Landscape Ecological Restoration And Regeneration Design Of Discarded Landfill In Changchun City

Landfill wasteland regeneration has become an important issue in the process of global urban development.With the rapid development of urban economy and the continuous expansion of urban areas,the increasing population has led to an increasing number of household garbage,and the number and area of landfills have been growing.So far,China has accumulated more than 6 billion tons of garbage in the past few years,and the land of landfill and stacking has reached more than 3million mu.Nationwide,two-thirds of cities are under garbage siege.The increasing population has brought great pressure to the municipal solid waste landfills.The absorbing capacity and service life of the landfills have gradually decreased,and they are facing closure.It is an urgent problem to be solved in most cities in China how to regenerate a large number of abandoned land after the closure of the field.As one of the brownfield types,abandoned landfills themselves have a huge potential threat,which has an impact on the urban ecological environment and the living environment of residents.There have been many excellent practices in land reclamation of abandoned landfills at home and abroad,most of which are based on landscape regeneration design methods and technical means.This paper attempts to take Changchun municipal domestic garbage landfill waste reclamation as the research object,and carries out the research on landscape ecological restoration and recycling design of waste landfill waste.In this paper,the significance and purpose of the research are determined,the theoretical research and practical cases at home and abroad are summarized,the research content is established,and the comprehensive analysis and research is carried out on the study of abandoned landfills.Based on the definition of relevant concepts and site characteristics of domestic waste landfill,the paper compared and selected the recycling mode of domestic waste landfill,analyzed the related theories of landscape ecological restoration and landscape regeneration design of landfill,and summarized the construction of landscape regeneration design of waste waste waste abandoned land in Changchun.Workflow visit investigation about the present situation of changchun city garbage disposal,on-the-spot investigation changchun landfill already abandoned land,and carries on the analysis of changchun city landfill lands,living garbage landfill landscape regeneration is proposed,combined with domestic and foreign outstanding case design methods and technical means,summarizes the method is suitable for the design of changchun city landfill and ecological restoration technology.Finally,based on the case study of Mogugou Landfill,the design strategy of landfill wasteland regeneration is proposed,and its application is verified,and the conclusion is drawn.
