Abstract：
A simple and effective scheme for improving the lattice Hamiltonian in 1+1 dimensional QCD is given. The large Nc behavior of the vector meson mass in the chiral limit is studied by using this improved scheme. This numerical result is consistent with the analytical strong coupling result.
