| 摘 要： | 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。

| Abstract: | Soil suitability evaluation is a complex issue which concerns many disciplines and depends on varied knowledge and experiences.In resent years,the ontology coming from fields of Intelligent Information Processing and Knowledge Management Engineering is a new method for knowledge representation,sharing and reusing.In this paper,the ontology-based knowledge representation and the technique of ontology-based knowledge base system（KBS） were applied in the soil suitability evaluation domain.Firstly,the necessity and innovation of using the ontology-based KBS in the process of soil suitability evaluation was discussed.According to the system target of soil suitability evaluation application,the framework of ontology-based KBS and the key technologies to implement it were prompted.By combining the essential connotation and general process of soil suitability evaluation,the system design ideas of ontology-based KBS used in soil suitability evaluation domain was determined,and the system architecture using OWL and Jena2 was presented.Based on analysis of soil suitability evaluation and associated fields such as crop cultivation and land use,the core concept set and relevant set of domain ontology model were extracted,and the soil suitability evaluation ontology was developed by OWL,the domain ontology language.Based on the extracting of reasoning rules for soil suitability evaluation and soil property knowledge representation,the reasoning rules of the system was put forward according to the rule syntax of Jena2.Then the ontology and rules was stored in the ontology-based knowledge base（KB） by using the system functions of persistence storage and rule editor.Base on the construction of ontology-based KB and rule-based reasoning mechanism,the KBS fruit planting suitability evaluation was carried out by developing and integrating of the system functions for ontology parsing,ontology instances constructing,rule-based reasoning and result querying.Finally,we present an example of soil environmental quality and soil suitability analysis to prove the feasibility and practicability of the system.The research shows that the ontology-based knowledge based system can make effective use in the process of soil suitability evaluation and increase knowledge sharing and reusing. |
