【 摘 要 】

Soil plays an important role to human health. Selenium is an essential nutrient for health. Se in soil will affect human health mainly by transferring to rice and other crops, and then to human body through the food chain .So it's necessary to analyse distribution of Se concentration in soil and its bioaccumulation ability from soil to rice. In this study, concentrations of soil Se ranged from 108.41-618.23μg/kg by counties. The average value was 343.90μg/kg, which was higher than soil background. It indicated that soil in Hainan was loaded with selenium. Soil in northeast contains more Se than that in southwest and Se content in natural soil was significant higher than cultivated soil. Positive correlations were seen between soil Se, rice Se and C/100,000. The transfer ability of Se varies in counties.
