摘　　要：土壤污染是影响粮食安全的重要因素,给人体健康和生态环境带来严重威胁。目前,我国土壤污染已从单一污染向复合污染转变,这对污染土壤修复技术提出更高的要求。结合农田土壤污染产生的原因,分析常见的土壤污染类型,如重金属污染、多环芳烃污染及微塑料污染,综述污染土壤修复技术的研究进展。总体来看,要合理利用金属氧化物纳米材料、生物炭等土壤改良剂,将高级氧化、微生物修复与植物修复等技术相结合,有效修复农田污染土壤,切实保障我国粮食安全。Soil pollution is an important factor affecting food security,posing a serious threat to human health and the ecological environment.At present,soil pollution in China has shifted from single pollution to compound pollution,which poses higher requirements for soil remediation technology.Based on the causes of soil pollution in farmland,the common types of soil pollution such as heavy metal pollution,polycyclic aromatic hydrocarbon pollution,and microplastic pollution are analyzed,and the research progress of soil remediation technology for polluted soil is summarized.Overall,it is necessary to make reasonable use of soil amendments such as metal oxide nanomaterials and biochar,and combine advanced oxidation,microbial remediation,and plant remediation technologies to effectively remediate polluted soil in farmland and ensure China’s food security.
