  Using the determinant quantum Monte Carlo method, we investigate the
metal-insulator transitions induced by the stripe of charge density in an
interacting two-dimensional Dirac fermion system. The stripe will introduce the
transport anisotropy and insulating intermediate phase into the system,
accompanied by the change of band structure and a peak of density of states
around Fermi energy. In the case of strong correlation, stripe exhibits
competition with Coulomb repulsion through closing the energy gap and
disrupting the magnetic order, and finally drives the system in Mott insulating
phase back to the metallic state. Our results may provide a feasible way to
modify transport properties by setting charge stripes in experiments.
