土壤适宜性评价过程是涉及多学科多领域,需要借助于多方面经验知识的问题。近年来,在智能信息处理、知识管理工程领域出现的本体是知识表示、共享和重用的崭新方法。本文将本体知识库系统构建应用到土壤适宜性评价领域中,首先,采用基于本体的知识表示方式,着眼于土壤资源对用地适宜性的影响,分析相关的领域知识,构建土壤适宜性评价领域本体知识库。在完整分析系统设计思路及系统结构基础上,结合本体知识库与规则推理技术实现系统的知识推理,完成系统构建。最后,文章给出一个本系统的土壤环境质量评价及适宜性分析的推理实例,并分析推理结果,以此验证系统可行性和实用性。
Soil suitability assessment process is a multidisciplinary and multi-disciplinary field, which requires the help of many aspects of empirical knowledge. In recent years, ontology in the field of intelligent information processing and knowledge management engineering is a brand new method of knowledge representation, sharing and reuse. This paper applies ontology knowledge base system construction to the field of soil suitability assessment. Firstly, using knowledge representation method based on ontology, this paper focuses on the influence of soil resources on land suitability, analyzes related domain knowledge and builds the ontology of soil suitability evaluation knowledge base. Based on the complete analysis of system design and system structure, this paper combines the ontology knowledge base and rules reasoning technology to realize the system’s knowledge reasoning and completes the system construction. Finally, the article gives an inference example of soil environmental quality evaluation and suitability analysis of this system and analyzes the reasoning results to verify the feasibility and practicability of the system.
