摘　　要：土壤砷污染所造成的环境问题逐渐受到人们的广泛关注。土壤植物修复技术主要是指利用植物来转移消除土壤中的污染物,具有绿色友好地解决土壤污染问题的优势。文章总结了土壤砷污染的主要来源和空间分布特点,简要地分析了砷在土壤中形态变化及其生物有效性的主要影响因素,探讨了现有砷污染土壤植物修复技术的发展现状,总结了砷高、低累积植物间套作修复“边生产边修复”的模式技术与机理,最后,文章对植物修复污染土壤的技术研究与实施机制进行了展望。The environmental problems caused by arsenic pollution in China have gradually attracted widespread attention.Phytoremediation technology mainly refers to the use of plants to transfer and eliminate pollutants in the soil,which has the advantage of solving soil pollution problems in a green and friendly way.In this paper,the main sources and spatial distribution characteristics of soil arsenic pollution in China are reviewed,the chemical speciation changes and bioavailability of arsenic in soil are briefly analyzed,the development status of existing arsenic-contaminated soil phytoremediation technologies is discussed,and the model and mechanism of intercropping remediation for"both crop production and soil remediation with high and low arsenic accumulation of heavy metals plant"were summarized.Finally,the prospect of the study on the phytoremediation of As contaminated soil was put forward,so as to provide the reference for the positive regulation of soil health and environmental safety.
