| Since the reform and opening up, with the rapid development of China’s urbanization, regional economy and traffic have occurred great change. At the same time, China’s urbanization also gave birth to a number of mega cities, that show the trend of multi centers in the development of space. And these mega cities appear local urban area of three-dimensional space highly polarized characteristic.which is "urban clusters". Urban spatial clusters is the high density area of urban spatial elements, and it is the gathering place of high-profit service industry in the city, and it is the most active area in the city. In this paper, based on spatial shape data and cellular signaling data, combined with the case of Shanghai City, cluster space dynamic static characteristics and structure for quantitative analysis will be researched.What’s more, the characteristics,spatial structure and rules of spatial clusters and will also be summed up,that will thereby further help us know urban spatial clusters.First of all, this paper in Shanghai district development intensity of urban intensity gradient layers will be divided, through quantitative data operations defined Shanghai cluster space scope.And then,I will summarize the spatial clusters of basic features, the basic classification, Shanghai space cluster system, which is an important preliminary foundation of the research.Next, through ArcGIS platform of spatial network analysis,I will use isoline method, clustering method, circle method and sector method,space syntax method,the distribution of the space of the cluster space and morphological characteristics.And then I will conclude static characteristics of the spatial clusters. Then, through the mobile phone signaling data of Shanghai, analysis of population activity patterns in Shanghai will be studied, and the dynamic spatial structure of Shanghai spatial clusters will be summed up. Finally, in the perspective of the elements of Shanghai city spatial form and structure,Shanghai city spatial morphology structure model will be constructed. |
