在成土过程中,铜和锌均有移动,迁移量铜大于锌,但这种作用小于母岩地球化学差异对总含量的影响。铜和锌的有效态含量,表土高于底土,海拔高处大于低处,pH值的影响作用并不显著。土壤中无定形铜含量与全铜量的比值,在富铝化程度相类似的土壤上随海拔升高而明显增大,即在红壤、黄红壤和黄壤之间有明显不同。无定形铜含量有随风化淋溶作用增强而降低的趋势。这些可作为土壤分类和肥力评价上的参考。
During the process of soil formation, both Cu and Zn moved, and the amount of Cu migrated was greater than that of Zn, but this effect was less than that of the difference of the geochemical contents of parent rocks. The effective content of Cu and Zn, surface soil is higher than the subsoil, altitude is greater than the low point, the effect of pH is not significant. The ratio of amorphous copper content to total copper content in soils increased significantly with increasing altitude in soils with similar levels of aluminization, ie, significantly different between red soil, yellow-red soil and yellow soil. Amorphous copper content with the role of weathering and leaching to enhance and reduce the trend. These can be used as a reference for soil classification and fertility evaluation.
