MEASUREMENT METHOD OF URBAN BLOCK FORM BASED ON "ACCESS STRUCTURE"
In order to enhance the correlation analysis between physical form and behavior activity,this paper puts forward an"access structure"approach to quantitatively describe the morphological characteristics of urban block based on the topological connection among the three form elements of street,plot and building.The paper establishes a basic urban block structure and a cognitive concept of three types of complex structures:interlocking,concurrent,and overlapping,and proposes a complexity index system and its calculation method based on graph theory tools.By analyzing the internal composition logic of Gaoloumen block and the block type characteristics of three urban centers of Nanjing in different periods,it verifies the practicability and effectiveness of the method on two scales.It provides a scientific measurement method for the cognition of the inner organization logic of urban block morphological structure,and lays a technical foundation for the refinement and digital development of urban design at the micro level.
