摘　　要：针对水稻病虫害的特点与特征,集成数据库技术、多媒体技术和地理信息技术开发了水稻病虫害咨询与诊断系统。本系统共收集了150多种水稻病虫害,集查询、诊断、预测和防治多种功能于一体。系统采用专家数据库进行知识的表达,结合了一种新的推理方法对水稻病虫害诊断的知识进行有效组织,有效地解决了病虫害诊断过程中知识的不确定性。On the basis of the character and feature interpretation of rice pest insects and diseases, an system for management and diagnosis of dee pest insects and diseases was developed which synthesized the database technology and multimedia technology and geographic information technology.The system collected more than 150 kinds of rice pest insects and diseases and offered many functions, such as data query, diagnosis and forecast. For the knowledge expressing, we gave a kind of description way using expert database. For the inference engines, we applied a new method to deal with the uncerrain knowledge of rice pest insects and diseases diagnosis.
