Massive lepton pair production in high energy hadronic collisions is studied in the framework of perturbative QCD. As for the origin of lepton pairs, the Drell-Yan process and the heavy quark pair production followed by the decay into leptons are taken into account. A model is proposed to reproduce existing experimental data. In the same model, predictions are presented for the massive lepton pair continuum spectrum at future accelerator energies. The effect of scaling violation, form of gluon distribution and Z^0 boson are discussed in detail. In the region where M≪√<s>, the cross section of lepton pair production by heavy quark pair is found to dominate over that by the Drell-Yan mechanism. This result indicates a possibility for observing a clean signal of gluon-gluon hard collisions in future high energy accelerators.
