重庆市土壤信息系统设计

Designation of Chongqing Soil Information System

用计算机技术管理土壤信息是智能化农业信息技术的重要环节。在地理信息系统的框架内 ,探讨了土壤信息系统的开发思想与开发方法。以三层体系结构形式构建了重庆市土壤信息系统 ,为农业专家系统提供支撑条件。采用面向目标的设计方法和逐步揭示技术设计了简洁明快的用户界面 ,可方便的提取土壤的一系列相关数据。其模块化结构便于维护、更新和扩充。系统可直接为农业生产服务。

It is a key link that agricultural information technology uses computer technique for managing soil information. The paper discusses some questions for soil information system in theory and method. Chongqing soil information system (CQSIS) is constructed by three tiers system structure and afforded a support of condition for the expert system. An effective interface is designed for the system by the method of “goal-orienting” and “Gradual exposition” technique. It is convenient to pick up a series of data. The blocking construction can be maintained, updated and expanded easily. The system may serve the agricultural development by the convenient software operation.
