Existing methods for urban expansion boundary delimitation face numerous limitations, such as neglecting ecological needs, lacking mechanisms for interest coordination, and insufficient supervision, making it difficult to achieve sustainable development. This paper proposes a boundary delimitation strategy based on the principle of ecological priority, emphasizing the improvement of policy and legal frameworks, establishment of interdepartmental coordination mechanisms, introduction of scientific monitoring and evaluation systems, and enhancement of public participation to optimize urban expansion boundaries. Practical case studies have verified the significant effectiveness of this strategy in ecological protection, improvement of land use efficiency, and socio-economic development, providing valuable theoretical support and practical guidance for sustainable urban development.
