摘要: 针对目前世界上和我国土壤数据库系统研究集中于国家级和区域级地域,多采用小比例尺,宏观性强,但实用性较差的现状,开发基于GIS、ES的大中比例尺土壤数据库系统,利用GIS对图形数据强大的管理和分析功能、ES基于模型和知识的推理功能,结合关系型数据库对属性数据的管理功能,采用实体-联系(E-R)模型设计了实用性强、用户广、直接面向基层和农户、操作简便的土壤数据库系统,并应用GIS软件MapInfo以及二次开发语言MapBasic、ES开发工具DET1.1和Visual Foxpro、Visual Basic进行程序开发

Abstract: In allusion to the actuality of the research of soil database system in both the world and our country, which fastened on country and area, adopted small scale, and was better of macroscopic and worse of practicability, the paper exploits the large and middling scale soil database system based on GIS and ES. Applying on the function of GIS which is good at management and analysis and ES which is better of reasoning based on model and knowledge, combining the function of relation database which is good at administering the property data, adopting E-R Model, it designed the soil database which is practical, has a number of users, is directly qeared to peasants and easy to operate. In the end it adopts GIS software MapInfo MapBasic ES software DET1.1 and Visual Foxpro Visual Basic to programming.

Key words: SOIL DATABASE SYSTEM, GEOGRAPHIC INFORMATION SYSTEM (GIS), EXPERT SYSTEM, E-R MODEL, KNOWLEDGE BASE
