| Under the current policy of "village and city symbiosis" in the current new urbanization stage,urban villages are no longer the "lost places" of cities to be demolished at any time,but will participate in urban development as a stable spatial component for a considerable period of time in the future.middle.As far as urban managers are concerned,the governance of urban villages can no longer be managed through demolition and non-demolition.Instead,they need to proceed from the actual needs of residents and use the value of space instead of transaction value as the primary governance policy.Point of departure.Incorporating villages in cities into the urban spatial governance system,by optimizing the functional structure of villages and cities,the overall spatial efficiency is improved and the sustainable development of the city is promoted.Therefore,there is an urgent need for corresponding spatial analysis methods and theories to analyze the distribution mode of urban elements and the internal mechanism of interaction under the influence of the village and city spatial structure,so as to provide a theoretical basis for the guidance and control of the spatial development of urban villages.In this context,starting from the practical needs of urban village space governance,taking the spatial vitality of village and city as the research object and supported by the research theories and methods of spatial vitality and urban spatial system,this paper aims to explore the specific ways of urban village to provide spatial place support for the development of residents’ daily social,economic and cultural life from the perspective of human land spatial relationship,This paper reveals the embedding mode of urban villages in the urban deep dynamic system and its role in promoting the construction of humanistic urban sustainable development capacity,so as to provide theoretical basis and empirical case support for the governance path of village city symbiotic space under the guidance of sustainable development capacity construction.Based on this,the paper carries out the research according to the logic of phenomenon characteristics → internal laws→ optimization approach,and takes small data and multi-source spatio-temporal big data as the data basis of the research."Phenomenon characteristics"-Taking mobile signaling big data as the core,this paper constructs a quantitative measurement model of multi-scale village city vitality spatio-temporal landscape characteristics based on vitality spectral line clustering,vitality group division and vitality structure identification.Through the measurement of multi-scale spatio-temporal landscape characteristics of Shenzhen village and city spatial vitality and its regression model analysis with vitality influencing factors,On this basis,the dynamic landscape distribution pattern of single element and multi element combination of village and city vitality is identified respectively.Among them,the neighborhood scale vitality characteristics reflect the shaping of residents’ living habits to the spatial significance of urban places,and the difference in the composition of local vitality types between Urban Village neighborhood units and other urban neighborhood units reflects the existing connotation of urban villages in the whole urban organism at the carrier level of residents’ activity places;The dynamic characteristics of cluster scale reflect the shaping of residents’ living habits on the significance of urban flow network space.The interaction mode between urban village space and other urban space in each dynamic cluster reflects the existence connotation of urban village in the whole urban organism at the level of residents’ activity field;The dynamic characteristics of urban scale reflect the shaping of urban dynamic spatial structure by residents’ living habits.The structural dynamic element attributes of urban villages in different locations reflect the existence connotation of urban villages in the whole urban organism at the level of urban activity system."Internal law"-this paper analyzes the deep law of the village city vitality system from the two dimensions of function and society.Functional dimension:Based on the central place theory,this paper constructs a quantitative analysis model of village city multi center system,and measures the central place system elements respectively on the basis of identifying the boundary range of urban employment center and life center.By deeply analyzing the specific distribution of village and city space in various levels of functional centers and various types of spheres of influence,this paper reveals the functional embedding path of village in city in the urban vitality system from the perspective of functional center and service hinterland.Social dimension: through the measurement and analysis of the spatial differences,agglomeration,co-occurrence,dependence and other social spatial agglomeration characteristics of the distribution of residents’ living activities such as residence,employment,consumption and leisure,this paper reveals the sustainability of the development of urban village settlements from the perspective of promoting the urbanization and integration of foreign population.urban village’s transformation strategy should be based on the exploration of the vitality model of the overall urban function that can be stimulated to the greatest extent under different vitality organizational structures.Combining the requirements of Shenzhen’s territorial space planning and the difference and complementarity model of village-city space vitality,the paper extracts an urban village with the transformation of youth public community in the central dynamic area,the stitching of diverse neighborhood units in the suburban dynamic area,and the low-cost entrepreneurial ecological base guarantee in the peripheral dynamic area.The development goal of vitality creation,from the perspective of optimizing the function of the vitality system of the village-city space and promoting the healthy development of the city,proposes strategies and measures for the reconstruction of urban villages,in order to respond to the actual needs of urban village space governance."Optimization approach"-As an organic part of the urban vitality system,the... |
