Seismological science data visualization become more and more importance. The paper firstly briefly introduces the basic situation of seismological science data and the level of their visualization, and then, using the seismic deformation data as an example, introduces the overall framework and technical route of seismic ground deformation data Quasi-realtime visualization system, analysis of the specific implementation process of drawing display and data acquisition module in the system, in order to emphases the system's research focus and difficulties.%地震科学数据的可视化需求越来越受到重视。首先简单介绍了地震科学数据的基本情况和可视化层面的研究现状，然后以地震地形变数据为例，详细阐述了地震地形变数据准实时可视化系统的总体架构和技术路线，分析了系统绘图展示和数据获取模块的具体实现流程，以突出数据可视化系统的研究重点和难点。
