The eluviation-illuviation and movement regular patterns of different forms of iron and manganese in the acid sulfate soils were studied. The various iron and manganese oxides in the soils were in an inter connected and interactive eqlibrium systrm and an aging and activating contradictory entity. The soil acidity controlled the transformation of different forms of iron and mandanese. The acid sulfate soils had a special regular pattern of iron and manganese transformation, since they are very acid and contain a more O.M. Form the surface layer to the ground layer of the soil profiles, the pH value became lower, the ratio of amorphous iron/free iron became bigger and the ratio of crystalline iron/amorphous iron becamr smaller, along with the development of the soil profiles. As compared with iron, manganese was more sensitive to the change of redoxing condition, and the contents of total and easily reducible manganese were rather low in the acid sulfate soils.
