摘　　要：网格技术与数据可视化科学的结合探索是跨领域研究的难点与热点.本文提出了分布式、合作的、支持异构资源的自动获取和分配的网格可视化环境GVFrame.GVFrame为地理分布的合作用户提供可视化资源共享的框架,该框架以基于OGSA规范的Gridweb Services作为运行背景,使用可视化资源代理(Vis Broker)简化远程资源的分配和使用.GVFrame核心资源层VS(Visualization Grid Services)基于分布式可视化流程映射模型,将可视化组件合理分割并分布到网格环境中,并利用数据服务驱动机制处理合作用户的数据更新和渲染流水线.The combined exploration of grid technology and science of data visualization is a new paradigm in cross-domain science research.GVFrame presented in the paper is a distributed and collaborative web-service-based visualization environment that we developed to support automated availability and allocation of heterogeneous visualization resources.It provides a flexible framework for sharing of visualization components by geologically distributed collaborative users.The framework based on grid/web services specified by OGSA model uses Visualization resources Broker（VisBroker） for the availability and allocation of remote components.Visualization Services（VS） runs as the core layer of GVFrame which splits and distributes visualization components on the grid following distributed visualization pipeline mapping model.Data driven mechanism is used for updating data and pipeline of collaborative users.
