Abstract: Based on the retest data of young ,half-mature and near-mature Cunningharnia lanceolata ecological forest in Fushoushan National Forest Park of Hunan,and the correlation among Hegyi,V Hegyi,W_V_Hegyi, the three competition index, the W_V_Hegyi which was the strongest one was chosed to construct individual competition tree model. According to the above, the weighted average tree height as the weight of DBH growth,then rebuilded the individual tree model. And quantitative analysis was carried out on the competition index of the diameter class,and the regression analysis method was used to build prediction model of diameter class competition index and diameter class growth model. The diameter class growth model was constructed based on the weight DBH growth and W_V_Hegyi competition index,in order to provida new way for simulation from individual to stand.
