| 摘 要： | 通过盆栽试验和现场布点试验，研究了铜、砷在水稻－土壤体系中迁移的规律。结果表明，该体系对铜、砷污染具有相当大的缓解作用；土壤中水溶性可交换态铜、砷含量很低；铜、砷主要累积在水稻根部；土壤中铜、砷相互有拮抗作用，确定土壤铜、砷临界值应考虑多因素综合作用。

| Abstract: | The movement of Cu and As in rice -soil systemand its effects on ecological environment rice-soil ecosystem pos-sesses significant mitigation effect on Cu and As pollution. Theconcentrations of soluable and exchangable Cu and As in soil arevery low. Cu and As entering rice are mainly accumulated in riceroots. The antagonistic actions are existing between soil Cu andAs.The critical value of Cu As in soil should be determinedupon the comprehensive viewpoint of multiple factors. |
