中文摘要:

      通过对农田土壤重金属污染现状的阐述，分析当下农田土壤重金属污染来源，总结提炼农田重金属安全利用技术和发展趋势，最后提出农田土壤重金属修复，一方面要对污染源进行“溯源断源”，另一方面要因地制宜选取合适的技术。同时，应全方位考虑，利用不同技术的联合作用修复土壤重金属污染的思路，希望能为农田土壤重金属污染成因机制与安全利用提供理论与技术参考。

英文摘要:

      This paper systematically expounds the current situation of heavy metal pollution in farmland soil, analyzes the sources of heavy metal pollution in farmland soil, and summarizes the safe utilization technology and development trend of heavy metals in farmland. Finally, it is proposed that the remediation of heavy metal pollution in farmland soil should be traced and cut off from the source of pollution, and on the other hand, appropriate remediation technologies should be selected according to local conditions, and at the same time, the idea of using the combined action of different technologies to repair soil heavy metal pollution should be considered comprehensively. It is hoped that it can provide theoretical and technical reference for the causal mechanism and safe utilization of heavy metal pollution in farmland soil.
