Quantitative Analysis And Optimization Of Urban Living Street Space

With the improvement of people’s living standards,people have higher requirements for the quality of life.Living street space is an important part of urban public space and an important place for people’s daily life and communication.The contradiction between people’s increasing demand for quality of life and the existing problems of inadequate vitality and poor environmental quality in street space has become an urgent problem to be solved.This paper aims to establish a comprehensive quantitative analysis system,comprehensively analyze and evaluate the existing problems of living street space,and then put forward corresponding space optimization strategies.Firstly,this paper elaborates and defines the related concepts of living street space,combs the evolution process of street space at home and abroad and relevant theoretical results,summarizes the evolution law of street space at home and abroad and changes in human needs.It is found that the existing research lacks systematic definition of the elements of life street space,comprehensive quantitative analysis and evaluation of street space,thus lacking strong data support for the spatial optimization strategy.Therefore,this paper divides the elements of life street space from two dimensions,the external representation and space composition of street space.The exterior representation of street space is composed of people flow,behavior type and age structure elements.At the same time,the spatial composition of street space is analyzed in three-dimensional plane section,and it is concluded that the elements of street space are composed of plane shape,bottom interface,open space,section form,aspect ratio and side interface.The corresponding quantitative analysis methods and evaluation methods are put forward for each component,and the results of spatial component analysis are compared with those of external representation elements,so as to construct a comprehensive quantitative analysis and evaluation system for each component of street space.Secondly,the typical street space case in Guangzhou is investigated.Quantitative analysis method is used to analyze and evaluate the elements of street space.Combined with on-site observation and visits,the advantages and disadvantages of street space are comprehensively evaluated.Finally,the principle of street space optimization is put forward.On the basis of this,the specific optimization strategies of the street space on the plane,the section and the fa?ade are proposed to create a living street space full of "human feelings","life flavor" and "cultural flavor".This paper establishes a comprehensive quantitative analysis system,transforming the abstract street space environment into spatial data that is easy to understand and easy to operate,so that people can more intuitively evaluate the advantages and disadvantages of the living street space,so that people can better proposes an optimization strategy on Street space...
