Abstract Based on evaluation of surface soils in Quanzhou county of Guangxi and studied characteristics of selenium overall distribution, controlled factors and ecological effect of soils were presented. The results show that there has a large area of selenium-rich soils. The average selenium content is 0.60×10-6. Selenium-sufficient and selenium-rich soil’s area occupies 17.38% and 81.88% of the total area. The distribution of selenium in soils is affected by soil parent material, soil type, pH value and so on, which mainly controlled by soil parent material and has obviously inherited. The soil environment quality of the study area is good and the selenium-enriched agricultural products are rich, which has good development prospect.
