| 摘 要： | 介绍了地理专家系统(GES)辅助决策系统的构建原理与实现方法,讨论了GES中专家知识的表示方法与推理控制策略。系统将领域专家知识划分成不同的层次和类型,采用框架网络数据结构和产生式规则表示地理学领域专家的专门性知识与经验性知识,使知识的表示简洁易于理解。在知识的推理策略中引入不精确推理机制,保证了推理机制的实现。以乌鲁木齐河流域为试验区,阐述了流域土地合理利用规划决策专家知识的表示方法,以及专家知识表示的基本规则和系统专家知识的组织方式。

| Abstract: | This paper presents building principle and accomplishing approach of Decision Support System for Geographic Expert System (GES), and discusses the means of expert knowledge expression and inference control strategies in the GES. The field expert knowledge is divided into several grading levels and classifications in the system. And the framenet data structures and productive rules are used to express field knowledge and expirience of geographic expert so that the expression of knowledge is more concise and easy to understand. Meanwhile the indistinct inference mechanism is introduced in the inference tactics of knowledge so that the reasoning mechanism is assuredly realized. Furthermore, taking Urumqi river basin as a test region, the author expounds expression approach of expert knowledge for land rational use design and decision in the watershed ,and probes the basic rules of expert knowledge expression as well as the organization model of expert knowledge in the system. Moreover, the author also discusses the design principle and organization approach of inference rules for inference engine of the system as well as inference algorithms of inference engine. |
