摘要:

农田土壤重金属污染直接影响农产品质量安全、威胁人体健康,因此,开展农田分类管理、实施土壤风险管控具有重要意义。本文在相关政策文件研读、国内外相关文献查阅的基础上,总结了中国农田土壤重金属污染现状及特点,分析了农田土壤重金属的来源,系统概括了农田重金属污染风险管控措施,重点综述了农艺调控类、土壤改良类和生物修复类等土壤修复技术的最新研究进展。最后,总结了目前农田土壤重金属污染风险管控中存在的问题并提出了展望。

Abstract:

The heavy metal pollution of farmland soil directly affects agricultural products’ quality safety and threatens human health, so it is of great significance to carry out the classification management and risk control of farmland soil. By reviewing relevant policy papers and literatures at home and abroad, this study summarized current situation and characteristics of heavy metal pollution in farmland soil of China, analyzed the source of heavy metals in farmland soil, and systematically outlined the risk control measures of heavy metal pollution in farmland. Moreover, this study highlighted the latest research progress of soil remediation technologies such as agronomic regulation, soil improvement, bioremediation and so on. Finally, existing problems in risk control of heavy metal pollution in farmland soil were pointed out and future research directions were discussed.

Key words: Farmland, Heavy Metal Pollution, Risk Control, Classification Management
