Based on the isospin-dependent Boltzmann-Uehling-Uhlenbeck transport model and the scaling model according to nucleon effective mass, effects of elastic and inelastic NN scattering cross sections on {pi}{sup -}/{pi}{sup +} in the neutron-rich reaction of {sup 48}Ca+{sup 48}Ca at a beam energy of 400 MeV/nucleon are studied. It is found that cross-section effects of both NN elastic and inelastic scatterings affect {Delta}{sub 1232}, {pi}{sup -} and {pi}{sup +} production, as well as the value of {pi}{sup -}/{pi}{sup +}.
