Ab initio studies of the magnetism and electron structure in LaMnO3 are reported in this paper.we find that when the Jahn Teller(JT) distortion is inexistent,the orbital ordering hardly happened even if add large coulomb exclude energy(Ueff).But when JT distortion arise,the orbital ordering is arising,and add Ueff can make the ordering more clear.
