中文摘要：

以海南岛发育典型的砖红壤为研究对象,对其不同剖面微量元素的组成特征和分异变化规律进行研究,发现不同剖面微量元素的含量变化趋势具有一定的相似性,土壤母质是决定砖红壤微量元素含量和分异的主要原因;而人类活动对砖红壤剖面中的部分微量元素的含量与分异具有一定影响,导致少量Cr、As、Pb等有害外源微量元素进入土壤并趋于在土壤的浅层富集.

英文摘要：

This paper takes typically developed latosol in Hainan island as research object. The study on content features of the trace elements of different soils from different latosol profiles indicated that the trace elements of soils show a similar variation trend, the contents of the trace elements of the soils and their change tendency are determined by the parent material of the soils. On the other hand, some contents and change of latosol profiles have been impacted by human activity, the trace elements of the soils such as Cr、As、Pb can be enriched in the lower layer of the latosol profiles because of human activities.
