【摘要】 本文采用仪器中子活化分析法（ⅢAA）测定贵州一些土壤中的稀土元素含量,据此研究其分布的影响。结果表明:尽管土壤及其母质类型不同,但是其稀土元素分布还大体上保持母质中的分布模式特征。在风化和成土过程中,存在特殊稀土的活化分异现象。更多还原

【Abstract】 The content of rare earth element of soil in Guizhou was determined by means of instrumental neutron activation analysis in this paper. According to the result, the distributional character of the REE and the effect of weathenng process as well as pedogenesis are studied. It is indicated that even though there are different types of soil and their bedrocks, the distribution still keeps the similar model of the REE in bedrock. In the process of weathering and pedogenesis,there exists a phenomenon of differentiation by activation of special REE.更多还原
