Abstract: Agent technology is applied into constructing distributed GIS. Firstly, the classification and structure of agent in distributed GIS are analyzed; then the model of distributed GIS-oriented multi-agent system named as Geo-Agents is designed and implemented, including its communication mode, architecture and distributed mode; at last, the uses of Geo-Agents are explored: agent-based spatial information navigation and spatial decision-support system.

Key words: Agent, distributed GIS, Geo-agents, spatial metadata, spatial decision-support system

摘要： 将Agent技术应用到分布式GIS的建设中来，分析了分布式GIS中Agent的分类与结构，设计和实现了一个面向分布式GIS的多Agent系统模型Geo-Agents, 给出了其通讯模型、体系结构和分布模型，并探讨了它的应用：空间信息导航和空间决策支持系统。
