This study focuses on the reform of urban and rural planning practical teaching based on the multidimensional integration of government, industry, academia, research, and application. It is of great significance for deepening the comprehensive reform of territorial spatial planning and teaching, and for building a high-quality urban and rural planning teaching system. Guided by theories such as systems theory, the triple helix theory, and constructivism, this paper clarifies the ideas for multidimensional integration. Specific optimization strategies for the urban and rural planning practical teaching system are proposed from aspects such as optimizing the practical teaching curriculum system, promoting the construction of practical teaching platforms, and optimizing the organization modes of practical teaching. Ultimately, an optimization plan for the urban and rural planning practical teaching system is formed.
