We investigate the parton distribution functions (PDFs) of the pion and thekaon by combining quantum chromodynamics (QCD) evolution with the basis lightfront quantization. The initial PDFs result from the light front wave functionsobtained by diagonalizing the effective Hamiltonian consisting of theholographic QCD confinement potential, a complementary longitudinal confinementpotential, and the color-singlet Nambu--Jona-Lasinio interactions. Thevalence-quark PDF of the pion, after QCD evolution, is consistent with theresult from the E-0615 experiment at Fermilab. Meanwhile, the pion structurefunction calculated from the PDFs agrees with the ZEUS and the H1 experimentsat DESY-HERA for large $x$. Additionally, the ratio of the up quark PDF of thekaon to that of the pion is in agreement with the NA-003 experiment at CERN. Wealso present the cross section for the pion-nucleus induced Drell-Yan processwith the obtained pion PDFs supplemented by the PDFs of the target nuclei.
