The effect of impurities on a spin-density wave (SDW) state in one-dimensional interacting electron systems is investigated by applying a phase u-epresentation and thetheory of the weak impurity pinning. With the help of numerical simulation, it isshown that the pinned SDW is characterized by both a rapidly varying phase variableof the spin-density fluctuation and a slowly varying phase variable of the charge-den-sity fluctuation. Based on this, the critical condition on the magnitude of interactionsfor Iocalization-delocalization transition is determined by use of the self-consistentharmonic approximation.
