Abstract: This paper established an integrated stand growth model of Mongolian oak（ISGMoak） using the data from 61 permanent sample plots measured in 1997 and 2007.ISGMoak is a group of nonlinear simultaneous equations.The method of nonlinear error-in-variable simultaneous equations is used to estimate the parameters of ISGMoak with the statistical software Forstat 2.0,so the parameter estimation of the group of correlated equations in ISGMoak is unbiased and the equations are compatible.Model validation using bootstrap method showed that both the average relative error and square error are less than 15 percent.The ISGMoak model can be used to simulate the stand growth with different values of site index,stand density and to draw stand density management diagram for decision making.
