基于复杂网络的西安主城区空间结构研究
Research on the Main Urban Area Spatial Structure of Xi'an Based on Complex Network
摘要
Abstract
Taking the main urban area of Xi'an as the research area,we used OSM road data,and analyzed the spatial structure by calculating the road network density and identifying multi-level road communities.The results show that①from the overall spatial perspective,the road net-work development level in main urban area of Xi'an is relatively high as a whole.The road network is centered in the old urban area and gradual-ly expands to the outer circle in the northern area of main urban area.②From the global scale,the urban area of Xi'an shows the urban structure of the common development of multiple centers.The old urban area and the surrounding districts interact with each other,forming a new spatial distribution structure of roads,which gradually expands from inside to outside,dispersing the urban center and forming multiple centers.③From the local scale,except Chang'an District,the internal development of each district is balanced,with Beilin District,Xincheng District and Lianhu District as the center,and the development of outer circle,showing a spatial structure of the center is strong and the outer circle is weak.关键词
