摘　　要：针对传统可用性评估方法中存在的主要问题,提出要设计地学信息可视化系统的可用性辅助评估工具。本文首先分析传统常用的可用性评估方法及其存在的主要不足,提出解决这些问题的基本想法。然后提出地学信息可视化系统可用性辅助评估工具的总体设计思路及系统的工作流程,并详细阐述了系统的功能模块与关键技术实现。该工具可以减少测试过程中的主观影响,节省开支,更加有效地利用有限的样本,提高可用性评估结果的科学性。Usability is a hot research work in recent years. In order to solve the main problems of the traditional usability evaluation, this paper submits a new idea-the tool of usability evaluation for Geo-visualization. In this paper, it introduce the common usability evaluation methods, and analysis the main problems： the strong subjective affect, poor credibility, non- repeatability, high cost, and so on. So it proposes the basic idea to solve those problems. Then it argues the main thought and work procedure of the geo-visualization evaluation tool, and explain the function and the key technology in detail. The tool can reduce the subjective affect, and cut down expenses, and make full use of the limited sample, and enhance the scientificalness of the result for usability evaluation.
