摘　　要：论述了水环境中砷的赋存形态和水生植物对砷的富集作用。水生植物富集砷的影响因素包括环境因素（水体p H、氧化还原电位、磷酸盐含量和铁含量等）、植物自身因素（植物种类、植株的不同部位等）和培养时间与季节等。未来水体砷污染植物修复的主要研究方向包括砷超富集水生植物的筛选、砷富集功能基因的识别与克隆、富集砷的植物的处置与利用以及水体中重金属污染与修复效果的评价等。In this paper, the arsenic chemical forms in water and arsenic accumulation in aquatic plants were discussed. The main factors affecting the bioaccumulation of arsenic in water included environmental factors （pH, oxidation-reduction potential, phosphate contents, iron contents）, plant factors （species and different parts of aquatic plants）, and culture time and seasons. It was suggested that dressing by screening arsenic hyper-accumulator species of aquatic plants, the identification and cloning of functional genes involved in arsenic accumulation, the disposition and resource utilization of arsenic accumulators, and the assessment of heavy metal pollution in water would be the important domains to be explored in the future.
