Research On Living Street Space Problem And Optimization Strategy Based On Healthy City Concept

With the rapid development of economic and urban construction,public health problems such as environmental pollution and high incidence of chronic diseases brought about by rapid urbanization have gradually emerged.The concept of “healthy city” has correspondingly received widespread attention.Under the guidance of the concept of “healthy city”,countries are actively exploring the relationship between health and urban space and social environment,and reflect on the shortcomings of the current urbanization model.As a built space environment with the closest relationship with urban residents,living street space has the most direct relationship with the health status of citizens.Therefore,this paper has carried out targeted discussions on the current situation and optimization strategies of living street space.Under the guidance of the concept of healthy city,this paper takes the living street space in the built environment as the research object,and analyzes the health status of the living street space from the subjective and objective aspects through field research and survey questionnaire,to find out the existing health problems.Combined with interpreting the domestic and international street space design guidelines and excellent cases,this article finally proposed the living street space design optimization strategy.The overall structure of the article is divided into the following four parts:The first part is basic research.On the basis of defining the concept of healthy city and living street space,this paper analyzes the development history of relevant theories and the classic cases at home and abroad.Finally,it expounds the relationship between the healthy city and living street space.The second part is the analysis of the influencing factors.Based on the summarization of theories and cases at home and abroad,the paper analyzes and summarizes the relevant factors of the living street space that affects public health from the three functional levels:public service,traffic travel and social interaction,which provides research basis for the current situation investigation.The third part is the status investigation and problem analysis.based on the current situation investigation and questionnaire analysis of Mianzhuang Street in Xicheng District,Beijing,the article sorted out the existing health problems in Beijing’s living street space,which provides a theoretical basis for the future optimization strategy.The fourth part is the optimization strategy.This part proposes the optimization strategy from the three aspects respectively: service facilities,slow-moving system and micro-space,in view of the current situation of the living street space in Beijing.
