摘要:

从改善人居的角度出发，填埋场修复与景观修复本 应是一体协作的。然而在项目实践中，在场地缺乏景观规划的 情况下，修复工程与景观工程往往脱节。基于此，从修复技术 对景观方案设计的掣肘处着手，分析了非正规填埋场原位修复 技术对场地条件的影响，以及以景观修复为导向的技术改进措 施和植物选择方案。在稳定化阶段，尝试建立模型细化方案， 采用撬装化设备，减少遗留设施的数量；在景观修复阶段，通 过与封场复绿、屋顶花园的植物选择方法比较后，归纳了适用 于非正规填埋场的植物选择条件。结合淮南2个非正规填埋场 稳定化项目案例，阐述了稳定化与景观修复的工作方法，以期 为类似项目提供借鉴。

Abstract:

From the perspective of improving human habitation, landfill restoration and landscape restoration should be integrated. However, in the practice of the project, restoration and landscape engineering are often disjoined in the absence of landscape planning. Based on this situation, starting from the constraints of remediation technology on landscape design, this paper analyzes the influence of in-situ remediation technology on the site conditions of informal landfills, and expounds the technical improvement measures and vegetation selection schemes oriented by landscape remediation. In the stabilization stage, it tries to establish a detailed model scheme, develop skid-mounted equipment, and reduce the number of legacy facilities. In the stage of landscape restoration, the selection conditions of plants suitable for informal landfills are summarized after comparing with the methods of vegetation selection for closed and greening and roof gardens. Based on two cases of stabilization of informal landfills in Huainan, this paper expounds the working methods of stabilization and landscape restoration, in order to provide some reference for similar projects.
