摘　　要：以广西南宁、玉林不同地点人工林江南油杉样地数据为基础,通过回归模型进行分析,回归方程分别为C=0.264D0.877、C=0.414D0.794,该回归方程能较好的描述其冠幅和胸径的相关关系,相关系数均在0.9以上,并在此基础上编制广西南宁、玉林江南油杉林分适宜经营密度表,为其人工林遗传育种、定量间伐提供数据参考。The regression equations in Nanning and Yulin were C=0.264D0.877and C=0.414D0.794by regression analysis based on plots data of Keteleeria cyclolepis, which could be used to describe its CW and DBH correlation between the first number-average above 0.9, then on this basis, the suitable management density table was drawn up to provide reference data for its plantation genetic breeding and quantitative thinning.
