通过对剖面各层中各种形态铁、锰的测定,研究了黄泥类水稻土剖面中铁、锰的分异特性。用淀积深度和淋淀比率表示的铁锰淋淀强度受水稻土发育程度、土体通透性及耕层铁、锰含量,尤其是耕层活性铁、锰含量的相对比率(Fe_o/Mn_o)的影响。由于淋淀比率会随着水稻土发育进程的加深而增大,犹如铁锰的淋淀强度一样,耕层的Fe_e/Mn_o比率可在一定程度上反映同类母质的黄泥类水稻上的发育程度。
Through the determination of various forms of iron and manganese in the various layers of the profile, the differentiation characteristics of iron and manganese in the yellow muddy paddy soil profile were studied. The intensity of Fe-Mn deposition expressed by deposition depth and deposition rate is influenced by the degree of paddy soil development, soil permeability, and the relative ratios of Fe and Mn contents, especially Fe and Mn, )Impact. As the ratio of leaching increased with the deepening of paddy soil development, just like the leaching intensity of iron-manganese, the ratio of Fe_e / Mn_o of top layer could reflect the development of yellow paddy with similar parent material to a certain extent .
