Abstract: This paper proposes a visualization method of community based on the theme of the community.It analyses the community and its characteristics at first.Then it proposes the visualization method in order let the users grip the architecture of the network.It also visualizes the link to make users get the relationship between communities and realizes the method based on OpenGL，and visualizes the number of a paper-searching network.The users can get the process of different themes’ research clearly from the visualization.This method can also be used to visualize the Internet navigation.By this，users can know where they are in time when searching on line.

Key words: network community, visualization, community architecture, network navigation

摘要： 针对网络社区的主题特点，提出一种网络社区可视化方法。首先分析网络社区及其特点，然后提出一种网络社区可视化方法，通过该网络社区可视化方法，用户能够更加清晰掌握网络层次组织结构。对社区之间的链接进行可视化，使用户能够直观获得社区的联系。并且基于OpenGL实现了网络社区可视化方法，对某论文搜索网的文档数目进行可视化，从可视化效果看，用户能够清晰得到论文不同主题的发展动态。该可视化方法可以运用于可视化导航，使用户实时掌握所处的社区主题。
