摘　　要：重金属单项控制技术在我国农田土壤修复中已有很多应用,但是面对复杂的土壤污染现状,缺乏基于不同风险等级的控制技术和治理体系,难以应对污染日益严重的不利局面,因此需要将各种单项修复技术进行合理的集成,形成污染耕地修复处理技术的筛选与集成方法体系。本研究基于适用于农田土壤修复的单项技术,包括植物修复技术、农艺修复技术、间套种技术、土壤淋洗技术和土壤钝化技术等,归纳和总结出不同类型技术的技术特性,形成土壤单项修复技术知识库,根据土壤污染风险等级、土壤理化性质、技术特性和人为因素等提出一种适宜的土壤修复技术筛选与集成的方法,为我国农田土壤修复/安全利用和可持续利用管理提供技术支撑。Soil remediation measures have been applied extensively in heavy metal polluted farmland in China. Because the control technology and remediation system are insufficient basing on different risk levels, it is difficult to deal with the soil pollution which has increasingly and seriously negative effects. Thus, it is necessary to integrate reasonably remediation technologies to find out a systematic methodwhich is effective for the remediation of heavy metal polluted farmland. This study is conducted to summarize and make conclusion thecharacteristics of various technologies which are suitable for polluted soil remediation, including phytoremediation, agronomic measure, interplanting, soil leaching and soil passivation, etc. On this basis, we are trying to propose an integration between methodology and technology considering risk levels of pollution, physical and chemical properties of soil, technical characteristics and human activities, etc. This research provides an effective approach to technical support for the remediation and sustainable utilization of heavy metals polluted farmlands in China.
