The invention relates to a layering method suitable for a shallow stratum layer of a sedimentation basin. The method successively comprises that 1) seismic waves are carried out the shallow stratum layer of the sedimentation basin, a dispersion curve of the seismic waves is extracted, and the density and longitudinal-wave speed of the stratum layer within a detection range are obtained via inversion; 2) the wave impedance parameter which is the product of the density (t/m<3>) and the longitudinal-wave speed (m/s) is obtained; and 3) the minimum value 1400-1600 and the maximum value 3400-3600 of the wave impedance parameter are selected, and contour lines are made every 500 units from low to high within the range from the minimum value to the maximum value to successively form a gravel-contained sandstone layer, a gravel-contained coarse sandstone layer, a gravel-contained mudstone layer and a mudstone layer. According to the method, the wave impedance parameter is the product of the density and the longitudinal-wave speed, and the performance of the stratum layer is divided according to different value ranges of the impedance parameter, thereby providing basis for predicting the coal position in a gulch-gold sandstone uranium mine.
