摘要: 讨论了污染土壤生态修复的理论内涵、修复方法的优化组合及其应用案例。将污染土壤生态修复的目标拓展为:目标污染物降低到可接受程度、土壤生态毒理性降低到可接受程度、部分恢复或全部恢复土壤的生态服务功能。归纳出污染土壤生态修复的5个特点、5个原则。初步提出污染土壤生态修复方法优化组合的原则。污染土壤生态修复方法优化组合表现出以植物、微生物为中心,具有同步组合和阶段组合两种组合方式的特点。污染土壤生态修复的实际案例中,修复表现出以下流程:本底调查→改善基础环境→生物修复→效果评价。目前,虽然各方法或措施间的优化组合是污染土壤生态修复研究的重点,但对于优化组合方式中各要素间的作用机理等内容的研究还应进一步加强。此外,促进研究向实际应用的转化也是污染土壤生态修复必然要面临的问题。进一步充实、完善污染生态修复的理论内涵,建立起污染生态修复的理论框架,应是目前的首要任务。

Abstract: This paper discussed the theoretical connotation of ecological remediation of contaminated soil, related measures, their optimal combination, and case applications. The goals of ecological remediation of contaminated soil were expanded as: Decreasing target pollutants to acceptable level, decreasing soil eco-toxicological properties to acceptable level, and recovering part or all soil ecosystem services. Five characteristics and five principles of ecological remediation of contaminated soil were summed up, and the principles of optimal combination of related measures were proposed. At present, the optimal combinations of related measures have the characteristics of taking plant and microorganism as the core and of simultaneous and asynchronous. In the case applications, the process of ecological remediation of contaminated soil is: Background investigation → improving basic environment conditions → bioremediation → evaluation. Though the optimal combination of related measures is the key in ecological remediation of contaminated soil, its mechanisms should be further studied. In addition, to promote the conversion of laboratory study to actual application is an inevitable problem in the studies of ecological remediation of contaminated soil. It is the foremost to further enrich and improve the theoretical connotation of ecological remediation of contaminated soil and to establish related theoretical framework.
