Research On Optimal Design Of Public Space In Old Communities From The Perspective Of Healthy City

Healthy cities have become a development issue in the contemporary world.Under the trend of incremental slowdown and inventory optimization in Chinese construction,a large number of old communities have become shackles of urban renewal.The change of people’s lifestyle intensifies and exposes the weaknesses of old communities.The public space used by residents is occupied or missing to varying degrees,which is similar to the obsolete infrastructure,the disabled activity space,the mixed users,etc.,and these defects in the human settlement environment hinder the physical and mental health needs of the residents of old communities and the vision of a better life.Because the old community has long been built,nowadays our country is not advocating big demolition,big construction,the disorder of environmental functions also proved the necessity of healthy development of community,optimize and improve the public space,undoubtedly can have a positive effect on the residents’ material life,physical and mental health and so on.Therefore,this paper is expected to provide optimal design strategies for public space in old communities from the perspective of healthy city,in order to provide certain references for subsequent research in the same direction.This paper takes the public space of old communities in urban areas as the research object.In the context of healthy cities,first of all,it clarifies relevant theoretical concepts,and clarifies the needs of residents of old communities for health activities in public space by combing domestic and foreign studies on healthy cities and healthy communities,and interprets relevant domestic and foreign existing evaluation systems and evaluation standards in detail.The health components and design trends of public space in old communities are summarized to pave the way for the later research.Secondly,the old city of Xi ’an was selected as the scope of study,and a field survey was conducted by typical old communities to analyze the current situation of public space of old communities in the city,qualitatively sort out existing problems in public space,and conduct graphical analysis and study by applying software such as Ecotect and Depth Map.Thus,it summarizes the lack of health of public space in the community,and provides some reference for the following optimization design strategy.Finally,based on the healthy city development,the principles and objectives are established,and the rules for optimizing the design of public space in the old community are put forward.The paper expounds the materialization aspects of the community public space,including the healthy space and the healthy environment,as well as the spiritual and social aspects,and summarizes the specific optimization strategies of public space in the old community.In addition,different types of typical old communities in Xi ’an are selected as objects to optimize the design practice from the above four aspects.This paper hopes to make some expansion on the optimization of public space health of the old communities in Chinese cities,and make some help for the optimization practice of the old communities in Xi ’an,to provide reference for the healthy development of the city,and also to provide reference for the optimization of the same type of communities in the city.
