Quantitative Analysis of the Impact of Optimized Design of Urban Negative Space Living Environment on Community Vitality Based on Spatial Syntax Theory

Abstract

In order to obtain intuitive and quantitative analysis results, this paper chooses spatial syntax theory as the main basic theory of the study. Through field research in three typical negative spaces in linear cities around residential stations, we obtain the characteristics of pedestrian behavior and public needs, apply spatial syntax variables to quantitatively analyze the urban residential environment, explore the problems of urban public spaces and propose optimization strategies. Taking the spatial characteristics of the residential environment as the independent variable and the spatial vitality as the dependent variable, a model of the overall vitality influencing factors of the linear urban public space around the residential sites is established to obtain the degree of influence of each spatial carrier element on the vitality of the community. Analyze the optimized urban residential space based on spatial syntax as well as community vitality. The optimized urban residential environment has a high degree of integration and accessibility and a smooth road system. The spatial design is adjusted using spatial syntax to include the internal road network of open parks, in which the growth rates of the vitality parameter values of Longjiang Street, Hohsing Third Avenue Street, and Hengdao Street, for example, are 81.09%, 92.38%, and 73.40%, respectively, and the values of the vitality parameters of these streets are improved significantly.
