Research On Spatial Morphology Of Tianjin Italian Style District Based On Data Analysis

The era of big data has brought new opportunities.Diverse data analysis provides new technical methods for the analysis of urban design and construction.China has changed from incremental planning to stock planning since 2015.As the main section of stock planning,historical and cultural blocks still have much room for improvement in quantitative and technical aspects in related research.The application of multi-source data can be used as a historical and cultural block research A new discussion and method.With the precipitation of time and history and culture,the historical and cultural districts have formed unique spatial forms,architectural forms and humanistic environments.Due to the difficulty in taking data,the previous research on historical and cultural blocks tended to focus on qualitative analysis,focusing on the inspection and protection of individual buildings and physical spaces,and less research on spatial vitality,ignoring the value of the spatial form itself.The subject research aims to make up for the above-mentioned shortcomings,based on field surveys,based on the integration of multi-source data,introduces spatial syntax theory,combines POI and GIS spatial analysis technology,and relies on the space protection and update practices of Italian style areas in recent years.Based on the analysis,macro-spatial integration,selection,intelligence,and other syntactic variables,meso-network geometry and micro-line-of-sight connection values,integration,clustering values,intelligibility,and other variables affect street and lane spatial shapes.The structural characteristics and vitality are systematically analyzed and researched,and the internal and external space shapes and vitality of historical and cultural blocks are explored.The public vitality,functional layout and flow distribution are used to verify the spatial vitality.Furthermore,the correlation and comparative analysis of the density and integration degree of street segments,and the distribution and integration degree of crowd activity places were made respectively to obtain the coupling relationship between spatial form and vitality.As a basis for testing whether the spatial form is reasonable,the spatial form and Correspondence between social representation and vitality,and put forward opinions for the development and construction of historical and cultural blocks.Finally,based on the detailed theoretical research data and technical route obtained from the data analysis,it is proposed that the improvement of the spatial form and optimization of the Italian style area and related historical and cultural blocks from the three aspects of spatial form,vitality factors,and the vitality level of the spatial form are operational Strategies for sustainable development.
