基于区域生态型的农作物病虫害模型预报运行管理平台的设计与实现OA

To improve the effectiveness and accuracy of disease and pest monitoring and forecasting,and to solve the problem of poor spatio-temporal adaptability of prediction models,a model forecasting system for crop diseases based on regional ecotype was designed and implemen-ted.The system adopts open architecture products(OAP)design concept and client/server(C/S)development approach,integrated with pre-diction models.Its data sources are mainly field microclimate and disease and pest surveillance data.The system includes a four-layer software framework:acquisition layer,data layer,model layer,and publishing layer.It has functions for dynamic modeling,personalized customization,data management,model prediction,forecast release,decision-making assistance,etc.Taking the prediction model of seeding blasts in Dazhu County,Sichuan Province as the demonstration object,the system functions were tested and trial-operated.The results showed that the system can achieve a high degree of personalized modeling or model revision,and the prediction conclusions are in line with the model expectations,which verifies the reliability of the method in this study.
