Nuclear deformations and density profiles of neutron-rich even-even Zr isotopes are investigated by using the Skyrme-Hartree-Fock-Bogoliubov method. Large quadrupole and hexadecapole deformations are predicted along with large enhancement of the total reaction cross sections at the neutron number $N=60–74$. Strong nuclear deformation starting at $N=60$ is induced by the occupation of the intruder orbit with the asymptotic quantum number $\left[n{n}_z\mathrm{\Lambda }\right]\mathrm{\Omega }=\left[550\right]1/2$ originating from the spherical $0h_{11/2}$ orbit. The deformation region is further enlarged from $N=72$ to 74 owing to the occupation of the next intruder orbit with $\left[530\right]1/2$ originating from the spherical $1f_{7/2}$ orbit. This characteristic nuclear deformation is crucially reflected in a systematic behavior of the nuclear radii and the density profiles near the nuclear surface.
