Abstract: Blocks and plots are important elements of microcosmic urban fabric, and the analysis of their morphology can reveal the mechanism of urban planning. Taking the former French concession in Tianjin as the research object and using urban morphologic theories, this paper explores the planning characteristics and mechanism of Tianjin in a microscopic scale by analyzing the numbering and subdivision of the blocks and plots in this area. Firstly, this paper discusses the numbering of the blocks and plots, pointing out that the old town of Tianjin, the Haihe River and Dagu North Road are the major factors influencing the planning of the former French Concession. Secondly, by studying the plots and analyzing the subdivision of the plots, this paper summarizes the open characteristics of the former French concession towards the former Japanese and British concessions. Based on urban morphology and urban historic landscape theories, this paper contributes to supplementing studies on Tianjin's modern urban planning and provides the basis for future overall protection of cities and the formulation of regeneration strategies.

摘要： 街廓与产权地块是微观城市肌理的重要组成要素，对其形态的分析可揭示城市规划机制。研究运用城市形态学的方法，以天津原法租界为研究对象，通过对街廓及产权地块编号及划分的分析，从中微观尺度上考察天津的规划特征及机制。首先对天津原法租界的街廓和产权地块编号进行探讨，指出天津老城、海河及大沽北路等是影响天津原法租界规划的重要因素；其次是对产权地块的研究，通过对产权地块划分的分析，得出原法租界面向原日、英租界开放的特征。研究立足于城市形态学及城市历史景观的理论基础，是对天津近代城市规划研究的补充，亦可为未来城市整体保护和再生策略的制定提供依据。
