Study On Revetment Landscape Planning And Design Of Qingyijiang Tunnel In Hongya County

Since ancient times,rivers have been an important resource for human survival.Cities are places where people gather,and rivers are the origin of urban development.Therefore,many cities have been built along the river,such as the Thames in London,the Nile in Egypt,China Yangtze and Yellow Rivers and the Tsing Yi River described in this thesis.With the rapid development of cities,the disorderly development and construction of human beings have caused extreme damage to ecosystems,and some have caused irreversible damage.River ecosystems are an important part of this.The ecological restoration of rivers has gradually attracted attention from all walks of life.In order for river ecosystems to start normal and orderly operation and restore the original ecology,more cities have begun to invest in the process of river ecological management.It is an important place in contact with the river,so it is also an important part of governance.In this paper,the sinking zone and the bank of Suihong Expressway in Hongya County,Meishan City,Sichuan Province are selected as research objects.Aiming at the status quo of the study area,this paper proposes the main technical concept of ecological restoration,with the purpose of restoring the ecosystem functions of the Qingyi River as the surrounding area Residents and tourists provide places for recreational activities to improve the overall image of Hongya County.At the same time,they also hope to provide a certain reference for the construction of similar types of urban riverside sink zone landscapes.In the research process,multi-disciplinary literature summary and analysis methods,field survey methods,GIS site analysis methods,and big data analysis methods were mainly used.The following conclusions were reached through related research:(1)Through the search and research of related literatures,the current situation of waterfront landscapes in cities at home and abroad is summarized,and the ecological improvement and landscape creation of the urban river sections in China and abroad are analyzed and summarized.The significance of governance and leisure viewing of citizens.(2)This article selects two cases of riverside park in Trencin,Slovakia,andcentral park landscape design of Wuhu business and cultural center for analysis,and learns the details of its ecological design methods,ecological restoration concepts,and human considerations.The advantages in the case will be provided to provide sufficient support for the ecological restoration design of the Qingyi River.(3)This paper uses the big data flow analysis method and the calculation of the design flood level to accurately locate the base.According to the seasonal water level,three levels of elevation are designed,which are 460 M,463M,and 465 M,respectively,below the contour line of 460 M.Submersible landscape trails,leisure trails at the 463 M contour line,and riding and walking pavements at the 465 M contour line are set up to cope with changes in water levels in different periods and form a three-dimensional landscape spatial level.(4)As the leading idea of the ecological decline zone,on the basis of fully respecting the original terrain,the landscape creation of the decline zone and the riverside road is based on cultural design,ecological design,seasonal design,and humanized design.For design principles,we have created special scenic spots such as "ecological wetlands","migratory birdhouses",and "aerobic drop in water",which can restore the function of ecological restoration of water bodies and enhance the space interaction between people and waterfront.(5)On the basis of the overall planning and layout,the thesis forms a spatial layout of "two zones,five zones,and multiple points." The "two zones" refers to: a major landscape axis that runs from the interior of the city to the urban decline zone.One is the leisure axis of the riverside landscape;the "five areas" include: ecological wetland leisure area,migratory bird woodland viewing area,cultural and historical sightseeing area,water-fall aerobic ecological area,and civic activity leisure area;"multi-point" includes historical and cultural display walls,Falls,waterfalls,and migratory birds viewing platform and other important landscape nodes.These elements have completed the landscape construction of Hongya County in an ecological way.
