吉林中部蒙古栎林心材与边材的生长特征
Growth Characteristics of Heartwood and Sapwood in Quercus Mongolica Forest in Central Jilin Province
[目的]探讨边材宽度、心材半径、心、边材面积与胸径树高的变化规律,分析建立蒙古栎林心边材生长发育模型,以期为该地区科学经营与利用森林提供基础数据。[方法]本文以吉林省三湖自然保护区桃山林场的天然蒙古栎林为对象,利用Haglof树木生长锥钻取样木树芯 46 个,测定东、西、南、北四个方向的边材宽度、树皮厚度、去皮半径、心材半径,拟合边材宽度、心材半径、边材面积、心材面积与胸径树高的回归方程,研究蒙古栎心材与边材生长特征。[结果]南北边材宽度、心材半…查看全部>>
