| Abstract: | By using Richards equation.the growthmodel of Chinese fir plantation was built,while input variates tvers stand age, site indexes and stand desities. and output were totle basal area of stands and even diameters al breast height, error analysis showed that the model was fit. Based on it. foe variable-density yield table for Chinese fir Plantation was drown up. |
