摘　　要：从空间数据服务应用需求出发,分析了几种典型高性能存储系统的特点;分析研究了空间数据服务器系统的数据服务过程,提出并设计了由目录服务系统、磁盘服务系统、数据分布系统、客户应用系统以及高速宽带网络组成的分布并行的空间数据服务器系统体系结构。最后,通过空间数据服务实验,验证了该体系结构的可行性。From appliance demand of spatial data serving, this paper analyzed some characteristics about several representative high-performance storage systems, studied the data serving process of the spatial data server system, put forward and designed a spatial data server system building of directory server system, disk server system, data distrib- uting system, client application system and high-speed wide band based-on distributed parallel architecture. Lastly, it is made sure that the architecture is feasibility by data serving experiment.
