| Abstract: | Based on random sample investigation method, it was measured the correlated models between diameter at breast height and tree height of Cunninghamia konishi, and the regressive analysis was used to study the correlated models between diameter at breast height and tree height. The results showed that optimal regressive equation was ob- tained as H = 1. 6928e~ ~037D ,the correlation coefficient was 0. 945. The residual standard deviation was 0. 106 ,which proved to be extremely significant and the equation error was only -0. 0153% with high precision. |
