摘　　要：地图是最直观、最有效的空间信息可视化载体.文中从地理信息系统(GIS)空间查询与空间分析的角度探讨了地图可视化中人机交互的过程,分析了可视化交互界面的主要功能,阐述了交互式可视化查询的3种方式及其与交互界面的关系,给出了一个交互式的可视化空间分析框架,描述了选择、操作、探索和确认这4种基本的GIS空间分析功能模型在空间分析框架中的关系,最后设计并实现了一个基于地图的交互式可视化原型系统,并通过实例验证了系统的实用性.A map is the most intuitionistic and effective visual carrier of spatial information.From the viewpoints of spatial query and spatial analysis of geographical information system（GIS）,this paper discusses the human-machine interaction process of cartographic visualization,analyzes the main functions of the interactive visualization interface,illustrates three modes of interactive visualization query and the relationships between the modes and the interface,presents a framework for the spatial analysis of interactive visualization system,and describes the relationship among four basic functions of spatial analysis in the spatial analyzing framework,such as the selection,the manipulation,the exploration and the confirmation.Moreover,a prototype system of map-based interactive visua-lization is designed and implemented,the case study illustrating the practicability of the system.
