By investigating laboratories of some art and architecture design universities including Tsinghua University and Tongji University, and discussing the teaching research with more than 30 colleges and universities in western China, the characteristics of the construction and practice of the experimental teaching system are analyzed comprehensively. Combining the actual situation of regional development in western region, we make recommendations for explore the features of experimental teaching of design, such as experiment teaching target localization, experimental projects being flexible and innovative, setting up the experimental teaching service team reasonably, optimizing the experiment appraisal system, creating "green lab", expanding external communication, and the opening of general courses.
