Study on Growth Model-Based Decision Support System for Rice-Wheat Rotation Production

In order to develop a growth model-based decision support system for rice-wheat rotation production adapting to different temporal and spatial environments,Firstly,a rice-wheat rotation growth simulation model with strong mechanism and forecasting characteristics was developed by using system analysis theory and mathematics modeling method,in this study.Secondly, a growth model-based integrated decision support system for rice-wheat rotation production(GMDSSRWP) was developed based on the rice-wheat rotation growth simulation model,weather generation model,and strategy evaluation model,on the platform of Visual C#.net by using the technologies of object-oriented programming and software component.With the effective coupling of the growth prediction,decision-making and alternating technology,the system realized the functions as field information management,expert knowledge consultation,dynamic growth simulation for wheat and rice,strategy evaluation,real-time forecasting,and system maintenance.The system also provides aids for decision-making on rice-wheat rotation farming management and strategy design.
