摘要
本文从林分生长和林分密度间的关系,探讨了林分平均胸径的生长,并用于内蒙古大兴安岭地区收集的兴安落叶松(Larix gmelinii Rupr.)地位指数18m的65块标准地和130株解析木数据。根据林分平均胸径生长方程和其他林分生长因子的相关规律,探讨编制兴安落叶松天然林可变密度收获表的方法。
Growth of average stand DBH is discussed based on relationship between stand growth and stand density. Growth equation of average stand DBH is fitted with data of 65 plots and 130 stem analyses of site index 8 meters of Dahurian larix collected from Daxinanlin in Neimenggu. Variable density yield tables of Dahurian larix are constructed based on growth equation of average stand DBH and relationship between average stand DBH and the other stand attributes.
