摘　　要：计算机网络是地理空间信息网格的载体,二者之间有着密切的联系,其关联性主要表现在互连互通、基于协议、交互接口和虚拟组织几个方面。计算机网络遇到的安全威胁,地理空间信息网格也同样会遇到。此外,地理空间信息网格还要面对自身特征带来的诸如攻击核心设施、导致整体瘫痪,或破坏局部计算等各种安全威胁。针对这些问题,基于用户、通信网络、应用程序和网格资源四个环节,研究设计了地理空间信息网格安全体系结构,并论述了各模块的功能和相互之间的关系,以及整体协同运行程序。The computer network is a carrier of the geographic space information grid, and there is a close connection between them. On the basis of the agreement, the relationship mostly represents in interconnection, mutual connection and dummy organization and so on. geographic space information grid is facing the same security threat as the computer network does. In addition, the geographic space information grid also facs its own characteristic, such as the attacking core installation which causes the whole system to paralyse, or destructing partial computation and other kind of security threat. To solve these questions, based on the user, the correspondence network, the application procedure, and the grid resources, the security system structure of the geographic space information grid is researched and designed, various modules function and ther relations are expounded and the whole coordinative operation procedure is given in this paper.
