摘　　要：运用非参数检验、Z指数法对塔里木河干流径流序列进行分析。结果表明:塔里木河干流各水文站年径流量均呈减少趋势,其区间耗水量也呈现减弱趋势;塔里木河干流20世纪80年代以平水期为主,20世纪90年代以平水和枯水期为主,2000—2010年以偏枯、极枯年份为主。就径流量年内分配来说,7—9月径流量占全年径流量的70.24%。研究结果对于流域生态环境保护、水资源的可持续利用提供了重要参考。By using non parametric test and Z index, Tarim River trunk stream runoff time series is analyzed. The results show that the Tarim river hydrologic station annual runoff showed a decreasing trend, the range of water consumption showed the weakening trend; In80 s of last century in normal water period, on 90 s to century flat water and dry season, from 2000 to 2010 to dry, very dry years. In terms of annual runoff distribution, runoff from July to September accounted for about 70. 24% of annual runoff. The results provide an important reference for ecological environment protection and sustainable utilization of water resources.
