The pseudorapidity dependence of anisotropic flows v1, v2, v3and v4of charged hadrons in heavy-ion collisions at the relativistic heavy-ion collider is studied in a multi-phase transport model. We find that while the string melting scenario, in which hadrons that are expected to be formed from initial strings are converted to their valence quarks and antiquarks, can explain the measured pT-dependence of v2and v4of charged hadrons at midrapidity with a parton scattering cross section of about 10 mb, the scenario without string melting reproduces better the recent data on v1and v2of charged hadrons at large pseudorapidity in Au+Au collisions at s=200AGeV. Our results thus suggest that a partonic matter is formed during early stage of relativistic heavy-ion collisions only around midrapidity and that strings remain dominant at large rapidities. The pT-dependence of v1, v2, v3and v4for charged hadrons at forward pseudorapidity is also predicted, and we find that while v1and v2are appreciable at large pseudorapidity the higher-order anisotropic flows v3and v4are essentially zero.
