摘　　要：对当前地理空间数据存储管理的现状进行分析 ,指出当前地理空间数据存储管理中存在的主要问题 ,简单论述了如何利用 SAN和 HSM技术来构建地理空间数据分级存储管理系统 ,以解决当前地理数据中心面临的存储管理问题。This paper first analyzed the status of data saving and managing on Geographic data,and put forward some problems in our current data saving and managing procedure. Then described on how to solve those problems by building a hierarchical storage management system using Storage Area Management (SAN) technology and Hierarchical Storage Management (HSM) technology. HSM system described in this paper would administer to satisfying the needs of safely and automatically managing geographic data and would lighten the pressure of most geomatics centers, also would be significant to more efficient management and application service on geographic data.
