With the reform and continuous improvement of the national reserve system, the storage capacity of reserve warehouses, which serve as important carriers for safeguarding national and emergency materials, has become especially important in the new era. The study first analyzed the current storage status of reserve warehouses, pointing out problems such as low land utilization rate, limited warehouse capacity utilization, high inventory occupancy rate, diverse demand for inventory materials, and uneven level of information technology application. In response to the above issues, with the goal of improving the warehouse capacity of the reserve warehouse, three directions of improvement are proposed: expanding the storage capacity of the reserve warehouse, improving the utilization rate of the storage capacity of the reserve warehouse, and introducing advanced warehousing management technology. Among these, introduces innovative theories for calculating storage capacity of reserve materials and for warehouse area zoning management, providing theoretical support and practical guidance for enhancing the storage capacity of reserve warehouses. At the same time, research on strengthening reserve and warehousing capabilities has been proposed, be focusing on establishing reserve and warehousing logistics networks, building professional reserve bases, and other directions.
