Spatio-Temporal Change Of 3D Urban Architecture Morphology Based On UDEM

At the moment,our country is entering a critical period of urbanization.In the past,people have been more focused on urban sprawl,ignoring the city's spatial features.More and more researchers have begun exploring the city's spatial structure.In contrast to the rapid economic growth of urban development,the harmonious development of urban ecosystems is an important aspect of future national construction.Currently,urban vertical planning and analysis are lacking integrity and science,making urban space an irregular and disruptive development in urban sprawl.Therefore,according to the status and research progress in the urban space in our country,put forward the concept of " 3D Urban Architecture Morphology".The 3D Urban Architecture Morphology is formed by the spatial Morphology of various artificial buildings,which are characterised by changes in spatial patterns that have been shown in urban development.It not only includes the spatial form of urban architecture itself,but also reflects the social forms of human activity.There are distinct regional differentiation characteristics in the form of 3D Urban Architecture Morphology.In the meantime,urban architecture has a strong complexity,similarity,diversity,and selforganization.Deep exploration of 3D Urban Architecture Morphology is a way of understanding the laws of evolution in the depths of space.The definition of 3D Urban Architecture Morphology provides scientific basis for the layout and planning of urban space further enriches the theoretical basis for urban space.In the study of 3D Urban Architecture Morphology,this article builds a quantitative measure of the three-dimensions of urban architecture.And improved the original research unit,fully considering the way the road and street of city divide the city's space.The basic unit of the city's urban block,with Spation-Temporal analysis of 3D Urban Architecture Morphology;Based on the Kriging interpolation method,a trend analysis of three-dimensions of the city's architecture analyze their progress and trends in one space and dig inside the internal rules and overall features of the three-dimensional buildings.Introduction of Moran's I index analysed the spatial nature of the three-dimensional architecture of the city.This paper analyzes the variation pattern and autocorrelation characteristics of urban architecture spatial form in the study area in 2005,2010 and 2015 from different perspectives.The evolution of spatial and temporal changes can reflect the regional characteristics of urban spatial differentiation and self-organization summarize the historical development of the city.It reveals the change pattern of urban spatial form in the process of urban development,and provide reference for future urban planning and design prototypes and theoretical foundations.
