    摘要:

    本文对贵州省六个主要土类有代表性的典型土壤68个剖面,204个土样中的稀土元素含量及分布进行研究,结果表明:贵州省典型土壤中稀土元素总量(264.44μg/g)高于全国土壤平均含量(195.7μg/g);各土类稀土元素的丰度都遵守Oddo-Harkins法则,Ce元素富集明显。贵州典型土壤中轻稀土元素含量(199.01μg/g)亦高于全国土壤,属典型的轻稀土土壤类型;石灰土中稀土各元素含量大于其它土类。同时该文还探讨了影响土壤稀土含量的主要因素。

    Abstract:

    The content and distribution characteristics of rare earth elements of 204 soil samples in 68 typical soil profiles of six main soils in Guizhou Province were studied.Results showed that the rare earth element conent (264.44μg/g) in the typical soils of Guizhou Province are higher than their average content (195.7μg/g) in soils of some other areas of China. Also such is the case of light rare earth elements contents (199.1μg/g). It may be considered that these soils belong to a typical soil type containing more light rare earth elements. The rare earth element in all of these typical soils in Guizhou Province obeyed the rule of Oddo-Harkins. Element Ce enriched in these typical soils. The contents of the rare earth elements are the highest in the calcareous soil. In additon, the main factors which affected the content of rare earth elements are also studied.
