The propagation property of ion-acoustic soliton in a weakly inhomogeneous plasma caused by ionization is studied. Finite ion temperature and ion-neutral collisions are considered the self consistent, stationary distribution N(x), V(x) and the corresponding soliton solution are obtained, numerical results of soliton amplitude, speed and width dependent on position are given, which are reasonable and consistent with experiments.
