The Urban History courses contents a lot of detailed knowledge within a huge spatial and temporal span, so that relying on the chronicle-based structure of the current textbook alone is not enough to enable students to form a systematic knowledge system, grasp the development of urban history deeply, and connect historical knowledge with current design needs. With reference to the knowledge system framework in the current Architectural History courses and textbooks, which takes chronicles and building function types as two axes, this paper proposes to add an axis of city types in the teaching structure of Urban History, classifying and comparing cities in different eras and regions, and forming a multidimensional knowledge system that intersects with the main line of chronicles. This paper than analyzes the characteristics of various city types in important urban studies in China and abroad, as well as the methods of integrating them into the knowledge system. These city types including the types of cities based on time, morphology, geography, population size and function. This paper points out that various city types should be integrated according to their respective characteristics to form a "city type knowledge system" that takes into account the strengths of each. According to the analysis in the paper, the type based on time is the basis of the knowledge system. The type based on morphology and the type based on geography are suitable for the axis of the knowledge system. The type based on population size is suitable for the introduction of the course. And the type of function is suitable to be applied in teaching specific city examples. Based on this analysis, this paper proposes a specific knowledge system framework with the three main axes of city types of times, morphology, and geography, which can be applied to the teaching of Urban History courses.
