摘要
在通过开发基于专家知识农用地定级专家信息系统实践的基础上,探讨了ES与GIS集成技术运用于农用地定级的优越性。同时提出了系统设计的原则和性能要求,对系统总体结构、数据库结构、主要功能模块和菜单等进行了设计分析。
Based on the practice of developing a farmland grading information system through using the coefficient revising method, this paper discusses the superiority of applying integrated technology of GIS and ES to farmland grading. Meanwhile, the paper presents the principle and capability of the system design,analyzing the collective frame,the structure of database,the main modules and main menus of the system.
