Research On The Cultural Image Of Chinese Cities Based On Multi Source Data

Urban cultural image refers to the urban cultural system as a representation of a city,including material and non-material aspects.The material level includes: the city’s spatial layout,architectural style,green environment,etc;The non-material level includes: Urban publicity,historical and cultural traditions,economic development,etc.A good cultural image of a city can enhance its attraction,competitiveness and economic and social development.Based on the importance of urban cultural image to urban development,this paper makes a quantitative analysis of urban cultural image by using multi-source data from the perspective of urban and rural planning.The core content of the article is divided into three parts.The first part is the research method and the target city.(1)From the research results of the quantitative study on urban culture,six cities(Beijing,Shanghai,Guangzhou,Hangzhou,Nanjing and Tianjin)which are recognized as the top cities in the city culture ranking are selected as the research objects.The research scope is the construction land of the downtown area.(2)Through statistical analysis of the literature on "urban cultural image",the relevant keywords of urban culture are extracted,and the extracted keywords are the theme.Through a large number of literature reading,a comprehensive quantitative evaluation factor database of urban cultural image is obtained,and 186 factors are finally evaluated.Based on the selection principles of scientific,feasible and objective indicators,38 primary indexes were obtained by screening the evaluation factors.(3)This paper analyzes and summarizes the classification of urban cultural image evaluation dimension in the study of urban culture.Combined with the research scope of this paper,the evaluation factors are classified into two categories: urban cultural facilities dimension and urban characteristic style dimension.In the second part,based on the classification of the evaluation factors in the first part,the evaluation factors of the two dimensions are assigned,and the urban cultural image of the research object city is analyzed.(1)This paper analyzes the layout of urban cultural facilities,analyzes the quantitative assignment methods in the relevant research results,combined with the characteristics of cultural facilities dimension evaluation factors,selects Arc GIS to do the core density analysis and buffer analysis,and further calculates the analysis results to get the assignment results.(2)According to the relevant research of urban landscape evaluation,the evaluation factors are comprehensively sorted out,which are divided into traditional historical landscape,modern port opening landscape and modern urban landscape.The traditional history and modern port opening style take the historical and cultural blocks as the research object,take the style atmosphere level,space texture preservation degree,architectural style,architectural regionality as the evaluation factors,and adopt the quantitative and qualitative combination method to quantify the assignment.Modern urban landscape takes super high-rise buildings as the starting point,quantifies the ratio of the overall scale to the city scale,and reflects the influence of super high-rise buildings.The third part is the analysis result of city cultural image.The evaluation results of evaluation factors are dimensionless processed by extreme value method.The entropy method is used to give weight to the evaluation factors of cultural facilities layout dimension and urban features dimension,and the final quantitative index system of urban cultural image is obtained.The final quantitative index system is used to rank the cultural image of the above six cities: Beijing,Nanjing,Hangzhou,Shanghai,Tianjin and Guangzhou.There is a certain coupling with the ranking of other researchers,which shows that the index system is reasonable.
