【目的】通过建立含立地类型哑变量的湖南省金洞林场闽楠人工林单木树高曲线模型,为湖南省金洞林场闽楠人工林的目标树经营和生长预估提供理论依据。【方法】以湖南省金洞林场为研究区域,基于18块闽楠人工林固定样地2019年调查数据,选取了11个具有代表性的树高曲线模型对闽楠人工林树高-胸径关系进行了拟合,从中筛选出了拟合效果最好的模型作为构建哑变量模型的基础模型;通过对18块固定样地进行立地因子调查,采用数量化方法Ⅰ,以各林分的平均木优势高为因变量,立地因子为自变量,对立地因子进行评价,得到影响显著的立地因子,并通过划分等级和聚类分析来划分立地类型;将立地类型做为哑变量添加到基...

【Objective】Height-diameter model of individual-tree of Phoebe bournei plantation in Jindong forest farm based on dummy variable was established, which contains the dummy variable of site type. It provides the theoretical basis for the target tree management and growth prediction of Phoebe bournei plantation in Jindong forest farm of Hunan province.【Method】Taking Jindong forest farm as the research area, based on the survey data of 18 fixed sample plots of Phoebe bournei plantation in 2019, 11 representative tree height DBH models were selec...
