Evaluation Of Urban Vitality Space The Main Urban Area Of Huining County Based On Multiple Data

As China’s urban development process into the connotation promotion stage,the development of people-oriented value core will further guide urban development,improve the quality of urban development,strengthen the intensive use of land,the construction of vibrant city become a common goal at home and abroad,due to the development of Internet technology,urban planning and spatial analysis has more new methods and ways.Especially in the utilization and development of big data and spatial analysis technology in recent years,It can monitor the urban operation state and the spatial and temporal behavior of urban people in real time,Such as Baidu heat map,mobile phone signaling,remote sensing data,Baidu Street View and other location-based service platforms,These data can effectively record the time and spatial location of the activity of people in the city,It can more specifically reflect the multiple activities of people in the city within the urban scope,To provide new data support and new research direction for the current research of urban vitality and vitality space in cities,Reshaping the urban space,Improve the quality of the city,Create a livable environment,It is a key means to promote sustainable urban development.Therefore,considering the diversity and complexity of spatial vitality based on the theory of urban vitality,we can consider the two dimensions of external performance and internal components,and determine the content of the evaluation —— the link of traffic ——;the traffic environment —— the occurrence of vitality;the evaluation index of spatial vitality and the corresponding evaluation quantification method,and finally determine the evaluation system of spatial vitality in this paper.According to determine the evaluation system to huining city dynamic space as the research object,through baidu heat map,POI,urban road network multiple data on the basis of data,using Arc Gis,space syntax and Excel data analysis processing tools of the vitality of the elements of quantitative analysis and qualitative comparative analysis.The research shows that: in terms of the external representation dimension of vitality,no matter on working days or rest days,the areas with high vitality intensity are always concentrated in Beiguan Square,Union Park,Huifu Square,New Market and near blocks.The change law of activity intensity is similar,but the overall change law of rest days appears later.In the dimension of constituent elements: from the perspective of location conditions,the dynamic space blocks have good accessibility and passability;traffic organization,since the part of the area needs to optimize and improve the overall transportation system due to the lack of understanding in the spatial environment of the city,there are many functional forms in the main dynamic space of the city,but the distribution is uneven.Based on the above analysis results,it is of great practical significance to explore the formation mechanism and construction strategy of urban vitality under the current situation of stock development,and to promote the healthy development of urban space.
