随着工农业的迅速发展，农田土壤Cd污染形势严峻。农田Cd污染将直接或间接地对土壤生态安全、农作物生长以及人类健康发展造成不良影响。Cd由于生物毒性强、易迁移蓄积而受到广泛关注，农田Cd污染亟需有效治理与控制。目前，农田土壤Cd污染修复技术逐渐发展和丰富，但针对修复技术的总结性分析相对欠缺。从农田土壤Cd污染的特点与危害出发，分析了农田Cd污染现状及其来源，在此基础上总结了农田土壤Cd污染修复技术的原理、特点及适用范围等，通过案例分析对比了修复技术的实际应用效果，并分析了各种修复技术的优缺点和应用局限性，以期为农田土壤Cd污染的防治与修复、农业高质量发展等提供一定的理论参考和借鉴。

With the rapid development of industry and agriculture, the situation of Cd pollution in farmland soil is severe. Cd pollution in farmland will directly or indirectly have adverse effects on soil ecological security, crop growth and human health development. Cd has received extensive attention due to its strong biological toxicity and easy migration and accumulation, and effective management and control of Cd pollution in farmland is urgently needed. At present, the remediation technology of Cd pollution in farmland soil has been gradually developed and enriched, but the summary analysis of the remediation technology is relatively lacking. The characteristics and hazards of farmland soil Cd contamination were analyzed, focusing on the current status and sources of farmland Cd pollution. Based on this analysis, the principles, characteristics, and applicable scopes of remediation technologies for Cd-contaminated farmland soil were summarized. Case studies were used to compare the practical application effects of these remediation technologies. Additionally, the advantages, disadvantages, and limitations of various remediation approaches were examined, providing theoretical references for the prevention and remediation of farmland soil Cd pollution and promoting high-quality development of agriculture.
