摘要
随着工业的发展与废弃物排放的不断增加,土壤的重金属污染问题日益严重并且引起了广泛的关注,广大学者开展了大量研究并取得了丰硕的成果。简要介绍中国土壤重金属污染的现状,系统分析农业用地土壤重金属污染元素、污染现状以及污染趋势,城市土壤重金属污染的现状与特征,着重探讨了农业用地土壤与城市土壤重金属分布的空间分异、迁移特征和迁移规律的影响因素,在此基础上提出目前土壤重金属污染研究中存在的问题与展望。
With the development of industrial and the increasing discharge of castoff, the heavy metal pollution of soil became more and more serious and had attracted wide attention. A large number of studies were carried out and achieved fruitful results. Here introduced the present situation of heavy-metal pollution of soil in China and systemically analyzed the heavy-metal element of soil pollution on agricultural land, and the status quo and trend of them. It presented the situation and characteristics of heavy-metal pollution in urban soil too. Meanwhile, it focused on spatial differentiation, transport characteristics and influencing factors for transport discipline of heavy metals in soil, and puts forward the questions and prospects in present study.
