时序数据广泛存在于各种科学领域尤其是天文科学研究之中，信息可视化是对数据进行分析的有力工具，然而现有的可视化技术却无法较好地分析具有大规模数据量且时间跨度长的天文时序数据。合并树提供了一种新的对于天文时序数据可视化分析的手段，能够在快速显示数据整体信息的情况下同时查看细节信息。实例分析充分验证了该方法的有效性和易用性，它为大规模的天文数据分析提供了有效的工具。

Time series data is widely existed in scientific research especially in astronomy, current visualization technique cannot efifciently analyze astronomic time series data with very large scale of data and time span. Merger tree provides a new method for astronomic time series data analysis, which can both display overall information of data quickly and check the details in the meantime. Example analysis veriifes that the method is efifcient and esay to use, and offers an effective way for astronomy data analysis with great data scale.
