The heavy-ion fusion reactions induced by neutron-rich nuclei areinvestigated with the improved quantum molecular dynamics (ImQMD) model. With asubtle consideration of the neutron skin thickness of nuclei and the symmetrypotential, the stability of nuclei and the fusion excitation functions ofheavy-ion fusion reactions $^{16}$O+$^{76}$Ge, $^{16}$O+$^{154}$Sm,$^{40}$Ca+$^{96}$Zr and $^{132}$Sn+$^{40}$Ca are systematically studied. Thefusion cross sections of these reactions at energies around the Coulomb barriercan be well reproduced by using the ImQMD model. The corresponding slopeparameter of the symmetry energy adopted in the calculations is $L \approx 78$MeV and the surface energy coefficient is $g_{\rm sur}=18\pm 1.5$ MeVfm$^2$. Inaddition, it is found that the surface-symmetry term significantly influencesthe fusion cross sections of neutron-rich fusion systems. For sub-barrierfusion, the dynamical fluctuations in the densities of the reaction partnersand the enhanced surface diffuseness at neck side result in the lowering of thefusion barrier.
