In order to further solve the problems existing in the process of land resource management of relevant departments of land and resource management, realize the information management of land resources, and promote the efficient utilization of land resources and scientific information management, this paper proposes a land resource management system based on Internet of things technology. With the help of resource allocation and management algorithm based on the needs of Internet of things users and land resource management requirements, this paper constructs a land resource management system based on Web and mobile network platform. The system development takes Java as the background programming language, constructs the database based on Oracle 9i, and uses GIS/GPS and other electronic map functions to realize the accurate display and resource sharing of land resource information. In the system test, 60, 120, 240, and 360 concurrent users are simulated to access the system at the same time. The connection success rates of the corresponding system are 97.2%, 97.5%, 98.3%, and 96.6%, respectively, which fully verifies the good performance of the system; it can be widely used in land resource information management.
