| The evolution of urban spatial form is the result of a combination of social,cultural and economic factors.Taking the Pingyao County as the research object,this paper summarizes the evolution of the modern Pingyao urban spatial form on the basis of summarizing the spatial characteristics of the ancient Pingyao traditional city,and it is composed of urban external form,urban spatial structure,urban road grid bureau and urban land.The modern evolution of traditional urban spatial characteristics analyzes and summarizes the evolution characteristics of modern Pingyao urban spatial form,and explores its influencing factors and comprehensive mechanism.Finally,it summarizes the current development problems of Pingyao and proposes corresponding suggestions.The paper mainly studies from four parts:First of all,the research on the spatial form of modern Pingyao city should first analyze and summarize the spatial characteristics of the ancient Pingyao traditional city.Through the background analysis of the construction of Pingyao City,the ancient Pingwei of the Northern Wei Dynasty was moved to the site as the boundary point,and the urban construction process was divided into two major stages,namely,the dynamic change stage and the stable development stage,and finally the urban construction was selected.In the perfect period,Pingyao in the Qing Dynasty summarized and refined the traditional urban spatial characteristics from five aspects: natural landscape pattern,urban spatial form,north-south axis sequence,human space structure and urban land use.Secondly: According to the analysis of social,economic and cultural backgrounds of Pingyao after liberation,the social and political background and the evolution of modern Pingyao urban spatial form are divided into five stages,and the main aspects of urban space construction at each stage.The performance was analyzed by qualitative and quantitative mining.Furthermore,the analysis concludes that since modern times,the urban space of Pingyao has gradually shifted from epitaxial expansion to connotational improvement.The external form of urban space has formed a cyclical change characteristic of compact and discrete,smooth and complex,and the relationship between the old and the new city and the city.And the formation of independent spatial structure,the old city center is declining,the new city center is constantly strengthening the institutional characteristics,the urban road network and land layout with the spatial expansion of the evolution characteristics and the traditional urban spatial characteristics of the inheritance and resolution.Finally,through the comparison of the five factors affecting the spatial pattern of urban development,economic impact,urban planning,regional transportation,and public participation in different stages of urban development,the specific impact of each factor is analyzed in depth,and the modern city of Pingyao is summarized.The comprehensive mechanism of the evolution of spatial morphology.Finally,the issue of modern Pingyao urban development was put forward and corresponding suggestions were made. |
