Based on Arcgis Server, spatial metadata and spatial database engine, a precision management system for citrus cultivation at four different levels involving municipality, county, township and key demonstration zone is designed. The system consists of user management, data management, inquiring and analyzing, special drawing and model management. It has many functions such a the spatial query for citrus distribution, disease diagnose, planting suitability evaluation and yield prediction, and provides the technical support and the auxiliary decision-making for the productive layout and scientific management of the current Citrus.
