This book presents the latest research results related to urban center and urban center . It expounds the theoretical connotation, development models, hierarchical function, and spatial layout of the urban centrality structure through over 200 figures and tables. In addition, it analyzes the threshold characteristics, structural hierarchy, spatial characteristics, and development rules of urban centrality structure through field research and quantitative researches on the major urban centrality structures in Asia. Meanwhile, how to solve the issue of construction and layout of urban centrality structure in planning and design practice is also covered. The book reveals the laws and spatial characteristics of urban centrality structure and provides a valuable guide both for urban designers and planners as well as researchers and students working in urban design and planning fields. It sheds new light on better understanding of the urban centrality structure.
