Urban Space Renewal in the Context of Urban Shrinkage:Taking Chongqing City as an Example
Under the intervention of any variable,the spreading effects cannot exceed the backwash effects,and the urban contraction cannot be avoided.If urban renewal is carried out blindly without regard to the phenomenon of urban shrinkage,it will not only lead to homogenization of cities but also waste resources.Firstly,the concept of urban shrinkage is clarified through urban contraction based on natural urban scale and four stages of population and economy and space under urban contraction.Then,based on CiteSpace,sorting out the similarities and differences of urban shrinkage and renewal,and conclude that large-scale renovation is no longer the mainstream.Urban space needs micro-renewal.Taking Chongqing as an example,analyze the current situation of Chongqing's shrinkage based on ArcGIS,and analyze the development direction of Chongqing's renewal under the background of shrinkage.
