Research and development of a land resource management information system based on the multi-dimensional information fusion is studied in the manuscript. Information fusion as a multi-layered, multi-faceted, and multi-level process that involves the detection, correlation, combination, and estimation of data from multiple sources. In this study, the fusion model is integrated to make the land resource management information system efficient. Information resource management needs not only hard information technology as a theoretical support, but also soft management methods as a means. The application is defined and studied for improving the efficiency.
