摘　　要：为了加强物质形态与行为活动的关联性分析,本文基于街道、场地和建筑三种形态要素之间的拓扑连接关系,提出量化表述城市街区形态特征的“入径结构”方法。建立了街区基本结构以及互锁、并合、套叠三种复杂结构类型的认知理念,基于图论工具提出复杂性指标体系及其计算方法。以南京为例,通过分析高楼门街区的内部构成逻辑,以及不同时期的三个城市中心区的街区类型特征,验证了该方法在两个尺度上的实用性与有效性。为认知城市街区形态结构的内在组织逻辑提供了一种科学的测量方法,也为城市设计在微观层面的精细化和数字化发展建立了技术基础。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.
