| 摘 要： | 本文研究了淹水条件下水稻土的两种主要母土的元素活化迁移规律及其地球化学特征。结果表明，淹水条件下淋溶迁移元素来源于不同的母体；铁，锰，钙，镁等元素的活化作用加强，迁移能力增加，元素的迁移序列中锰的迁移能力已接近钙，镁等活泼元素；两种土壤中元素的迁移序列不同。性质相似的元素在迁移过程中具有相似的行为，相互之间有很好的相关性，因而在统计区分中位置靠近。引起元素在土壤中活化迁移的过程包括还原，重碳酸化，

| Abstract: | Activation and migration and their geochemical characteristics of elements under simulated submerged condition were studied, with red soils and fluvo-aquic soils as substrates. The results showed that leached elements came from different soil parts. The activities of Fe, Pvln, Ca and Mg were strengthened, and their migrating abilities increased. Mieration coefficient of Mn was nearly as large as that of Ca and Mg. The orders of elements migration in the two soils were different, in the red soil, being the order of Ca>Mn>Fe>Mg, Na>K>Si, P>Al, but Ca>Mg>Mn>Na>K, Fe>P>Si>Al in the fluvo-aquic soils. |
