Based on the propagation law of partially coherent light, the longdistance pro pagation of the spatially partially coherent polychromatic light through the atm osphere is studied. It is shown that the atmospheric turbulence gives rise to sp ectral shift and to beam spreading of spatially partially coherent polychromatic-light whether the scaling law is satisfied or not. The influence of turbulence on beam spreading of the spatially partially coherent polychromatic light is sma ller than that of spatially fully coherent polychromatic light. However, the inf luence of bandwidth on the intensity distribution is relatively small.
