摘　　要：水稻生产系统是复杂的多因子系统,基于水稻生育指标-环境因子-技术措施关系构建的水稻管理知识模型,初步实现了水稻管理知识表达的模型化和数字化。由于水稻生产管理中存在较多异构数据,现有模型难以克服时空适应性弱及代码重用等不足。本体(Ontology)作为一般化的数据库模式,可用于描述比普通数据库更复杂对象的语义结构,其支持信息共享和代码重用。本研究以水稻为对象,通过本体表示、本体构建和本体集成,拟建立基于本体的水稻管理模型,以实现水稻生长模拟、水肥运筹和病虫防治等功能。Rice production system is a complex system, based on the relationship of crop, environment, and technique, a rice management knowledge model made the management knowledge be presented modally and digitally. Because of isomerous data, the model in existence had shortcomings as adaptability and reusing. Ontology can describe complex object＇s semantic structure, which supports sharing and reusing. In this paper, by representing, developing and integrating Ontology for flee, a management model based on Ontology will be developed, which can integrate the growth simulation, water and fertilizer strategy, and integrated pest management.
