摘  要:
针对当前农用地定级系统的计算过程复杂、通用性较差等问题,该文对农用地定级过程中涉及的自然、社会经济等多方面的图件和属性数据进行了分析,并对农用地定级相关模型进行了分析和归纳;在此基础上,采用地理信息系统技术,结合专家系统和决策支持系统理论,重点设计了系统空间数据库、知识库、模型库和推理机。在VS2005集成开发环境下,采用C#语言,结合ArcGIS Engine组件技术,研制开发出了农用地定级决策支持系统。系统实现了农用地定级的可视化、自动化和智能化,能较好地解决农用地定级中半结构和非结构化问题,具有较好的通用性和可推广性。

摘  要:
Complex calculation process and poor generality are difficult problems in present farmland grading system. This paper analyzes the natural and socio-economic graph and attribute data involved in farmland grading process,and summarizes the relative farmland grading models.on this basis,the spatial database,knowledge base,model base and inference engine of the system were designed combining with the theories on expert system and decision support system. A farmland grading decision support system was developed using C#programming language and ArcGIS Engine component technology in VS 2005 integrated developing environment.This system realized visualization,automation and intelligence of farmland grading,and solved half-structured and unstructured problems in the process,with better generality and promotion.
