摘　　要：在吉林省延边天然赤松集中分布地区,采用随机抽样方法,测定了384株天然赤松样木的树高与胸径,通过回归分析方法研究了树高与胸径的相关模型,拟合了其最佳回归方程为H=16.9878e-5.276 4/D,经显著性检验,呈极显著水平,回归方程系统误差为0.014 9%.In the region of natural red pine＇ s distribution in Yanbian of Jilin province, the method of random sample had measured the data on tree height and diameter at breast height of 384 natural red pines. And then regressive analysis was used to study correlated models of the tree height and diameter at breast height. As a result, optimal regressive equation was obtained as H =16.987 8e^-5 276 4/D , which proved to be extremely significant and the equation error only 0. 014 9%
