A Study On Public Space Renewal Strategies Of Old Urban Streets In Xi’an Under The Concept Of Healthy City

Health is an inevitable requirement for all-round human development,a fundamental condition for national economic and social development,and an important symbol of national prosperity and wealth.The Party Central Committee has long attached importance to the development of people’s health,and in the 14 th Five-Year Plan formulated at the Fifth Plenary Session of the 19 th Party Central Committee in 2020,it was stressed that "people’s health should be given priority in the strategic development of the country",with a view to comprehensively improving people’s health and promoting This paper is based on the concept of a healthy city.Based on the concept of healthy city,this paper takes the public space of old streets and lanes in Xi’an as the research object,summarises the current situation of the public space of old streets and lanes in the city,and compares typical cases of public space of streets and lanes.Finally,the correlation between healthy city and old streets and alleys is explained,providing relevant suggestions for the renewal of urban street space.The first part of the thesis is the introductory section,which presents the problem.The main contents are the background,purpose and significance of the study,the current situation of domestic and international research,research methods and research contents,and the systematic elaboration of research directions,forming the basis of this paper.The second part is a study of health-oriented urban environments.The paper explains the concept of health-oriented urban environment and how to use the concept of healthy city to improve the spatial environmental quality of old urban streets and alleys against the background of health problems in old urban streets and alleys.The third part analyses the current situation and problems of existing urban streets and alleys through visits and research,and provides an in-depth and thorough analysis of the current traffic situation,the current environmental situation,the current interface situation,the physical external environment and the daily health activity behaviour of the residents in the street space in the study area,which provides a reference for the design of the later part.The fourth part uses a web crawler tool approach to obtain urban big data information.Using POI point data and Baidu map building outline data,web data is constructed to analyse the relationship between a healthy city and its population,to obtain public service facilities in streets and alleys that have an important impact on residents’ health,and to analyse the coverage of public service facilities and the nearest public facility service area using Arc GIS software.In the fifth part,based on the analysis of the above issues,the public space renewal strategy of old urban streets and alleys under the concept of health is proposed in conjunction with the principles of healthy design of urban public space in Xi’an,providing a theoretical reference for the future construction of a healthy city.Finally,the conclusions and shortcomings of this paper are presented so that it can provide reference value in the renewal of old street spaces under a healthy city perspective.Based on the Xi’an Urban Renewal Measures issued by the Xi’an Municipal Government in November 2021,this study explores the construction goals of urban renewal in Xi’an towards beauty,improves the environmental quality of healthy public spaces in Xi’an’s old streets and alleys,meets residents’ needs for healthy living,and provides theoretical reference and practical reference for the study of old urban street spaces in Xi’an.
