摘 要：We report a detailed investigation of the bulk motions of the nearby Galactic stellar disk,based on a sample of 0.57 million FGK dwarfs selected from LSS-GAC *** construct a three-dimensional map of bulk motions of the Galactic disk from the solar vicinity out to kpc with a spatial resolution of50 *** values of the
