Abstract: Strengthening the cultivation of students' professional accomplishment is a key strategy in the curriculum teaching reform of the Basic Landscape Architecture Design courses. After surveying of the subject, school operation, and course overview, this research analyzes the necessity of strengthening the cultivation of professional accomplishment in this course. Based on the analysis of the “knowledge internalization” principle in educational psychology, it puts forward the concept of internalized power of professional accomplishment and the feasibility of its cultivation. The research has discovered the main approaches to the cultivation of professional accomplishment with the Basic Landscape Architecture Design courses, and condensed them into the core link of “San Ming Yi An” teaching with the three dimensions of professional skills performance, thinking creation, and knowledge control as the superficial training routes and the internalization of professional accomplishment as the concealed training route, and built a teaching system based on this. The teaching system is based on the superficial training routes, supporting the vertical axis of ability training, and the concealed training route as the core, connecting the horizontal axis of time in series with five modules and five stages. It further sorts out the key points of superficial training routes and concealed training route and its guarantee mechanism. The construction of this teaching system is guided by strengthening the internalization of professional accomplishment. It has a considerable reference to the teaching reform of the corresponding strategy of Basic Landscape Architecture Design courses.
