摘　　要：目前硒形态迁移规律成为研究者关注的焦点,特别是土壤-植物环节硒的形态迁移规律,硒形态迁移过程复杂,影响因素较多,导致对整个迁移研究过程中不能全面系统的分析认识,主要原因体现在土壤内外环境(pH、有机物、无机物等)以及植物自身结构特征等原因之间的交互作用。从土壤性质在硒迁移中的作用以及硒在植物中形态迁移变化归纳总结硒的迁移规律,分析硒在循环过程中形态、转化及其影响因素,并进行了展望。The transfer regularity of Se forms in the soil-plant link is the research focus.There are many influence factors during the transfer process of Se forms because of soil internal and external environment(pH,organic matter and non-organic matter),self structural characteristics of plants and interaction between soil and plants,which leads to insufficient overall and systematical analysis in research process of Se transfer.The forms,transformation and influence factors of Se transfer are analyzed by summarizing the Se transfer regularity based on the effect of soil property in Se transfer and change of Se forms transfer in plants and the research prospect on Se transfer in the soil-plant link is forecast at the same time.
