The photon localization in disordered two-dimensional photonic crystal is studied by use of multiple-scattering method. The disorder degree can be controlled by adjusting the random rotating angle of the square cell. It is found that the transmission in the band decreases and that in the gap increases as the disorder degree increases, and localization induced by disorder will spread from the band gap edge to the band center and the gap center. Moreover, the mean transmission of the band will decrease exponentially with disorder increasing.
