Six-parameter polarized BRDF Models were used to describe spectropolarimetric BRDF of cement board with experimental data. The nonlinear model parameters were obtained by genetic algorithm. The results show that the genetic algorithm has better performance and can get the nonlinear model parameters accurately. Through modeling analysis: cement board within visible spectrum shows the anisotropic characteristic, which is in consistency with the distribution regularity of polarized reflectance ratio factor of the target. In the region of the forward scattering, polarization are greatly influenced by observation geometry. Observing zenith Angle is smaller, the lower the degree of polarization, and with the increase of observing zenith Angle, polarization degree also increased gradually in the the principal plane. In back scattering range, there is also a local hot spot in the direction of the light source.
