摘　　要：　针对土壤砷污染严重的环境问题,通过分析砷的环境分布及砷化合物的主要环境性质,探讨了砷的土壤环境容量、土壤中的行为及砷对作物生态效应等问题,进一步研究了土壤砷的来源和存在形态、土壤中砷污染对农作物生长发育的影响及在作物体内的累积规律,提出了严禁随意排放、控制含砷农药使用量以及施加石灰固定土壤中砷的防治措施。Aim at the seriously arsenic pollution in the soil,the paper discuses the environmental capacity of the arsenic, the environmental behavior of the arsenic and the effect on the crop. On the basis of analyzing arsenic's distribution and the main arsenide characters in soil. The source of arsenic and existing conformation are studied . At the same time,the infuences of arsenic pollution on crop growth and its accumulation law in the crop are investigated.The research bring forward three prevention and curing measures such as strictly prohibiting optional drainage, controlling arsenic pesticide usage quantity and fixing arsenic in the soil with lime.
