摘要
本文研究分析了安徽10个土类,254个土壤样品的Mn、Fe、Cu三元素的含量,结果表明:成土母质和成土过程,对其有明显影响;另外,对Mn、Fe、Cu三元素在0～100cm土层中的迁移特征的分析表明,在土层中的迁移能力是Mn>Fe>Cu。土壤水分对Mn和Fe的迁移有明显作用,多为在土壤底层淀积;而Cu在土层中的分布,则多有表层积累,底层含量低的特征,并且土壤水分对其影响不明显。
Contents of Mn, Fe and Cu for 254 samples of 10 types of soil in Anhui province were analysed. The results showed that the soil-forming paraent rocks and the soil-forming process had obvious effects on the contents of 3 elements. In addition, the immigrating characteristics in 0—100 cm soil layer were studied for Mn, Fe and Cu with the followiing results: the order of immigrating ability was Mn>Fe>Cu; the water content had great effect on Mn's and Fe's immigration; Mn and Fe were mostly bottom layer illuvia, but the Cu's distribution in the soil had surface layer accmulation property and did not vary apparently with the water content.
