| 摘 要： | 在多年水文数据的基础上,分析了塔里木河中游1957~2002年间径流年际变化及1992~2002年径流月际变化的特点、趋势及其原因和影响。得出1957~2002年间塔里木河中游径流不稳定、不平衡,并且径流呈逐渐减小的趋势,其主要原因是源流区和上游区大量引水所致;塔里木河径流月际变化呈明显的西北型河流的特点,在7~9月为洪水期,水量可占全年水量的79.31%,4~6月份由于农业用水,导致径流量下降。塔里木河径流的这些特点给水资源管理加大了难度。

| Abstract: | According to hydrological data of many years,the runoff of the middle reaches of the Tarim River is analysed,including the characteristic,trend,reason and influence of runoff change which involves the annual runoff from 1957 to 2002 and the average monthly runoff from 1992 to 2002.The runoff of middle reaches of the Tarim River is unstable,uneven,and takes on a gradually reduced tendency.The reason is that a large amount of water is abused in the source rivers area and upper reaches area.The monthly runoff of the middle reaches of the Tarim River shows obvious the northwest river's feature.From July to September,the quantity of the water takes up 79.31% of whole year.Owing to agricultural irrigation,the runoff is descended from April to June.These features of runoff bring a lot of difficulties for the administration of water resources in the Tarim River. |
