Abstract: On the basis of Budyko's zero-dimensional model, a nonlinear zero-dimensional climate model with many parameters is advanced, and the effect of radiation rate, reflection rate and transparency of atmosphere on the action of climate system are discussed. Having considered the effect of different parameters, some conclusions of analysis are presented as follows: The limits among parameters restrict the equilibrium state and stability of system. The increase of solar radiation, optics thickness, and cloud are all the important factors which might lead to changes of climate. The increase of planetary reflection, radiating rate of atmosphere and Carbon dioxide would benefit the stability of climate, so the increase of Carbon dioxide would be an advantageous factor to the stability of climate. Linear negative feedback of reflection might make the globe temperature decrease comparing with Budyko' and nonlinear feedback would restrain the positive feedback of Carbon dioxide,vapor and cloud.
