Abstract: Richard,Logistic,Korf,Mitscherlich,Schumacher,Weibull equations were used to simulate individual tree height growth of Pinus tabulaeformis plantation with different site indexes.The result showed that simulative precision of three parameters growth equations(Logistic,Weibull,Richard,Korf)were similar,and were significantly higher than those of the two parameters equation(Mitscherlich,Schumacher equation);Effect of site indexes on the progressive line parameters and shape parameters of the equation was significant.Individual tree height growth model of Pinus tabulaeformis plantations was constructed with the site indexes.The best forecast equation was the Logistic equation. Using some data of Pinus tabulaeformis plantation plot that are not used for building models to test,the result showed that the measured values and simulated values of height had no significant difference(p=0.6213>0.05).Therefore,the equation was able to predict accurately height growth of Pinus tabulaeformis plantation,and provide an important reference for Pinus tabulaeformis plantation management.

Key words: Pinus tabulaeformis plantation, theoretical growth equation, height growth model
