Study On Spatial Characteristics Of Baoding Historic And Cultural Block Based On Spatial Syntax

Historic and cultural blocks are the Memoirs of the vicissitudes of the city,and are important references for us to learn from history and use the past for the present.In the past,the study of historic and cultural blocks mostly showed significance outside the blocks,but ignored the analysis of their internal structure.In recent years,the focus of work has also changed from protecting historic buildings in the blocks to protecting the style of streets and lanes;from unilaterally emphasizing the protection of the material level to the protection of both material and non-material aspects.Baoding Ancient City has a history of nearly 3000 years.It was identified as the second batch of national historical and cultural cities in 1986.Among them,the Governor's Office-West Street,Huaijun Public Office-Qinghe Road Department,Dongjie-Beijie Historic and Cultural District are the core protected areas of Baoding Historic and Cultural City and the most complete business card of Baoding City.In the management and application of historic and cultural blocks,although the outline of Baoding ancient city is still in existence,the space management of blocks is inappropriate,the culture is absent,the characteristics are vanished,the space of blocks is densely populated and the congestion is serious.In order to better protect the characteristics and features of historical and cultural blocks,we need to adopt more scientific research methods and management means to strengthen the protection of historical and cultural blocks.By using the spatial syntactic theory and the related research of spatial syntactic software,combining quantitative analysis and comparative research methods,this paper quantitatively describes the morphological characteristics of street space from the perspective of spatial morphological cognition.The paper is divided into three parts.The first part is the introduction and theory.It includes the research background,the summary of relevant research at home and abroad,the purpose and significance of the research,the research content,the research methods,the technical route,the research characteristics and innovation,and the related concepts.In the second chapter,the theoretical basis of spatial syntax is elaborated,and the spatial characteristics of Baoding historic and cultural blocks are commented based on the general situation of Baoding ancient city and field research.This part is described as a solid theoretical basis for the syntactic study of Baoding historic and cultural blocks in the following chapters.Secondly,it is the research process of practicing spatial syntax in this paper.The axis model and line segment model are drawn by using spatial syntax software and quantitative principles.Several morphological variables of spatial syntax are used to study the characteristics of urban spatial morphology and land use change.By analyzing and comparing the axes models of main roads in ancient urban areas in different periods,the inherent laws of spatial form evolution are obtained,and the relationship between them and historical and cultural blocks is explored.At the same time,it emphatically analyses the spatial structure characteristics of historical and cultural blocks from the meso-and micro-level.Through the analysis of the syntactic morphological variables such as spatial integration,selectivity,intelligence,human flow interface and street network density,it interprets the overall and local spatial morphological characteristics of historical and cultural blocks,and then combines with the distribution characteristics of urban functional land use layout,sums up the unfavorable spatial morphological knots.The problems of structure improvement and land layout adjustment are summarized,and the corresponding relationship between spatial structure and social behavior is summarized.Finally,it reviews the research process of spatial syntax and draws a conclusion.The paper summarizes the evolution law of the spatial form of historic and cultural blocks: at the macro-urban scale,the urban layout is strongly related to the topological structure of the street spatial network,that is,the space with structural advantages can easily become the urban center;at the middle-scale,the spatial structure of the ancient urban area has obvious single-centricity,and the evolution of its integration core expands with the expansion of the urban scale;At the inner scale of the viewing block,the historic and cultural blocks in Baoding are confused,poorly understood and open.The spatial structure of streets and lanes needs to be optimized,the spatial hierarchy needs to be sorted out,and the spatial vitality needs to be enhanced.At the same time,some suggestions are put forward to promote the vitality of historic and cultural blocks.It is necessary to adjust the land layout of historic and cultural blocks appropriately,to realize the repair of traffic network and to enhance the vitality of historic and cultural blocks.Through the analysis of the law of spatial organization,it is conducive to the continuation of the texture of Baoding city and the protection of the historic space of ancient urban areas,thus promoting the management and implementation of the protection of historic and cultural blocks.It is also an exploration and innovation of the methodology of actively shaping the features of urban areas and enriching the historic and cultural blocks.
