In order to enhance emergency response capabilities and the service efficiency of shelter systems in rural areas, this study adopted an optimal supply-demand allocation model integrated with Geographic Information System (GIS) software (ArcGIS) to evaluate the accessibility of village-level emergency shelters and township-level short-term shelters in northern Henan province. Key factors influencing shelter site selection were identified to construct a spatial suitability evaluation index system. Using this system, we assessed the spatial distribution of emergency shelters in Xicun town and proposed optimization strategies for the shelter system. The results reveal a significant supply-demand imbalance characterized by poor accessibility, partial overload of village-level shelters, and an irrational distribution with severe shortages of township-level shelters. The suitability evaluation indicates a clear north-south disparity, with higher suitability in the south. After implementing optimization measures—including adding village-level shelters and upgrading those in highly suitable areas—both the balance between supply and demand and overall accessibility are improved across the two-tier shelter system in Xicun town.
