Research On The Perception And Construction Of Handan’s Urban Style Based On Multi-source Data

The urban style is the organic unity of the external form and the internal spirit of the city,and it is an important feature of the long-term development of the city.Modern cities are in the stage of transition to high-quality development.Rapid urbanization has brought about problems such as homogenization of style,lack of features,and destruction of regional context.The problem of urban style needs to be solved urgently.At present,the work of urban style planning and guideline compilation in my country is relatively mature and effective,but the perception of large-scale urban style and the grasp of the spatiotemporal distribution of urban style is slightly insufficient.With the deepening of urban style research,the rise of urban computing research,and the development of data science and computer science,multi-source data provides new ideas and methods for urban style research.In this context,taking the perception and construction of urban style as the research content,firstly summarize the relevant theories and research trends of urban style at home and abroad,clarify the concept and composition of urban style,and explore its coupling relationship with multi-source data.Starting from the physical and non-material environmental elements,the urban style is divided into four components: the overall urban style,the urban spatial structure,the urban architectural style and the urban humanistic style.Analyze urban style perception factors,and use multi-source data combined with traditional data,comprehensive human and land data(population heat map,building data,POI data),street view image data,and Weibo check-in data to build an urban style perception and construction system.Taking the urban style of Handan as the research object,selecting the main carrier of the urban style and the main urban area as the research scope,perceiving the urban style of Handan based on multi-source data,and obtaining the overall characteristics of the natural landscape,urban pattern and historical context of the main urban area of Handan through traditional data.Handan city portrait,excavate the characteristics of the city’s features;obtain the characteristics of population vitality distribution,land plot development,regional core and other characteristics through the comprehensive data of human and land industry,and explore the urban spatial distribution and aggregation form;extract the city’s eleven types of architectural features through street view image data,get the spatial layout and visual features of the building;get people’s feelings about the city through Weibo check-in data.Finally,the urban style of the main urban area of Handan City is constructed from the systematic organization of urban style and the level of micro-units.Taking the urban style of Handan as the research object,selecting the main carrier of the urban style and the main urban area as the research scope,perceiving the urban style of Handan based on multi-source data,and obtaining the overall characteristics of the natural landscape,urban pattern and historical context of the main urban area of Handan through traditional data.Handan city portrait,excavate the characteristics of the city’s features;obtain the characteristics of population vitality distribution,land plot development,regional core and other characteristics through the comprehensive data of human and land industry,and explore the urban spatial distribution and aggregation form;extract the city’s eleven types of architectural features through street view image data,get the spatial layout and visual features of the building;get people’s feelings about the city through Weibo check-in data.Finally,the urban style of the main urban area of Handan City is constructed from the level of urban style system,organization and unit.
