| Abstract: | In according with the growth and distribution of Cunninghamia lanceolata in Guizhou province,Cunninghamia lanceolata forest was divided into central area and general area with two model units respectively.In details,sample plots of each unit were set up to investigate,average tree diameters were selected for stem analysis,compound interest method was used to calculate volume growth rates of all kinds of the diameter & age class,and suitable equations with different matching ways were chosen to fit the model... |
