| Abstract: | By using the modified method of growth increment, in this article the competitive increment models of individual tree for Chinese fir have been developed, the estimate models of diameter growth percentage for Chinese fir have been obtained in Huitong, Human. On the basis of the relationship between height, volume and diameter, the models of height and volume growth percentage were derived. |
