摘　　要：【目的】建立一种模糊本体的玉米病害知识表示及推理模型.【方法】将利用数据源得到的数据构建模糊本体,结合模糊理论,利用本体技术构建病害诊断模型.【结果和结论】该模型给合本体的形式化定义和模糊理论的不确定表示的优势,将模糊理论引入到本体构建中,突破了本体只能表示确定知识的局限性.将该方法用于玉米病害诊治中,对农业生产中病害诊治起到了很好的指导作用.[Objective] To construct a fuzzy ontology of maize disease knowledge representation and rea-soning model .[Method]Using data from sources to construct fuzzy ontologies ,which were combined with fuzzy theory to construct the disease diagnosis model by ontology technology .[Result and conclusion]The theory of fuzzy was introduced into the description of ontology form and the shortcoming of an ontology re-presenting the narrow defined knowledge only was overcame by this model .Combining the formal defini-tion of ontology with the indeterminacy presentation advantage of the theory of fuzzy , the robustness of maize expert system for diagnosis and treatment of diseases was increased .Meanwhile , this model im-proved the accuracy of diagnosis and treatment of maize diseases and presented a new knowledge repre -sentation reference for other agricultural production expert systems .
