基于知识模型的作物适应性评价专家系统设计

Design of Crop Adaptability Evaluation Expert System Based on Knowledge Model

系统引入了知识模型概念,建立了以知识模型为特征的知识系统,将知识工程、数据库有机结合,采用正向与反向相结合的推理控制策略,建立了基于知识模型的作物适应性评价专家系统,实现了作物适应性评价的计算机辅助决策,具有较强的跟踪解释能力。用本系统对江苏省地区小麦适应性还进行了实例分析。

The system has introduced the concept of knowledge model, and knowledge model system has been set up. On the basis of the knowledge model and positive and negative reasoning control strategy, integrating the knowledge engineering and database developed an expert system on crop adaptability evaluation. The computer aid decision of crops adaptability has been realized and following explaining was adopted in this system. An application example of wheat adaptability in Jiangsu was provided.
