Study On Ecological Restoration And Landscape Design Of Domestic Waste Landfill

Landfill is the inevitable product of social progress and the development of the times.It carries the memory of urban construction and life.The remaining landfill wasteland can realize the landscape value after completing ecological restoration and landscape regeneration.In recent years,the landfill that used to be located in the outer suburbs has gradually entered the urban space.The repair and recycling of the landfill can not only supplement the lack of urban green space,but also play an important role in the restoration of its ecosystem for urban environmental protection.Through literature study,this thesis summarizes the ecological restoration and Landscape Utilization of landfill sites at home and abroad.Firstly,it demonstrates the relevant concepts and main characteristics of landfill,as well as the development process and research progress of landscape restoration of landfill waste land.This thesis selects representative examples of landfill reconstruction at home and abroad for theoretical research on restoration measures,and selects four cases of domestic Beijing Nanhaizi country park,Hangzhou Tianziling ecological park,Binzhou hehe Wetland Park and Qingdao Xiaojianxi landfill for on-site investigation and survey.Through the analysis of the base site,design concept and restoration status of the example,it is proposed to build a country park model with "natural wild interest" as the core to carry out ecological restoration and site reuse of Jibei domestic waste landfill.Combined with the landscape planning and design methods and theories of urban country parks,this thesis summarizes the ecological landscape planning and design methods of domestic waste landfill,and guides the planning and design of Jibei country parks.According to the foundation site of Jinan Jibei domestic waste landfill and its surroundings,the site is comprehensively analyzed in combination with natural features,geological environment and cultural resources.The landscape construction of domestic waste landfill wasteland in Jibei is positioned as a country park.The comprehensive planning forms the landscape spatial layout of "one ring,five areas and sixteen points",and the planning and design includes five functional zones: management service area,forest landscape area,ecological education demonstration area,wetland landscape area and leisure and fitness area.The management service area is dominated by the entrance platform landscape,and is designed with the main view of the entrance of "see the gate of the mountain","see the shape of the mountain" and ecological parking lot to meet the service functions of the entrance of the basic park;In the forest landscape area,there are mountain forest sightseeing landscapes such as jungle secret land,meditation garden,storm corridor and watchtower;The ecological education demonstration area consists of space-time square,solid waste "brick and stone",resource wooden house and other landscape spaces;The wetland landscape area is built around the ecological wetland,which is mainly for leisure viewing and has the function of ecological science popularization;The leisure and fitness area provides a place for leisure,fitness and communication for people of multiple ages.Taking environmental protection engineering as the pilot measure,the landfill shaping treatment is carried out on the basis of standardized site closure,and the pseudo natural mountain shape is constructed in the mode of low excavation and filling earthwork;The overall layout comprehensively considers the hard environment and vegetation community in the original site,and recycles the construction waste generated by demolition and construction in the site into hard materials for landscape reconstruction;The plant configuration is mainly based on the ecological stability of the local natural vegetation community,appropriately improve the vegetation richness,and build a stable ecological repair vegetation layer;Build a self circulating water ecosystem with the model of constructed compound wetland;Take ecology and naturalization as the main landscape performance,pay attention to the popular science,publicity and education of the concepts of ecological protection and waste recycling,and finally complete the planning and design scheme of Jibei country park,so as to explore the theoretical guidance of the integration of landscape architecture discipline in the process of landscape restoration and ecological function transformation of landfill site,and provide multiple perspectives for this type of land recycling.
