Research On The Evaluation And Design Of The Vitality Of The Historical Commercial Street Space In Xizhong City,Suzhou

Under the background of urban stock renewal and refined design,historical commercial streets have become an important part of urban public space,and play an irreplaceable role in the vitality of the entire city.The vitality evaluation system of historical commercial streets is becoming increasingly complex,and the advent of the era of "big data" creates a new and quantifiable dimension for human life with its diversity,high speed,massiveness and low value density of data analysis and dissemination,and data analysis has become an important criterion for establishing a spatial vitality evaluation system of historical commercial streets,so as to help us analyze problems more accurately from the objective environment.Based on the research background described above,this paper attempts to intervene from the perspective of the external spatial vitality and crowd vitality characterization of historical commercial streets,relies on the research of relevant scholars on the spatial vitality of historical commercial streets,and uses multi-source geographic big data analysis such as mobile phone signaling and POI data to obtain the gathering density,functional mixture,spatial distribution of supporting facilities,etc.,taking the historical commercial street and surrounding spaces of Xizhong City,Gusu District,Suzhou as an example,and proposes to construct an "environment-crowd" vitality evaluation system for the subject and object that affect vitality.Through the questionnaire survey with the participation of experts and the public,using the analytic hierarchy theory,the use of historical commercial streets is explored from a micro perspective and its vitality is evaluated and studied,and the influence of historical commercial street space and crowds on the temporal and spatial differences of crowd vitality is discussed from the dual dimensions of crowd vitality characterization and spatial environment,and an optimization strategy is proposed to improve the vitality of historical commercial streets,the whole article is divided into four parts:Basic theoretical research.By sorting out the concepts of historical commercial streets and street spatial vitality by relevant scholars,the background and development status of historical commercial streets are summarized as a whole,and the problems existing in historical commercial streets in the new development stage of urban renewal are proposed.Through the definition of concept and the definition of the spatial scope of the research area,the research purpose of this paper is clarified by combining relevant theoretical research,and the advantages brought by multi-source geographic big data to the analysis and design of the spatial status of historical commercial streets are clarified.Construction and application of evaluation system.By pointing out the shortcomings of the existing evaluation system for the spatial vitality of historical commercial streets,analyzing the influencing factors of the spatial vitality of historical commercial streets,and using the Analytic Hierarchy Process to divide the spatial vitality of the region into three main dimensions: spatial environment,event environment,and vitality characterization.At the macro level,using big data for objective analysis,a historical commercial street spatial vitality evaluation system is constructed.Select the historical commercial street and surrounding spaces in Xizhong City,Suzhou as the research object of this article,use expert scoring,and use Analytic Hierarchy Process to obtain the weight of the vitality evaluation of the historical commercial street,and obtain an expert attention rating.And a comprehensive overlay analysis was conducted on the expert attention obtained in the spatial vitality evaluation system of this article and the satisfaction level of respondents with the use of historical commercial streets in Xizhong City,pointing out the influencing factors of insufficient vitality in Xizhong City at the current stage;Design principles and strategies.Finally,based on the analysis results of the evaluation system for the vitality of the historical commercial street space in Xizhong City,Suzhou and the obtained weights,this article reclassifies the evaluation index factors into four types,proposes a focus on the "high attention low satisfaction" factor,gradually improving the vitality optimization suggestions of the "low attention low satisfaction" and "low attention high satisfaction" factors,and continuously maintaining the "high attention high satisfaction" factor,And propose targeted and precise strategies.Design Practice.In response to the update of the "high attention low satisfaction" factor,it is advocated to create themed nodes,shape distinctive entrances and exits,optimize the waterfront and shoreline of the site,etc.In response to the "low attention high satisfaction" factor,it is proposed to build a characteristic slow moving system and strengthen the construction of supporting facilities.In addition,in order to enhance spatial vitality through historical scene reproduction,diversified function placement,and virtual experience design for the "low attention low satisfaction" factor.The aim is to provide appropriate theoretical basis and practical reference for improving the environmental quality of historical commercial streets of the same type in the old urban area of Suzhou.Construction of evaluation system.By pointing out the shortcomings of the existing historical commercial street spatial vitality evaluation system,the influencing factors of the spatial vitality of the historical commercial street in Suzhou Xizhong City are analyzed,and the spatial vitality of the area is divided into three main dimensions of spatial environment,event environment and vitality characterization through the analytic hierarchy method,and the objective analysis is carried out by using big data at the macro level,so as to construct the spatial vitality evaluation system of the historical commercial street in Suzhou Xizhong.Empirical Research.The historical commercial street and surrounding space of Suzhou Xizhong City were selected as the research object,and the factors in the evaluation system were analyzed by big data,and the score and weight of the vitality evaluation of the historical commercial street in Suzhou Xizhong City were obtained by the analytic hierarchy method,and the expert importance rating was obtained,which was comprehensively analyzed with the satisfaction results of users after the use of the historical commercial street in Xizhong City at this stage,and the reasons for the lack of vitality of the historical commercial street in Xizhong City were found in the stage.Compared with the traditional vitality evaluation system,this method has the advantages of a wider perspective,more macroscopic and more accurate data.Design strategies and practices.Finally,according to the analysis results of the spatial vitality evaluation system of historical commercial streets in Xizhong City,Suzhou and the weights obtained,this paper reclassifies the evaluation index factors into four types,puts forward the vitality optimization suggestions focusing on the "high attention-low satisfaction" factor,gradually improves the "low attention-low satisfaction" and "low attention-high satisfaction" factors,continuously maintains the "high attention-high satisfaction" factor,and puts forward accurate and effective strategies for the "high attention-low satisfaction" factor.Based on the above analysis results,the design based on strategic analysis aims to provide appropriate theoretical basis and practical reference for the improvement of the environmental quality of the same type of historical commercial street in the old town of Suzhou.
