摘要
以垦利县为代表详细介绍了黄河三角洲地区苜蓿生产环境信息数据库的结构、数据分层编码原则及建立过程。该数据库以Arcview和Arc/info为基本工具,采用Arcview管理空间数据,Visual FoxPro管理属性数据,二者通过公共字段共享数据,实现了属性数据与空间数据的无缝链接。该数据库对区域内生态开发中的资源管理、评价与规划及动态监测具有重要的实践意义。
Production environment database of alfalfa in Yellow River delta（a case study on Kenli county）was established. The structure of database, rules of data coding and processing of establishment were introduced detailedly in this paper. The database was established by using Arcview Gis and Arc/info as the main technologies, managing spatial database by Arcview Gis and managing attribute database by Visual Foxpro through common field.
