In the research, the definition of production system of integrated agriculture was proposed, and the theoretical basis (system theory, information theory, cybernetics and operational research) and the key technologies were analyzed. Furthermore, IDEFO of production system of integrated agriculture was established and the constituents of different subsystems were analyzed. In addition, the components of the integrated platform, involving operational system, network, distributed database, communication services, information services, development tools, management and application services and platform entrance, were discussed. In agricultural integrated system, relationship among subsystems should be well considered under guidance of system theory in order to better improve controllability and productivity of agricultural activity. 展开更多
