Research On The Double Repair Strategy Of Street Space In Fast-Growing City

Under the continuous advancement of the country's rapid urbanization process,a large number of cities have rapidly expanded the scale of cities and developed urban land incrementally in a short time,and a large number of fast-growing urban areas peculiar to the new era of urban development have emerged.Due to the short development and construction time,such urban areas generally lack scientific macro guidance and urban features,disordered land development and ecological environment.The resource allocation is unreasonable,and the facilities is imperfect.Urban problem is increasingly prominent,and the city increasingly sharp contradictions.In response to this phenomenon,in 2012,that state decide to transform the urban development gradually from incremental expansion to inventory optimization,and its development focus also shifted from extensive “quantity” to refined “quality”.In 2015,the concept of “double urban repair” was put forward as an important means to realize the transformation of urban development mode and governance mode at this stage.As the most important public space of a city,urban street space is the direct space that people contact and observe in daily life.It is also the basic framework of urban space structure and an important embodiment of urban image characteristics.In the development and construction of the fast-growing urban area,it has gradually become an important space for the outbreak of urban problems.How to use urban double repair as an effective means to solve the problems and contradictions unique to the street space in the fast-growing urban area has become the focus of this paper.In order to make the research results more practical and reliable,the st udy selected the Haxi area as a representative of the fast-growing city and became a research example of this paper.Firstly,through researching the literature,the research has systematically understood and mastered relevant research situations and practical cases at home and abroad,defined the relevant concepts of research,and divided the urban street space into three levels: macro,meso and micro.Secondly,the research selects the Haxi area as the object of the problem collection.After conducting in-depth literature understanding and field research on the Haxi area,it summarizes and analyzes the outstanding characteristics of the street space in such fast-growing urban areas,summarizes and analyzes the problems of street space at the macro,middle and micro levels.On this basis,it summed up the existing outstanding development contradictions in the street space.At the same time,combined with the concept of urban double repair,think about the planning of the street space in the fast-growing urban area,and then summarize the enlightenment.What the street space needs is a "efficiency","quality" of repairing,rather than a "delta" "reconstruction" pull down construction.Finally,aiming at the problems and contradictions in the street space of Haxi area,a comprehensive system double repair strategy is proposed from three levels: street network space,street linear space and street node space.This paper attempts to solve the problems existing in the street space of fast-growing urban areas,and proposes a more comprehensive and systematic urban double-repair strategy covering different levels,in order to find a new way for a large number of fast-growing urban street spaces that urgently need to solve problems.
