The invention discloses an air floating vibration control system air spring stiffness self-balancing iteration identification method. Firstly, gravity load is applied to generate displacement by the aid of estimated stiffness values of air springs in an air floating vibration control system, displacement of air springs in an air floating platform is consistent with deformation of the air springs in a balanced state according to hypothesis, corresponding 'pseudo-stiffness' is obtained on the basis, 'pseudo-stiffness' values are compared with the estimated stiffness values, set discriminating conditions are met if two successive stiffness values are sufficiently approximate, the treatment process is converged and finished, the stiffness of the air springs is outputted as the 'pseudo-stiffness' values, otherwise, the estimated stiffness values of the air springs are modified into the 'pseudo-stiffness' values, and retreatment is performed until the air spring stiffness with the discriminating conditions in the a
