    By deploying the time-dependent Kohn-Sham (TDKS) scheme of the density functional theory, numerical simulations are performed on the photoionization of Ne atom and a triple-momentum-correlation (TMC) affected by intense extreme ultra-violet (XUV) laser pulses is found. The simulation results show the different characteristics of ionization from different orbital electrons. For strong XUV laser intensity, ionization undergoes mainly along the orbital direction (longitudinal direction) for the p-type orbits in Ne atom. By simulating the momenta components of different orbital electrons, it is unveiled that the parallel momenta of the orbital electrons are mutually correlated, and the perpendicular momenta are also mutually correlated, but not between them. These correlation relations are deciphered in the interplay between the orbital geometry, orbital orientation and laser polarization. The simulation results also show a profound ionization of the inner orbital electrons.
