Using the model of the nonlinear Compton scattering and FDTD algorithm, influences on the photonic band gap characteristic of the uniform plasma photonic crystals were studied, induced by the multiphoton nonlinear Compton scattering. A new mechanism of photon band gap induced by incident light and scattered light was given out, and the electromagnetic wave equations were amended. The results show that attenuating of the electromagnetic wave peal value is faster after the Compton scattering, prohibit band gap widths of electromagnetic wave transmission chart nearly are not changed along with the increase of the plasma density, central frequencies are clearly moved to the high frequency directions, the upward crest values have bigger increase numbers, and the downward crest values of the reflected chart have bigger decrease numbers. The prohibit band gap widths of the transmission chart have clear decrease numbers along with the increases of the plasma temperature, the upward crest values have even little decrease numbers, and the transmission energy have littler decrease numbers too. The photon prohibit band gap numbers are increased along with the increases of the dielectric constant ratio value in the two mediums, and the band gap intervals are clearly decreased.
