摘要
本文采用二元回归方程建立柳杉平均高和平均胸径的模型，其复相关系数分别达０．９８和０．９５，经检验达极显著水平，同时应用Ｆｒｅｅｓｅ法ｘ２检验和误差估计表明上述２个模型均为较理想模型。
This paper adopted the binary
regression equations to set up the average height and average D. B.H models of Cryptomeria
fortunei.Their multiple correlation coefficients reached 0.98 and0.95, respectivelyand reached
extremely significant level through test. Meanwhile by means of applying the x2 test of
FreeseMethod and error estimation the above two models were relatively ideal ones.
