园艺植物专家系统研究概况与发展趋势

Research Status and Development Tendency of Horticultural Plant Expert System

介绍了国内外专家系统在园艺植物方面的应用,提出了其发展过程中仍存在的问题,如知识获取的"瓶颈"问题、园艺植物专家系统性能较差、未形成成熟的园艺植物病虫害诊断知识的知识模型、未能从诊断推理思维方式出发建立园艺植物病虫害诊断知识的推理求解模型、缺乏系统应用效果的反馈、专家系统的商业性较差和农业专家系统的开发平台需要进一步研发等。展望了农业专家系统的发展趋势:利用"3S"、模型模拟、智能决策、多媒体技术等多技术的集成开发园艺植物专家系统;开发综合性农业专家系统;注重实用性,开发不同用户群体、不同层面的专家系统;利用图像识别检索等人工智能手段进行病虫害诊断。

The paper introduces the application of horticultural plant expert system both at home and abroad, proposes the problems existing in its development, such as the ＂bottleneck＂ problem of knowledge acquisition,the poor performance of ES,immature knowledge model of diagnosis in diseases and pests,reasoning knowledge model of diagnosis in diseases and pests can＇ t be built from the way of diagnosis reasoning mode of thinking, a lack of feedback of practical effect in using ES, the poor commercial performance of ES, a need of further research on agricultural ES development platform. Finally the paper forecasts the development tendency of agricultural expert system： developing horticultural plant expert sys- tem based on the integrated technology of＂3S＂ ,model simulation ,intelligent decision ,multimedia technique intelligent ,etc. ; developing compre- hensive ES and exploiting ES of different levels for different users ;using artificial intelligence tools such as the way of image recognition search to diagnose 13ests and diseases.
