Research On The Space Suitability Of Historical Streets And Alleys In Changsha

At present,the aging trend of our society is accelerating.Compared with the ordinary old city streets,the aging degree of historical streets is often higher;At the same time,the old city reconstruction activities often lack of attention to the elderly and other special groups,which makes the contradiction between the historical streets and the elderly more acute.Based on the above phenomenon,This paper takes the historical streets and alleys of Changsha as the research object,starting from the activity characteristics and needs of the elderly,constructs a set of quantitative analysis model with the help of AHP,and quantifies the spatial environment of historical streets and alleys into specific data.At the same time,combining the three types of typical historic streets in Changsha,a more intuitive and multi-dimensional quantitative analysis of the current status of the ageability of the historic streets and alleys,and then proposes an optimized design for the space nodes of some historic streets.Firstly,based on the results of domestic and foreign research on suitability,combined with AHP and on-site investigations,this paper studies 17 specific images from five aspects of safety,comfort,communication,accessibility and recognition,optimizes the analysis model of aging,and constructs the quantitative analysis model of historical street space aging.The model data shows that the safety and comfort have a great impact on the level of space suitability for the elderly of historical streets.Then,based on the quantitative model,the paper concludes that there are some problems in Changsha historical street space,such as single function of communication space,low comfort of facilities,lack of intergenerational communication space,poor road traffic safety and so on.In this regard,based on the cultural advantages of historical streets and lanes and the current situation of their suitability for the aged,the paper refines the optimization objectives and Strategies of the Spatial Suitability for the aged of historical streets and lanes in Changsha;At the same time,based on the activity needs of the elderly in historical streets and alleys,starting from the four main street activity spaces of fitness,communication,leisure and viewing,and walking space,combined with the concepts of intergenerational mutual aid,function mixing,emotional design,and integration into street culture,this paper puts forward some optimization design examples for the elderly in some space nodes.This study provides data and optimization ideas for the current situation of Changsha historical street space,and also tries to provide more possibilities for the improvement and transformation of old city street space.
