摘 要: 对海南岛南部耕地土壤中典型的12个土壤剖面微量元素的组成特征进行研究,发现12个剖面微量元素含量变化趋势具有一定的相似性,其中Co、Mo的平均含量大多高于中国土壤平均值和世界土壤平均值.各剖面微量元素含量的垂向变化规律显示,研究区土壤中微量元素含量及其垂直变化从根本上取决于土壤母质的特征.人类活动也可能导致少量Cu、Zn等元素在土壤的浅层富集. The distribution of the trace elements in eluvial horizons, illuvial horizons and parent material horizons of 12 agricultural soil profiles in Sanya City was studied. For most of trace elements except Co and Mo, the contents of trace elements in different horizons are lower than its average contents in the soils of the world. The study on content features of the trace elements of different soils from different agricultural soils 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 agricultural soils profiles have been impacted by human activity.
