In order to promote the orderly development of cities and realize social public interests, a design method of a land reserve-oriented multimedia information management system is proposed. It is of great practical significance to integrate and sort out the whole process of land reserve projects through spatial information platform, effectively manage land reserve, land supply, and planning information, improve the utilization rate of land resources, and provide information support and decision-making basis for land expropriation and land registration and certification. By combining scattered information resources, integrated into a unified information service platform, realize the unified update and maintenance of all kinds of data, increase the reusability of data, and avoid data synchronization between the two levels of urban land reserve departments and the resulting waste of resources. After three tests and modifications on 50 devices, successfully increased the operation success rate from 86% to 100%, and a complete and effective land reserve multimedia information management system has been successfully developed. In order to better do the handover and transition of the reserve work, it is necessary to integrate, update, and improve the historical and existing reserve projects and build a unified and standardized land reserve geographic information database, so as to effectively promote the sharing and application of information resources.
