摘    要:本文针对1985年及1992年森林资源二类调查资料,采用列联表方法,对毛竹林立竹密度与海拔及林分平均胸径对毛竹林分布的影响进行卡方检验、剩余分析和log-线性模型拟合,得出:闽北毛竹林密度多在1800株/hm2以下,胸径为第四级(8cm)以下,海拔最适分布区为400-1000m;现实毛竹林密度及平均胸径偏低,应提高毛竹林经营水平,促使林分达到合理结构以实现速生丰产的目标。

关 键 词:毛竹林,列联表,立竹密度,海拔,平均胸径

Abstract:The studies demonstrated that(1)most of the densities of Phyllostachys Pubescens forests were un-der 1800 bamboos/hm2 in North Fujian,their dbh was under Class Four(8cm)and the optimal altitude dis-tribution area was between 400m and 1000m,And(2)the actual densities and the average dbh of Ph.puhescens forests were on the low side.The level of managing Ph.pubescens forests should be raised to pro-mote the stands to reach reasonable structures ln order to realize the fast growing and high yield target
Keywords:Phyllostachys    pubescens forests  contingency table  standing bamboo densities  altitude  average dbh
