土地资源信息系统数据库的设计研究——以乾县试区为例

The designing of land resources monitoring information system database——A case study of Qianxian County experiment area

建立土地资源信息系统可以为合理开发土地资源提供信息来源与最佳方案,而数据库的设计是建立土地资源信息系统最关键部分。以乾县试区为例,应用Visual FoxPro与ARC/INFO建立基于Windows平台的黄土高原区土地资源信息系统数据库,并在此基础上设计了数据库管理系统,为建立水土流失严重、生态环境脆弱区的土地资源信息系统奠定基础。

Building the land resources information system will provide information resource and the best project for reasonable exploitation land resources, and the design of database is the most important component in land resource information system. This paper, taking Qianxian County experimental area as a case study, establishes the database for land resource information system by using visual FoxPro and ARC/Infor. This paper also designs data management sytsem. These results establish the basis for land resource information system at severe soil loss region.
