【Abstract】 The characteristics of the form distribution of Fe and Mn in soils of Altai Mountains were studied by the fractionation method. The exchangeable Fe, weak acid soluble Fe, oxides bound Fe, and organic matter bound Fe changed increasingly and residual Fe decreasingly, with increasing elevation, following the order of calcic brown soil, castanozem, chernozem, dark brown forest soil, subalpine meadow soil and alpine meadow soil. The form characteristics of Fe in Altai Mountains soils can be divided into two types: dry type and moist type. The Mn form distribution in soils was more complicated than Fe in soils. It was affected by climate, vegetation etc. especially by microbes, the differences of the behavior between Fe and Mn in soils, factors affecting on it, and its genetic significance were discussed.更多还原
