    Abstract:

    Migration of Cu and Zn in soils derived from basalt in Zhejiang Province occurs in their soil forming process. The amount of migration of Cu is larger than that of Zn. However the influence of the migration of these elements on their total contents is less than that of the geochemical difference of parent riaterials. Cu and Zn contents in the surface soil are higher than those in subsoil, and those in the soils with a higher altitute are higher than those in the soils with a lower altitute. The effect of pH is insignificant.The ratio of amorphous Cu to total Cu in the soils with similar allitic process increases with the increase of the altitute at which the soils are located, i.e. there is significant difference in the ratio among the red earths, yellow-red earths and yellow earth. However, the content of amorphous Cu tends to be decreased with the intensification of weathering and eluviation proceses. All these may be used as factors for soil classification and evaluation of soil fertility.
