Research On Spatial Structure And Morphological Characteristics Of Streets And Lanes In Guzhen Town Of Anshun

The layout of the “Bagua Array” in the ancient town of Anshun,Guizhou Province is a rare layout pattern in the traditional ancient towns of China.The old towns in the old state are expanded on the basis of historical protection areas,although the buildings and walls of the ancient ancestral temples in the ancient town have been compared.Serious damage,but the traditional space such as street trends,residential forms,overall layout,etc.are relatively well preserved,and the old towns in the old state ensure the integrity of the street structure in the development of the modernization process.Therefore,the shape and layout of the old towns in the old state have great specialities in the traditional Chinese historical settlements.The integrity page of the current street structure has great research value and reference significance.The research method adopted in this paper is based on morphology,using the theory and method of space syntax to quantitatively study its morphological structure,and analyze the spatial structure,shape and layout law of the streets and towns in the old towns of Old Zhou,and analyze the results of morphological and syntactic analysis.Combine to get relatively scientific conclusions.Based on the analysis of the geographical environment,historical background and human factors of the old towns in the old towns,this paper firstly gives a preliminary understanding of the spatial structure of the streets and lanes,and on this basis,the evolution of the spatial structure of the streets and lanes is qualitative.The general law is summarized,combined with the space syntax street space structure for further modification and subdivision,and the in-depth quantitative analysis and objective evaluation of street space type and building space type are carried out in a layered manner.From the technical method,the spatial accessibility efficiency is used as the division standard to divide the street into three levels,which is used as a clue to the structural characteristics,plane type,building function type and spatial configuration of the street space in each layer.Research and comparison,trying to explain the spatial characteristics of the streets and streets of old towns and the distribution characteristics of building types.The conclusion of this paper is that the shape of the old towns in the old state is mainly affected by the natural environment,policy background and ramps,forming a flat-type cluster-type cluster-type settlement structure;the old-fashioned towns have clear network structure and space.It is clear that during the evolution process,the "inward-gathering" type of spatial form is maintained on the basis of the streets and lanes of the historical area,forming the current "cross + two-ring" street space structure system,which has formed a reachability efficiency.Priority,the distribution of building function types is generally distributed according to the priority level of accessibility efficiency;the evolution of the street space structure reveals the composition of the old settlements of the old state,North Street,Xinnan Street and Xindong Street.The process of proliferation and development gradually formed the spatial structure characteristics of the inner and outer rings.
