天津是近代中国开埠较早、设立外国租界最多的城市，随着西方建筑工业体系的引入，租界区不断开发建设，形成了独具特色的城市风貌。在此过程中，材料作为建筑最基本的物质元素，其运用和发展成为推动近代建筑演变的重要动因，直接影响着城市风貌的形成。本研究以天津近代租界区建筑材料为研究对象，通过史料挖掘与实物遗存调研，对材料的生产背景、基本性质、加工技术和施工工艺进行研究，建立天津近代租界区建筑材料运用信息数据库。在此基础上，对材料在建筑上的运用展开专项研究，进而综合分析其整体发展轨迹、基本特征和背景动因，揭示天津近代租界区建筑材料运用的发展演进。与此同时，建构建筑材料与城市风貌的对应关系，探究其间蕴含的制度、技术、观念层面的内涵，提出天津近代租界区建筑材料运用对城市风貌的影响机制。以期丰富中国近代建筑史研究，为建筑遗产保护提供科学依据，为城市风貌研究提供新视角。

Modern Tianjin was opened early and had the most foreign concessions in modern China. With the introduction of Western construction industry system, a large number of modern buildings were constructed in the concessions, forming a unique cityscape. As the basic element of a building, the material was an important motivating factor, which drove the evolution of modern architecture and influenced the formation of cityscape. The project takes the building materials in modern Tianjin as the research object. Based on the exploration of archives and the investigation of historical remains, the project researches on the manufacturing backgrounds, basic characters, processing technologies and construction crafts of the building materials, and establishes the database. By researching the application of materials in the building according to its classification, the project analyzes the development processes, features and backgrounds of the application comprehensively, and presents it in a tabular form. On this basis, the project analyzes the correspondences between building materials and cityscape, explores the underlying causes behind the relationship with the perspectives of system, technology, idea, and attempts to reveal the influencing mechanism of the building materials on the cityscape. Based on the above, the research field of modern Chinese architectural history is expanded, the scientific basis is provided to modern architecture heritage protection, and a new perspective is introduced to the research on cityscape.
