  Recently studies of the dipole anisotropy in the arrival directions of
Galactic cosmic rays indicate that the TeV-PeV dipole anisotropy amplitude is
not described by a simple power law, moreover a rapid phase change exists at an
energy of $0.1\sim0.3$ PeV. In this work we argue that the dipole anisotropy
amplitude and phase evolution with energies can be reproduced under the
spatially-dependent propagation scenario with a nearby single source added. Our
results indicate a nearby single source have significant influence to the
cosmic ray gradient below $0.1\sim0.3$ PeV under the spatially-dependent
propagation scenario, which leads the dipole anisotropy phase change at this
energy region. The dipole anisotropy amplitude of the galactic cosmic rays can
also be maintained at a lower level, which are consistent with observations by
underground muons and air shower experiments.
