摘要
“十四五”时期我国土壤生态环境保护形势依然严峻,面对污染场地数量多、资金压力大、技术力量薄弱和城市发展用地需求不断扩大等诸多挑战,迫切需要揭示污染场地风险管控与区域可持续发展的交互作用机制,建立污染场地风险管控区划技术体系与分类管理决策支持系统。文章在充分调研国内外已有研究的基础上,从基于健康风险评价的特定污染场地分区管控、基于风险分级的区域污染场地分类管理和基于污染场地再利用的风险管控区划规划决策等3个方面分别阐述了污染场地可持续风险管控区划研究的基本思路,为统筹构建国家层面的区划技术体系提出了完善区划指标体系、兼顾利益相关方诉求和整合有效信息等可优化方向。通过研究进展整理与未来研究展望,以期为我国污染场地风险管控和再利用的分级、分类、分区管理提供精准决策支持,最终推动城市社会经济的可持续有序发展。
During the 14th Five-Year Plan in China,the situation of soil ecological environment protection is still serious with numerous challenges,for instance,the huge number of contaminated sites,the great financial pressure,the lack of qualified technical personnel and the continuous expansion of urban land.Aiming at establishing the regionalization technical system and classification decision-making support system for risk management of contaminated sites(RMCS),it is urgent to reveal the interaction mechanism between RMCS and regional sustainable development.The paper firstly conducted a systematic analysis of international literatures.Then,the principle idea of sustainable RMCS was elaborated in terms of three aspects,including specific regionalization of RMCS based on health risk assessment,regional classification management of contaminated sites based on risk ranking,and regionalization/planning decision-making based on the redevelopment of contaminated sites.Finally,the optimization direction for the comprehensive establishment of the national regionalization technical system was proposed from three perspectives improving the regionalization index system,involving stakeholders’considerations and integrating effective information.Supported by the systematic analysis of research progress and prospects,the findings are expected to provide precise decision-making guidance for ranking,classification,regionalization and redevelopment planning of contaminated sites,and lead to the sustainable development of the urban social economy.
