摘　　要：分布式应用有着可扩展性、可配置性、灵活可靠性及跨平台等优点。在设计CNGIS（通信网络地理信息系统）的实践中，系统的分布式需求日益突出。该文提出了CNGIS的分布式解决方案，针对不同的应用提出了相应的设计原则及策略，较好地解决了CNGIS设计中的用户分布，特别是数据分布的问题。The application based on distributed structure has the assets of expansibility, configurability, flexibility, reliability and multi-platform etc. In practice, people find that CNGIS essentially requires to be designed as a distributed structure. This paper mainly deals with some design principals and implementation-techniques of the distributed CNGIS. The distributed CNGIS is an efficacious method to share the magnanimity special data and attribute data. With the distributed design, CNGIS solves the problem of user-distributed, especially data-distributed.
