Abstract: In order to study the growth relation model between tree height and DBH of Cyclobalanopsis glauca plantation, Cyclobalanopsis glauca plantation in Jiufeng National Forest Park was taken as the research object. 484 groups of tree height and DBH data were divided into modeling data and test data, and 10 common tree height curve models were selected to fit the modeling data respectively. The results showed that all the 10 tree height curve models reached extremely significant level（P＜0.01）, among which the quadratic curve model had the smallest SSE and RMSE and the largest R~2, which accorded with the screening principle of the optimal model. The residual analysis of the optimal model showed no significant difference, and there was no significant difference between the predicted and measured tree height values obtained by substituting test data into the optimal model（Sig.= 0.159＞0.05）. The conclusion showed that the quadratic curve model could effectively predicted the height of Cyclobalanopsis glauca plantation.
