Study On The Ecological Restoration And Landscape Reconstruction Design Of Waste Landfill Site

With the rapid development of China’s economy,the deepening of the process of urbanization,people’s living standards is being improved,urban scale has been amplified,while the number of urban solid waste and construction waste increases annually.It results that a lot of land resources are occupied and "junk Besieged City" is becoming more serious.At the same time due to the large amount of garbage piled up in a landfill,the degradation time is longer,and it will produce large quantities of pollutants in the degradation process.As a result it will damage the surrounding environment seriously and cause more and more surrounding area ecological environment problems In order to maintain the balance of the ecosystem.Restoring the destruction of ecosystems,re-use of waste,landfill transformation has become practical problems which need to be resolved.According to the research on related concepts of landfill,and the studies and analysis of domestic and foreign landfill landscape reconstruction-related case,the problem of our country’s landfill ecological restoration and landscape reconstruction can be analyzed.Though the restoration of our country’s landfill waste land started late,in recent years,the corresponding work also gradually starts,and the government,relevant agencies,businesses and the community also give the positive response.So we have achieved some results in all aspects of theoretical research,practical application,etc.But we need have a further study of research and practice because of the gap with developed countries.Ecological restoration and landscape reconstruction of landfill waste land is a comprehensive ecological restoration process,which is different from the general landscape construction,which is due to its special nature of the land of the decision.Wasteland ecological restoration procedure is a part of the reconstruction of the landscape,but also is the precondition of landscape reconstruction.At the beginning of wasteland ecological restoration,it is important to put the goal of rebuilding the landscape into the overall project objectives and combine ecological restoration engineering with landscape reconstruction process closely.Based on the research of landfill waste land of ecological restoration and the relevant theory and related cases of landscape reconstruction,this thesis analyzes the formation,characteristics and type of waste landfill.Meanwhile waste disposal,reshaping the landscape,soil improvement,vegetation restoration and pollution control and other issues in the process of ecological restoration are discussed.It includes the reconstruction of the landscape’s orientation,pattern and design principles and methods.Finally as a example of Beijing Nanhaizi park ecological restoration project,it verify the theory of ecological restoration and landscape reconstruction of landfill waste land.By way of example the study concluded:landfill waste land landscape reconstruction and environmental governance,closely related to ecological restoration and landscape reconstruction,the entire waste reconstruction needs to integrate landscape reconstruction and ecological restoration as the guide of final landscape reconstruction objectives and takes advantage of the special traits of landfill management project.
