Research On Ancient Li-fang System And Future Productive City Hierarchy System

Since the thought of “post-industrial society” has been widely spread,the rise of the tertiary industry and the convenience of transportation have weakened the thinking of planners and architects on the basic order of the city.The idea of “automobile city” that excessively expands traffic resources leads to the homogenization and fragmentation of urban structure.The urban spatial structure is complex and fragile.The urban social structure is constantly in conflict with the rapid development of human production,life and ecological requirements.The construction of future residential pattern needs to find urban order urgently.Based on the theoretical knowledge of urban order at home and abroad,this paper refines the order prototype of Li-fang city hierarchy system,introduces the concept of productive city,and constructs the future productive city hierarchy system in order to form a reasonable urban spatial and social structure and organize urban order.The hierarchical system of Li-fang city presents a clear fractal spatial structure,and at the same time clearly reflects the isomorphic social order,supporting the hierarchical and orderly development of urban structure.Inheriting and innovating the traditional urban hierarchy system.From the perspective of urban design,this paper analyzes the urban style and features derived from the connotation of the Li-fang unit system,stresses that the urban spatial structure must contain three elements,namely,the core,the boundary and the network,and puts forward specific construction strategies.The basic hierarchical units of the productive city spatial structure are formed with three elements,and each hierarchical unit is advanced.Finally,a physical form model of productive city hierarchy system is generated.From the perspective of social anthropology,this paper analyzes the requirement of sustainable development of human society,refers to the operation method of Li-fang unit system,and establishes an abstract social mechanism model of productive city hierarchy system,which fully includes reasonable social production mechanism,social life mechanism and social ecological mechanism.With the construction method of ancient Li-fang city hierarchy system,the future productive city hierarchy system is mapped and its practical significance is discussed.On the one hand,the inheritance and innovation of traditional urban planning method in modern times can be realized,on the other hand,the future urban order development has been explored completely,and a new idea for the future research of human settlement pattern theory and practice has been provided.
