Research On The Public Space Design Of Xi'an Aging-friendly City Under The Health Orientation

With the increasingly severe trend of population aging,China,as a developing country,has undoubtedly increased the difficulty of solving the problem of aging before it gets rich.At present,it is difficult to meet the actual needs by relying solely on social and institutional support for the aged.It is more important to advocate the elderly to establish a positive life style,do a good job in self-health care and take the initiative to prevent diseases.Because of its good ecological environment and abundant activity facilities,urban public space has become an important occasion for the elderly to engage in social exchanges and leisure activities.Therefore,it is of urgent practical significance to provide healthy urban activity space suitable for the elderly to participate in.This paper,guided by health theory,reflects on the neglect of elderly people's life experience and health needs in urban public space design,aiming at establishing a design method of urban public space to meet the needs of the elderly,aiming at improving the elderly's life experience in the city and advocating healthy urban life.Firstly,it deeply analyses the demand,content,type and behavior characteristics of the elderly in urban public space;secondly,on the basis of the above-mentioned theoretical research,it discusses the travel safety principle,accessibility principle,communication promotion principle,comfortable experience principle and ecological aesthetic principle of health-oriented urban public space design for the aged.Six principles are put forward: rationalization of service radius,improvement of Road convenience and optimization of land use pattern from macro-planning level,and design strategies of building barrier-free system,improving spatial activity,mixing and diversifying functional layout,improving environmental comfort and diversifying service objects from meso-site dimension,as well as from the perspective of micro-facilities.The design strategies of optimizing pedestrian facilities,recreational facilities and activity facilities,and increasing intelligent science and technology facilities for the aged are put forward.Finally,through the in-depth investigation and study of the typical urban public space in Xi'an,combined with the health-oriented design principles and strategies for the aged urban public space proposed in this paper,the modular design idea is adopted to optimize the design of the urban public space from the aspects of macro-planning,meso-functions and micro-facilities,which provides a new idea for the outdoor space design of the elderly.The construction of urban public space for the aged has played a certain role in reference.
