Landscape Design Of Landscape Design Along Railway Line Under The Background Of Urban Double Repair

Railways have always been one of the indispensable modes of transportation in public transportation,and railways play a vital role in the economic development of cities.When passengers enter the city by train,the landscape along the railway represents the passenger's primary impression of the city.As an integral part of the ecological corridor in urban space,the landscape along the railway plays an indispensable role in the urban ecosystem.With the accelerating urbanization process,the problem of "urban disease" has become increasingly prominent.At the same time,in the process of railway construction and train operation,the ecological environment along the line has suffered different degrees of impact at different stages.The city's double repair work is in full swing across the country.How to apply the concept of urban double repair to the landscape design along the railway,and what methods are used to improve the ecological environment along the railway.Under the premise of ensuring the ecological benefits of greenbelt along the railway,rational development and utilization of greenbelt along the route and alleviation of the shortage of environmental infrastructure along the route are the main research priorities of this paper.Through field investigation and related literature research,this paper analyzes the impact of railway operation on urban ecological environment and the status quo of railway along the railway,and summarizes the dynamic mobility,hierarchical blending and strip continuity of the landscape along the railway.Six basic characteristics of visual transients,elemental diversity,and subject relativity.Four basic design strategies for landscape design along the railway in the context of urban double repair are proposed,including ecological priority,to restore the ecological environment along the line as the primary purpose;to protect the green space function along the line based on protection;and to design the sub-section for the landscape characteristics along the line;construct in stages.The three design principles including the principle of satisfying the functional requirements,restoring a good ecological environment,and creating an overall coordinated spatial form were determined.In the design content,research was carried out from the restoration of the ecological environment along the railway and the repair of the living environment.Through the analysis of the current situation and location of the actual project along the Beijing-Guangzhou Railway in the old section of the city,it is finally positioned as "a continuous eco-city green axis" and "a dynamic business card with the characteristics of the Qiaokou District ".It will "strive to create a natural ecological green axis,a continuous strip of green space that reflects the intertwined experience of modern urban landscapes and pastoral scenery,and a colorful space corridor that reflects regional characteristics."As a design goal.The principle of ecological priority,the principle of adapting to local conditions,and the principle of regionality are the basic design principles.On the basis of the overall spatial layout,according to the site function and landscape features,the whole will be divided into five sections:the old city style,the time town,the Bishui garden,the Suibin scenery area and the wetland garden.
