In this paper, we investigate the stabilities of g-frames and g-Riesz bases under the operator perturbation. Firstly, we provide several conditions of the operator perturbation for a g-frame and a g-Riesz basis by using a bounded linear operator T on H. Also, we give some characterization of g-Riesz bases and g-frames with respect to frame operators.
