Based on Pinus massoniana plot data of sixth and seventh continuous forest inventories in Guangxi Province,the analysis results of individual tree and stand volume growth rate model under different origins are as follows:logarithmic function model Y=a+bln(X) and power function model Y=a×Xb respectively as individual tree and stand under different origins of optimal volume growth rate model .In the growth period of young pinus massoniana forest,volume growth rate of the artificial forest is greater than the natural forest and has large varied amplitude,at the later growth stage,volume growth rate of the natural forest is greater than the artificial forest and has stationary varied amplitude.The difference of volume growth rate between different origins of individual tree is significant,the difference between different origins of stand is not obvious.
