The large-scale sidereal anisotropy of cosmic rays is observed by Tibet air shower array in the northern hemisphere. Energy dependence of the cosmic-ray anisotropy from 300 TeV to 1 PeV is analysed. We find that the anisotropy maps above 300 TeV are distinct from that at the multi-TeV energy band. The spatial distribution of the GCR intensity of an excess and a deficit is observed in the 1 PeV anisotropy map. All these results may further our understanding of the origin and propagation of GCRs.
