Measurement Of Vitality Of Commercial Streets Residential Areas In Qingdao From The Perspective Of Physical Space

In the course of rapid urbanization,the loss of street space quality and the vitality of the city have been observed.At present,after experiencing high speed development,the city gradually moves towards the pursuit of high-quality development,the living standard of residents also rises,and the demand for quality of life also increases correspondingly.Therefore,improving the quality of street space and enhancing street vitality has become an important issue facing the city.This paper studies the vitality of commercial streets in residential areas from the perspective of material space,taking the "meeting room" in the city and the "fireworks" place closest to residents’ life as the research object.This paper attempts to propose feasible vitality measurement system and vitality enhancement strategy for residential commercial streets in the important period of urban renewal and transformation in the post-epidemic context,so as to optimize street spatial quality and improve residential happiness.First of all,through the study of domestic and foreign scholars’ literature and relevant norms,the concept of residential commercial streets,street vitality and street commerce in residential areas is defined,the research target is defined,the relevant theories of street vitality and residential commerce are summarized,the relationship between "street,residential area and street commerce" is clarified,and the rationality and feasibility of the research direction is proved.Secondly,by drawing on previous theoretical research results and integrating the characteristics of research objects,an index system for measuring the vitality of commercial streets in residential areas is constructed,which is divided into two dimensions: the external representation of street vitality and the spatial carrier.According to the concept definition of street vitality,the external representation of street vitality is divided into two parts: crowd and activity.Starting from the composition of street material space,the space carrier of street vitality is divided into three parts: environment space,building interface and bottom interface.Then,two residential areas in the quality improvement stage and intensive development stage of Qingdao residential areas are selected,namely Fushanhou area and Xinduxin area.Six typical residential commercial street segments are selected in each area,and field survey is conducted by using field measurement,video recording,resident interview and other methods to conduct empirical quantification of vitality measurement of the selected street segments.The correlation analysis and regression analysis were carried out between the external representation index factor of street vitality and the spatial carrier index factor,to explore the spatial influencing factors of the vitality of residential commercial streets,and to make a comparative analysis of the residential commercial streets constructed in different periods.Finally,based on the analysis results of factors affecting the vitality of commercial streets in residential areas,combined with the excellent street renewal cases in other cities,the principles and targeted strategies for enhancing the vitality of commercial streets in residential areas in Qingdao are proposed.The research results show that the spatial factors influencing the vitality of commercial streets in residential areas in Qingdao are more diverse,among which the main factors are street building interface and bottom interface space,and the factors influencing the vitality of commercial streets in residential areas in different construction periods are also different.The vitality of residential commercial streets in residential areas constructed in the quality improvement stage of Qingdao residential areas is mainly affected by the transparency of commercial interface,density of commercial interface,density of public facilities,mixing degree of business forms and width of frontage area.The vitality of residential commercial streets in residential areas constructed in the intensive development stage of Qingdao is mainly affected by the transparency of commercial interface,the density of public facilities and the width of frontage area.Therefore,this paper starts with the five measurement indicators of the vitality space carrier of residential commercial streets--three-dimensional spatial form,environmental comfort level,commercial format,commercial interface form and walking comfort level,and proposes street vitality enhancement strategies.According to the analysis results,different targeted strategies are proposed for residential commercial streets in different construction periods within the same measurement index.It is expected that this study can provide reference suggestions for improving the vitality of commercial streets in residential areas of Qingdao,reshape the vitality of streets,improve the quality of life of residents,and as a catalyst point,help residential renewal and urban renewal in Qingdao on a larger level.
