by applying backward step by step multiple regression, and the result is satisfactory. So through stand factors, the load of every surface combustible may be calculated by using the models.
