Various soil samples were collected from 12 non-cultivated soil profiles in western Hainan Province,and both the REE compositional features of these samples and their spatial variations in these non-cultivated soil profiles were analyzed.
对海南岛西部发育典型的12个非农业土壤剖面REE的组成特征及其纵向变化规律进行研究发现,区内非农业土壤剖面不同层位之间的稀土元素具有一定的继承性,风化成土的基岩奠定了土壤中稀土元素的初始含量及土壤中呈现的LREE富集与Eu亏损的特点,而成土过程中稀土元素分异作用则进一步加剧土壤中LREE的富集和Eu亏损,土壤剖面浅部的氧化和水解作用致使Ce在浅层土壤中的富集,并导致由剖面深部至浅部,Ce呈现出正异常增大之趋势。
