摘　　要：综述了土壤中砷的形态、毒性、转化、污染等研究现状和土壤砷有效性的影响因素,以及砷对作物形态、生理、产量等的影响,总结了作物砷毒害的生理机制,分析了作物砷毒害研究中存在的问题,提出了今后的研究方向和建议.Forms, toxicity, transformation, current research situation of arsenic contamination in soil and its influencing factors were summed up. The paper also reviewed effects of arsenic toxicity on crop morphology, physiology, yield and mechanism of arsenic toxicity. Based upon analyses on the exiting problems in arsenic toxicity research,the research trends and proposals were put forward.
