Under the background of national "double first-class" construction, first-class undergraduate curriculum construction has become an important way to cultivate high-quality talents and promote educational reform.The discipline of urban design has the characteristics of integration and synergy, and plays an important role in guiding the construction of high-quality human living environment. However, urban design education has started late in China, and its development still faces problems of unclear objectives, mixed systems and different standards. Based on the advantages of traditional architecture disciplines, the specialized teaching of urban design in the School of Architecture of South China University of Technology insists on several goals, such as comprehensively cultivating students' ideological and political literacy, international vision, professional knowledge and innovation ability. After more than 20 years of construction and reform, it has established a relatively complete and high-level teaching system. It has been awarded the second prize of National Teaching Achievement Award, the first batch of first-class undergraduate courses by the Ministry of Education, the first batch of pilot recognition of virtual teaching and research room construction by the Ministry of Education，the list of the first batch of online model courses for postgraduate students of Master of Architecture degree in China and so on. Architectural Design (V-VI) (specialisation in Urban Design) takes the reform path of "broadening the professional foundation" and "deepening practical research" to create a design teaching model of "high-level international cooperation + multidisciplinary synergy + integration of learning, research and production". It has already achieved good results in the cultivation of innovative talents in urban design. In order to provide reference for the teaching reform of urban design courses, this paper introduces the construction objectives of the first-class undergraduate courses, the construction and application of the courses, the characteristics and innovation of the courses, the construction plan and the construction effect and so on.
