| 中文摘要: |
| 调研了某典型经济快速发展区修复后土壤处置现状，发现该区域修复后土壤处置外部化趋势明显，外部处置方式以水泥窑和“修复工厂”为主。梳理了我国当前污染地块修复后土壤再利用管理要求和再利用途径，在土方回填、绿化种植、建材化利用等再利用途径中，水泥窑建材化的应用较为普遍。分析了各地方或团体提出的修复后土壤再利用技术要求和工作环节，主要包括再利用区环境调查、风险筛选与风险评估、风险管控和长期监测等，在此基础上，提出建立全流程监管体系、重点推动修复后土壤土方回填再利用、鼓励经济快速发展区积极探索新模式等建议。 |

| Based on the investigation of soil remediation and disposal status in a typical region with rapid economic development， this study discovered a significant trend of external disposal after soil remediation in this area， with cement kilns and “remediation factories” being the main disposal methods. It sorted out the current management requirements and reuse approaches for soil remediation and reuse in contaminated sites in China. Being transformed into building material through cement kiln was relatively common among the reuse approaches of earthwork backfilling， green planting and building material utilization. It analyzed the technical requirements and processes for soil reuse after remediated proposed by various local organizations， mainly including environmental investigation in the reuse area， risk screening and risk assessment， risk control and long term monitoring， etc. In this regard， it proposed to establish a full process supervision system， focus on promoting the reuse of earth backfilling after soil remediation， and encourage rapid economic development regions to actively explore new methods. |
