This paper established an integrated stand growth model of Mongolian oak (ISGM_oak) using the data from 61 permanent sample plots measured in 1997 and 2007. ISGM_ oak is a group of nonlinear simultaneous equations. The method of nonlinear error-in-variable simultaneous equations is used to estimate the parameters of ISGM_ oak with the statistical software Forstat 2.0, so the parameter estimation of the group of correlated equations in ISGM _oak 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 ISGM_ oak 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.
