%X The paper deduced movement and wave equation of seismic wave field in constant Q viscoelastic media using the method of Pseudo-spectral, and carried on forward modeling, the modeling result is the same with the one of other modeling ways. But compared with other methods, using the method of Pseudo-spectral is not only simple and direct, easier to comprehension; the method becomes compact and universal when compared with the former methods. So we say that we can absolutely avoid unnecessary and bothering process in mathematic deducibility if making full use of the method of Pseudo-spectral in more complex viscoelastic media, we can get wave equation when directly replacing with two kinds of relaxation modules.
