【Abstract】 This paper describes the design, the structure and the basic functions of DRESS, the Double-cropping Rice Ecosystem-management Support System. It is a two-layer structure system that consists of four professional control system (PCS) and an integral control system (ICS). The ICS is the general platform of the four PCS: technical information system, environmental information system, economical evaluated information system and a rice growth simulation model. The first three PCS represent the knowledge-base of crop management actions, the data-base of environment variables, and the empirical economic model base of various rice-based multiple-cropping system, respectively. The last PCS, the rice simulation model, is the Rice Calendar Model (RICAM 1.3). The basic functions of DRESS are: information mining, simulation, analysis, forecast of rice yield-related processes, determination of the optimum environment-dependent management actions, assessment of the adaptation of cultivars in new planting areas, prediction of flowering dates of parents in hybrid-rice seed production, evaluation of ideotypes in rice breeding, and input-output economic analysis. Options for further improvement of DRESS are suggested.更多还原
