Research On Ecological Restoration And Landscape Regeneration Of Landfills And Surrounding Land After Closure

With the rapid development of industrial civilization and urbanization,the prosperity of manufacturing industry and the abundance of living materials have led to the mass production of all kinds of garbage.However,due to lacking of environmental awareness and the backward waste disposal methods,garbage has brought great harm and influence to the ecological environment.As the most important waste disposal method,landfill brings huge pollution to soil,water and air due to improper measures and a large number of illegal and informal landfills,and then poses a serious threat to the ecological environment on which people and animals rely.On the other hand,the rapidly growing population density leads to a serious shortage of public green space,and garbage siege causes people to live closer and closer to the garbage dump.How to improve the surrounding environment of landfill to provide a harmonious and comfortable green space for human beings has become an important research topic concerned by professional scholars.By using case analysis,field research and other methods,this paper comprehensively analyzes the design cases at home and abroad,focuses on the restoration and regeneration of the landscape after the closure of the normal domestic waste landfill,and expounds the definitions and concepts of domestic waste landfill,urban waterfront landscape and country park.By analyzing and summarizing the cases of more than 50 landfills being transformed into green land at home and abroad,this paper discusses the principles and methods of landscape ecological restoration on landfills,in an attempt to provide reference for the landscape reconstruction of regular domestic garbage landfills after closure.Taking Lao Gang municipal solid waste landfill in Shanghai as an example,this complex industrial park and country park are planned and designed from the perspectives of topography shaping,vegetation restoration,drainage and water purification,and staging planning according to the site status and superior planning.Based on the analysis of the current situation and historical culture of the site,the paper puts forward the design concept,objectives and principles suitable for the site,and puts forward specific landscape design methods,which are mutually verified with the theoretical system proposed above,so as to provide reference for the landscape transformation of domestic garbage landfill in China in the future.
