Study On Landscape Design Of Waste Landfill Based On Restoration Ecology

The output of municipal solid waste is increasing year by year,which leads to the increasing number of waste land in municipal solid waste landfill,These landfills not only degrade the surrounding ecology and bring serious pollution for several years,but also affect the image of cities and hinder the process of urbanization in China,It is an urgent problem to be solved on the road of sustainable development in China.In this paper,under the guidance of the concept of restoration ecology,the waste land of urban landfill is taken as the research object,and the landscape design of Sandao landfill in Changchun is studied,Under the guidance of the concept of restoration ecology,this paper takes the waste land of municipal solid waste landfill as the research object,and takes Sandao landfill in Changchun City as an example to study its landscape design,so that the polluted site can be reused,the utilization rate of the site can be increased,and the ecology can be restored,so as to provide reference and help for the landscape design of municipal solid waste landfill.The results are as follows:First,through a large number of literature reading,data search,as well as the overview of restoration ecology and the status quo of landfill wasteland research at home and abroad,it can be seen that restoration ecology has important guiding significance for ecological restoration and landscape design of landfill wasteland.Secondly,the representative typical cases are selected from the ecological restoration cases of municipal solid waste landfill and analyzed to find out the reference points,summarize and sort out the landscape design conclusions that can be used for urban solid waste landfill,so as to provide reference for the design cases.Thirdly,Taking the landscape of waste landfill as the research center,based on the concept of restoration ecology,this paper studies the landscape design of waste landfill,and puts forward the corresponding new landscape design strategies.For the landscape design of the waste land in the landfill,it should meet the purpose of ecological restoration at the same time,according to the need of landfill site restoration,as well as the restoration of ecological landscape level research objectives,from the perspective of landscape design,this paper puts forward the countermeasures and methods of landscape design of landfills in terms of topography,plants and water body,so as to improve the productivity and service function of waste landfill.In addition,sort out 100 kinds of landscape plants,which can not only resist soil heavy metal pollution,but also meet the design and ornamental needs,and it is applied to the design of the site.Fourthly,taking Sandao landfill in Changchun City as an example,Combined with the current situation and design needs of landfill site,the corresponding design concept and site specific design scheme are put forward,realizes the ecological restoration and landscape design based on restoration ecology on the waste land of the landfill,improves and restores the good ecological environment,on this basis,further restoration of site use value,build ecological areas,connect the surrounding resources,to provide sustainable and available resources and environmental basis for social and economic development,improve the regional ecosystem,To promote the sustainable development of regional ecosystem,and also provides better services for the surrounding people.
