摘　　要：以塔里木河干流上中游为研究对象,对河道损耗进行了分类分段分析,结果表明:河道渗漏与漫溢是径流损耗的主要构成,平均约占总耗水量的95.77%;研究10%、25%、50%、75%和90%来水频率下,研究区年水面蒸发量、河道渗漏量、河道漫溢量。开展河道损耗定量分析,对于实现区域水资源的合理配置,可提供重要的数据支撑。Taking upper and middle reaches of Tarim river as the research objects, this paper classified and analyzed the channel losses. The results showed that seepage and overflow were the main components of runoff loss, accounting for an average of 95. 77% of total water consumption. This paper studied the annual water surface evaporation, channel leakage and channel overflow in the study area under the water frequency of 10%, 25%, 50%, 75% and 90%, respectively. Quantitative analysis of channel losses could provide important data support for the rational allocation of regional water resources.
