The flavor-asymmetry in the light-quark sea of the nucleon can be obtained from the contributions of unbroken sea quark distributions. We employ the polarized valon model in based on Jacobi polynomial approach and extract the flavor-broken light sea quark distributions which are modeled with the help of a Pauli-blocking ansatz. Our results for {delta}u, {delta}d, {delta}u-bar, {delta}d-bar and {delta}s-bar are in good agreement with recent experimental data for polarized parton distribution from HERMES experimental group and also with GRSV model.
