Research On The Morphological Characteristics And Evolutionary Mechanism Of Chongqing City

The cities in the Chinese historical period have different forms and distinct characteristics due to the differences in the external conditions and internal conditions of the region's natural and social cultures.With the continuous advancement of industrialization and globalization,cities,both in terms of scale and quantity,far exceed the historical accumulation of thousands of years,but there are also thousands of cities.The problem of declining features reflects the current rapid development of urban construction.Lack of self-confidence and intrinsic vitality.The excellent traditional urban form is an important source of cultural self-confidence.We should not only imitate its external forms,but also inherit the outstanding things of traditional cities and buildings.Therefore,it is the premise of protecting and developing the regional characteristics of the city that the full understanding of the characteristics of the city's historical and geographical features and the formation and inheritance of the evolutionary laws.As a new perspective of urban historical preservation,the Urban Historical Landscape(HUL)expands and renews the scope of overall conservation,emphasizing the value diversity and dynamic evolution of urban heritage,and emphasizing the integration of historical cultural heritage protection and sustainable development.In this context,this article takes Chongqing as an example,focusing on the macroscopic and meso-level aspects of urban form factors,using field surveys,literature research methods,and various morphological analysis methods,combining qualitative and quantitative methods to identify cities from multiple perspectives.The characteristics of morphological elements and structures;in-depth analysis of urban spatial morphological characteristics is influenced by factors such as the natural environment,social,economic,and political factors.It focuses on the relatively constant morphological feature characteristics in the evolution process and analyzes the mechanisms of its inheritance and evolution.In the above,the protection,inheritance and development of urban historical landscape form are discussed from two aspects of “shape” and “god”.In view of the macro-level urban contours and landscape patterns,the paper sorted out the geometric characteristics and evolution of the urban contours of Chongqing from the pre-Qin period to the present and quantitatively analyzed the characteristics of the urban expansive intensity index,urban compactness,shape index and fractal dimension and evolution.In view of the meso-level urban land structure,the paper combs the spatial distribution characteristics and evolution of urban land from the pre-Qin period to the present.For urban street networks,the paper combs the geometric features of the street network in the historical district from the late Qing Dynasty to the present day;relying on the GIS platform,adopts space syntax.The software quantifies the urban street system in Chongqing to reveal its structural characteristics and evolution.On this basis,the thesis summarizes the rules of inheritance and evolution of urban outlines,land use structures,and street morphological features,and analyzes the mechanism of the inheritance and evolution of spatial morphological features.For the protection of urban history,it proposes to protect the unique natural ecological resources,historical urban patterns,and historical and cultural relics on the basis of a scientific understanding of the historical features of urban morphology.In response to the cultural heritage,it proposes to integrate traditional culture with contemporary culture,integrate it into related industries,develop together,and achieve the living heritage of traditional culture.
