摘　　要：对地理实体数据模型、编码方案、组织重构等方面进行研究,提出了构建面向地理实体的基础地理信息库,建立以地理实体为索引的包含多时态、多尺度、多类别的基础地理信息数据库,通过面向地理实体的数据库自驱动更新技术,从技术上辅助实现基础地理信息数据多时态地理实体检索和更新,从根本上解决数据库重复更新、现势性不一致等问题。Based on the study of geographic entity data model,coding scheme and organization reconstruction,this paper proposes to construct the basic geographic information database for geographic entities,a geo-information database including multi-temporal,multi-scale and multi-category is established,through the geographic entity oriented database self-driven updating technology,which can be used for multi-temporal geo-information data retrieval and self-driven updating.Finally,the problems of repeated database update and inconsistent data situation will be fundamentally solved.

关 键 词：地理实体 地理信息数据库 多时态地理实体检索 自驱动更新
