摘　　要：通过模拟试验对新疆阿尔泰山灰色森林土壤中Mn的迁移特征进行了初步研究。试验结果表明：含Mn的移动物质沿土柱的迁移深度因处理液体不同而不同，可以排列为：EDTA标液〉富哩酸溶液〉树叶浸提液〉地表水〉蒸馏水。EDTA标液在11～12cm深度的迁移速度可达12．1cm／min，迁移最深达23cm。土层中氧化-还原状况的交替出现能促进Mn的迁移。富哩酸-Mn形态Mn的迁移明显高于MnSO4形态Mn。Migration features of Mn-contained compounds in different forms of grey forest soil from Altai of Xinjiang has been investigated preliminary through simulation experiments. The results show that speed and depth of Mn-eontained compounds migration along earth column vary with the different liquid treatment, they can be ranked as follows.. EDTA standard liquid〉Fa liquid〉tree leaf extracting liquid〉surface water〉 distilled water. The migration speed of EDTA standard liquid at 10 meter depth can reach 12.1 cm/min, reach the maximum depth 23 cm. In the soil layer, the alternative oxidation and reduction state can also promote migration of Mn. The migration of Mn in Fa-Mn is obviously higher than that of the Mn of MnSO4.
