Study On Ecological Restoration Strategy Of Landfill Based On Urban Landscape Optimization ——A Case Study Of Maiyuan Municipal Solid Waste Landfill In Nanchang

Since entering the 20th century,China’s urbanization process has been accelerating,and by the end of 2020,it has exceeded 63%.At the same time,urban land resources have become scarce resources.How to solve the problem of urban land pollution is becoming more and more important in landscape and other related academic research fields.As a part of the urban built-up area,the original suburban area of the city has gradually become a part of the urban built-up area.As one of the land spaces that need to be improved in the city,the accumulated garbage will have various negative effects on the city itself.From the perspective of ecological landscape,dealing with it based on ecological restoration technology and methods,and renovating and reconstructing urban landfill according to landscape ecological restoration strategy can solve the problem of shortage of urban land resources.In the same period,Nanchang is promoting the construction process of "Park City".The implementation of the design is of great significance to improve the urban living environment,establish new ecological nodes for the city’s current process of promoting Park City,and reflect the value of Park City.Through the integration of literature and periodicals,relevant case analysis at home and abroad,on-site investigation and other methods,this paper summarizes the relevant technical methods and experience summary of current urban landfill treatment,explores the relevant theories of economy,ecology and sociology,and starts from the three waste types of solid,liquid and gas and subsequent transformation through research review and case summary,The objective is to build a heap treatment suitable for future landscape construction,restore surface vegetation with suitable land and trees,create an ecological water landscape through leachate treatment,and improve the ecological environment of the site through gas conduction treatment.Combined with the change of land properties of the site in the future,relevant strategies for ecological restoration design of urban landfill are constructed.It has laid a good theoretical foundation and practical model for the follow-up case demonstration.Taking maiyuan municipal landfill in Nanchang as an example,the general situation of the case site is deeply understood according to the urban positioning,site conditions and policy interpretation,the overall design idea is put forward based on the analysis of the current situation of the case site,the integrated ecological restoration design strategy is constructed according to the strategy,and the demonstration is carried out from the aspects of solid-liquid gas treatment,ecological restoration and phased transformation,According to the current situation of the site,this paper puts forward the ideas,methods and strategies to adapt to the future development of the site,summarizes the advantages of the past strategies,and demonstrates the proposed theoretical system in practice,which has a certain reference and reference significance for the ecological restoration design of domestic urban landfill in the future.Figure[14]table[4]reference[55]...
