兴安落叶松林蓄积量与海拔的关系研究

摘要

This research have collected the continuous check the sixth review of 325 plots data of Daxing＇anling forest resources,and sorted out contingency table and analyzed it,moreover,did the chi-square test,residual analysis and log-linear model fitting.The res%收集大兴安岭森林资源连续清查第6次复查325块样地资料,将其整理成列联表并分析,对其进行卡方检验、剩余分析、对数线性模型拟合的结果表明,兴安落叶松林分蓄积呈现低、高海拔处低,中部海拔处林分蓄积量高的特点。
