Abstract: Without strong data supportance, digital agriculture cant be fully employed. To solve current problem of “information isolated island” in agriculture resource management of Jiang jin Chongqing, an agricultural resource information shared system that integrates 3S, Web technologies, database and other technologies was developed. The system adopts the model of combing centralized metadata & physical database and centralized metadata database & distributed physical database, providing the services of data management, data retrieval and query as well as data publishing. Application result shows that the system can take fully advantage of available agricultural resources data to provide supportance for agriculture yielding decision-making; also can reduce costs greatly in agricultural resources information gathering and processing, contributing to agricultural resource digitized and standardized development. Meanwhile the methodology that targets for agricultural resources management and sharing also applies for other fields, which to certain degree hence is of promotion significance.
