In this research, the surpassing collectivity theory was adopted to compile the growth rate model of the forest stand average breast diameter of the main tree groups in east area of Liaoning province; and based on the results of the second class investigation of foreslry resources in 2005, the model covered growth levels of eight tree groups in different location and site environment of seven cit- ies and thirty-one counties in east area of Liaoning province. It conslructed four simulative formulas, and the growth rote model of the forest stand average breast diameter of every tree group was selected through fitting, optimization and result aecuracy check.
