Based on the background of new engineering construction, this paper proposes that the graduation design of urban and rural planning major in local universities should embody the curriculum goal of "four in one" comprehensive creative ability. Then, the model of "multi-subject collaborative education" is applied to the "7+1" joint graduation design teaching practice of the national urban and rural planning major, and the implementation measures of graduation design teaching reform are elaborated from the aspects of inter-school collaboration, intra-school collaboration, school administration, enterprise community . Finally, the improvement strategy of joint graduation design for urban and rural planning majors in the context of new engineering construction is proposed in order to provide new ideas for the reform of graduation design teaching in local universities and boost the reform and innovation of urban and rural planning education in the context of new engineering construction.
