Analysis And Research Of Node Space In The Western Section Of Chaohu Avenue Based On Space Syntax

Urban node space is an indispensable leisure and recreation place for urban residents'life and plays an important role in the sustainable development of the city.Spatial syntax is a spatial analysis method based on spatial cognition.At present,most of the researches on urban node space in China are based on qualitative perspectives.There is little space as the main body for quantitative research,and the urban node space in China is in the background of rapid urbanization.There is a certain degree of irrationality in its planning and layout.The mathematical model of spatial syntax can serve as a relatively stable reference system and verification mechanism,providing technical support for analyzing urban node space,so that the spatial structure of urban nodes can be analyzed more objectively and accurately,making the layout structure more scientific and reasonable.Based on the space syntax theory,this paper sorts out and analyzes the urban node space and related theories.After clearing the research background,research purpose and significance,the joint space of the western segment of the Chaohu Avenue in Hefei City is taken as the research object,with the help of spatial syntax.As a technical support,the theory uses depthmap analysis software to establish an axis analysis model from the perspective of topology network,and select the integration value,connectivity,choice and intelligibility indicators for the 12 viewing platform node spaces in the western section of the Chaohu Avenue.Conduct quantitative analysis and propose a complete optimization strategy.The main research conclusions are as follows:(1)In the entire western section of the Chaohu Avenue,the global integrated nuclear appears in the Binhu new istrict of Hefei City,with Huayuan Avenue,Huizhou Avenue,Luzhou Avenue and Yungu Road as integrated nuclear main shafts and sub-integrated cores appeared in the Feixi County area.With the increase of the topological radius,the integration value of the western section of the Chaohu Avenue tends to be unified.The integration value of the Lujiang County area is the largest,and the integration value of the Hefei urban area has always been at a high level.(2)In the service area of Hefei urban area,the integration value of Yulan platform and Yingchun platform are at a high level,and the spatial accessibility is good;the connectivity of Yulan platform is relatively high,which forms a good visual penetration effect,and the opposite of Yingchun platform both of them are at a high level in terms of choice and intelligibility,forming a good overall effect in the overall situation.(3)Within die service area of Feidong County,the integration value of Guihua platform,Sidingshan and Fisherman's Wharf is higher,and the road convenience is better;the road connection between the north and the south of Fisherman's Wharf is higher,but it is east-west.There is lack of close connection between the roads;Guihua platform and Sidingshan are close to the selection center,attracting people and traffic,but the selection of Fisherman's Wharf is low,and the vitality of the space needs to be improved;die intelligibility of the three is higher,people It is easier to recognize the structure of the overall space through the local space.(4)In the service area of Lujiang County,the integration value of Ziwei platform and Yuanwei platform is low,the accessibility of space needs to be improved;there are roads with high connectivity around Yinghua platform and Yuanwei platform,but the layout of Ziwei platform and Haitang platform on the road network with low connectivity;there are high-selection roads around Ziwei platform and Yuanwei platform,and the usage rate is high.The opposite of Yinghua platform and Haitang platform affects the usage rate to some extent;the understanding of the four is understandable.The degree is higher and the recognizability of the space is higher.(5)Within the service area of Feixi County,Meihua platform and Zijing platform are close to the integration center in the service area,which has good development potential;the connection between Meihua platform and Zijing platform and the surrounding space is close,but the connection degree of the lotus table is low.Meihua platform and Hehua platform are close to the selection center,and the space is full of vitality;the intelligibility of the service area of Feixi County is less than 0.5,indicating that it is not easy to form a good space for the entire space system in the three node spaces in the service domain Cognition.
