摘　　要：为了分析雅鲁藏布江干流的年径流变化趋势,采用趋势分析和小波分析的方法,基于雅鲁藏布江干流羊村和奴下水文站1970~2012径流序列资料,对其干流径流的变化趋势和特性进行分析。结果表明,干流径流呈现一定的增长趋势,但趋势不显著,同时不存在显著的跳跃成分。雅鲁藏布江有较丰富的水资源可供利用,且水量来源较为稳定,受气候变化影响不显著,可为南水北调的大西线调水工程提供水源保障。Yarlung Tsangpo River is rich in water resources and hydropower resources,which is important to the development of Tibet and the South-to-North Water Division Project. The trend analysis and wavelet analysis were used to study the characteristics and variation of annual runoff of the river on the basis of the annual runoff series data of Yangcun and Nuxia Hydrological Station from 1970 to 2012. The results showed that the annual runoff is increasing,but the trend is not significant; no abrupt point exists in the annual runoff series. The research indicated that the water resources of Yarlung Tsangpo River is rich,and the incoming flow is stable and not obviously influenced by climate change,which could be used for the Western Route Project of South-to-North Water Division Project.
