【摘要】 针对我国农村科技人员和农民知识水平低，园艺设施工程建造的盲目性大、投资效益低的问题，国家教育部择重列项，题为“工厂化高效农业智能信息系统与技术的研究”。于与应对，本文则重点应用计算机技术和专家系统理论，在归纳总结设施园艺和设施工程专家的经验知识和园艺资料的基础上，研究开发了适合山西省及周边地区运用的园艺设施工程技术专家系统。 本研究运用工程—生物—经济一体化的理论，解决了系统设计中变量因子多而杂、且相互耦合研究少的难题；运用分层策略，解决了园艺设施类型多、标准化程度低、数量大小参差不齐的难题；在决策分系统中，利用加权的不确定推理，解决了因规则的不确定性而带来得推理机制的难题。 园艺设施工程技术专家系统的开发以Windows95／98操作系统作为开发平台，采用Visual Basic6.0语言和面向对象技术进行设计。通过分析用户对园艺设施概况信息和建造决策的需求，本专家系统由园艺设施概况咨询和园艺设施建造决策两个分系统构成。运用可视化技术、人机交互方式设计的系统界面友好，操作简单方便。 经文献检索，国内尚未有研究开发园艺设施工程推广技术专家系统的报道，因此，本系统的设计与开发具有实际的意义与应用价值。当然，由于该系统研究工作量大、时间仓促，还有待于进一步改进和完善。更多还原

【Abstract】 Aiming at rural technical personnel and farms knowledge lacking, protected horticultural engineering construction being unreasonable, the investment efficiency rate of the engineering low, National Ministry of Education establishes the important project, The Research of Intellectual Information System and Technology on Industrialized Agriculture, to overcome them. It is in this paper that the expert system on the engineering of protected horticulture, which is available in Shanxi province and adjacent area, is developed on the basis of summarizing knowledge, experience and data accumulated by experts in protected horticulture and protected horticultural engineering, mainly with computer technology and expert system theory.It is this research that overcomes the difficult problems which variable factors in system design are many and researches about their coupling property are few with using engineering-organism-economy united theory, which horticulture facility types are too many, standardization low and dimension diverse with delamination strategy, and which reasoning in decision -making subsystem is hard because rules are uncertain with using uncertain reasoning with weight.It is windows 95/98 that is taken as its develop platform. It is adopted for the programming that is the language of Visual Basic 6.0 and the method of Object-Oriented design. Through analyzing the requirements of users for protected horticultural information and protected horticulture construction decision-making, the expert system is composed of protected horticultural information counseling subsystem and protected horticulture construction decision-making subsystem. User interfaces are made up with visual design in friendly interfaces and conveniently operations.According to literature index, no report on research of expert system in the engineering of protected horticulture is found so far in our country. Therefore, the design and development on this system has practical meaning and appliance value. However the expert system is going to need to be advanced and perfected for the research capacity abundant and time inadequate.更多还原
