摘　　要：论述关系型数据库存的层次结构和对偶结构,认为在传统的GIS系统中,空间及属性数据的管理应用模式在大规模、多层次的项目数据管理中的采集、管理、应用等脱节,数据的更新和维护困难。为此,在开发自然保护区信息管理系统时,建立了基于关系型数据库的地理数据模型。并对其构成、地理数据与属性数据的逻辑组织、一体化作了论述。The paper elaborates the layer and dual structure of relation-typed database, which regards that the mode of spatial and attribute data in traditional GIS is disjointed of data＇ s collecting, managing and applying in the large scale and multi-layer project data management, and still more difficult to regenerate and maintain the data. Therefore, geographic data model based on relation typed database is established in developing information administrative system of nature reserves. Furthermore, its composing and logical organization and integration of geographic data and attribute data are discussed in the paper.
