Research On The Public Space Evaluation System Of Historical And Cultural Blocks Based On Interaction Theor

As the carrier to track the process of urban development,the public space of historic district gathers the context of the city and shows the unique urban image.Most historical and cultural blocks focus on functional layout and spatial modeling,but ignore the perceptual interaction of "human" as the main user in the public space.How to use Internet big data,Arcgis,mobile Search method(2SFCA)and other technical means to conduct quantitative analysis of public space based on people’s behavioral needs is an urgent problem to be solved in the protection and utilization of historical and cultural blocks.Firstly,this thesis reviews relevant domestic and foreign achievements,and clarifies the relationship between public space and interaction theory through relevant studies on interaction theory and evaluation of historical and cultural blocks,providing theoretical basis for subsequent studies.Secondly,an interactive evaluation system was constructed.The five evaluation indexes were visual perception awareness,spatial facility support,architectural landscape satisfaction,spatial communication and spatial mobility.The AHP was used to determine the weight of each index and the fuzzy evaluation model.Then,taking Baihua ZhouFurong Street historical and cultural block as an example,the evaluation data was obtained by means of data crawling and questionnaire survey.Arcgis,Depthmap,SD and other analysis tools were used for model calculation.Based on the results,the current situation and influencing factors of historical buildings and public Spaces were analyzed.Finally,based on the fuzzy evaluation analysis of interaction,interactive promotion strategies are proposed respectively from the surface,new media and space levels to provide reference for the protection and renewal of historical and cultural blocks.
