| 摘 要： | 随着城市化快速发展与产业结构的调整，“退二进三”政策的实施以及重污染企业地理位置的变迁，使得多数城市产生大量可再利用再开发的场地。当前场地土壤环境污染状况日益严峻，对场地土壤开展污染物来源识别，成因解析和防控管理等已成为场地土壤污染治理修复的研究重点。基于国内外文献，综述了场地土壤污染物迁移转化过程、风险评估、治理修复等研究进展，发现场地中污染物的来源、输送的“源－汇”关系和不同介质/界面间迁移转化机制等环境行为的综合性研究有待进一步深化；风险评估框架与方法仍具有一定的不全面性和不确定性；绿色可持续联合修复技术已成为土壤修复治理的核心。未来需加强场地土壤“多来源、多途径、多介质、多界面、多尺度”环境过程和机理以及“排放来源、输送途径、迁移转化、动态累积”生态风险评估的系统研究，发展绿色可持续修复功能材料和技术，以期为我国本土场地土壤污染防控管理与修复治理提供依据。

| Abstract: | With the rapid development of urbanization and the adjustment of industrial structure, the environmental pollution situation of site soil is becoming increasingly serious. The source identification, reason analysis and prevention management of the pollutants in the site soil have become the focus of the research on the remediation of the soil pollution. Based on the literature at home and abroad, this paper summarized the research status and progress on the migration and transformation mechanism, risk assessment, treatment and remediation of the site soil pollutants. It was found that the comprehensive research on environmental behavior, such as the source of pollutants, the “source-sink” relationship of transport and the migration, the transformation mechanism between different media / interfaces, needs to be further deepened. The framework and methods of risk assessment were still incomplete and uncertain, the green and sustainable joint remediation techniques had become the core of soil remediation. It is necessary to strengthen the systematic research on the environmental process and mechanism of “multi-source, multi-way, multi-medium, multi-interface and multi-scale”, the ecological risk assessment of “emission source, transport route, migration and transformation and dynamic accumulation”, and to develop green and sustainable functional restoration materials and technologies in the future, which will provide theoretical and scientific bases for the prevention, control management and remediation for soil site pollution in China. |
