| 摘 要： | Total and bioavailable concentrations of rare earth elements （REEs） in the latesol of Hainan Province, China, were measured by ICP-MS, and the distribution characteristics of REEs were discussed in various latesol profiles. The results show that the total concentrations of REEs were higher than the average statistical data of the whole China. The correlation coefficients between the total and bioavailable concentrations of REEs were from 0.66 to 0.95 （P〈0.001, n=63）. This suggests that it is necessary to study the bioavailable and total heavy metal concentrations in soils in order to assess the ecological and environmental effects, and to provide scientific information on REEs application as micro-elemental fertilizers, and consequently their potential health risks. The percentage of the bioavailable concentrations in the latesol derived from some kinds of parent materials was up to 50%, indicating that it was unnecessary to apply REE micro-elemental fertilizers in the soils.
