Construction Of Greenway Network And Key District Planning Based On Suitability Evaluation In Historic Urban Areas

With the rapid development of the city,problems such as high building density,poor living environment,serious lack of public space,inadequate non-motorized system and so on are common in the old urban area,which is a major threat to the historic urban areas with many historical and cultural relics.Greenway network has the functions of protecting historic sites,connecting the non-motorized system,improving the quality of urban space,etc.Constructing greenway network in historic urban areas can effectively restrain and solve some problems caused by the development of urbanization.However,the construction of greenway network in historic urban areas is different from other urban areas,and its planning and design is more challenging and complex.Based on the above problems,this paper firstly studies the relevant theory of greenway network,historic urban areas,and relevant cases,and summarizes the characteristics,requirements,construction significance,spatial level and planning points of the greenway network in historic urban areas combined with the relevant data of the current domestic greenway network construction in historic urban area.Secondly,taking the method of Greenway suitability evaluation as the main research method,taking Wuhang historic urban area as an example,through the analysis of resource conditions,the establishment of Greenway suitability evaluation system,the preliminary greenway route selection,and the optimization and adjustment of greenway selection,the final greenway route selection is obtained.Then,from the perspective of empirical research,this paper constructs the greenway network of Wuhang historic urban area from the planning level,and puts forward the planning principles,planning structure,classification of Greenway types and various Greenway Construction Guidelines.From the design level,select the key district for greenway scheme design,put forward five strategies: shaping the linear space of the city,extending the space inside and outside the land,connecting the small corner space,connecting the rail transit distribution space,borrowing the natural landscape space,and specifically discuss the relevant special planning scheme.Through the combination of qualitative and quantitative methods,this paper takes Wuhang historic Urban Area as an example for empirical research,uses the suitability evaluation to explore the construction method of greenway network in historical urban areas,and puts forward the design ideas at the macro level and the micro level,to provide the technical route and support for the construction of greenway network in historic urban areas,and to promote the protection of historic urban areas from the perspective of landscape architecture.
