落叶松、樟子松、白桦根径与胸径关系研究

Study on the relationship between the root diameter and diameter at breast height of larch,pinus sylvestris and white birch

利用5994株样木,对内蒙古大兴安岭国有林区落叶松、樟子松、白桦的胸径与根径的关系进行了分析研究,在研究中分别以立地区域、径阶对胸径与根径的关系进行了拟合,为生产实践提供理论依据。

In this paper, the relationship between the root diameter and diameter at breast height of larch, pinus sylvestris and birch in the state-owned forests in Daxinganling of Inner Mongolia was analyzed and studied. In the study, the relation between root diameter and diameter at breast height was matched in order to provide theoretical basis for production practice.
