老垃圾填埋场采矿及其生态修复的研究进展

Research Progress in Landfill Mining and Its Ecological Restoration

老垃圾填埋场及其存量垃圾引发的资源浪费、环境污染及其对土地的侵占等问题,成为城市发展与生态建设的挑战,引起了日益密切的关注。从老垃圾填埋场存量垃圾的组成成分、理化特性以及老垃圾填埋场生态修复技术等方面,综述了国内外在该领域的研究进展,并对老垃圾填埋场采矿及其生态修复的社会、经济、环境分析方法、资源利用技术以及综合决策系统等潜在的相关研究方向进行了分析。

More and more attention has been drawn to urban old landfill sites and their stored municipal solid waste,which could bring recyclable resources' waste,environmental pollution and urban land occupation and became a serious challenge for cities' development. Current progress on the characteristics,physical and chemical properties and the ecological restoration technologies of urban old landfills and their stored municipal solid waste was summarized in this paper. Based on the reviewed literatures,researching directions in the area of landfill mining and its eco- remediation were put forward,including social- economic- environmental analyzing methods,resource utilization and eco- remediation technologies,and systemic decision support systems.
