摘要
以大兴安岭南段山地近40年来营造的针叶树人工林地为研究对象,采用典型抽样获得了169个样地林分和立地条件资料,将林木生长指标与立地因子指标结合应用,用统计分析方法,划分出4个造林立地类型组,39个造林立地类型。
Taking the needle - leaved plantation land planted for nearly 40 years in the mountain land in the south of the Greater Xing＇an Mountains as an object of study, the materials of stand and site condition of 169 plots have been ob- tained by use of typical sampling.
