摘　　要：西藏自治区是我国面积最大的省区之一,也是我国河流、湖泊、冰川分布最广的区域。由于地域辽阔,加上地势、纬度的影响,西藏地区水文气象要素差异性很大。西藏大部分地区水文站网密度偏低,水文资料较匮乏,有些地区基本空白,属无资料地区,给工程水文设计带来很大的困难,包括设计洪水计算。为此,以藏东南察隅县吉太曲流域为例,研究探讨无资料地区设计洪水分析计算方法。Tibet is one of the largest provinces in China and also is the most widely distributed area with rivers, lakes and glaciers. Due to the large scale in width and terrain, Tibet has lots of differences on hydrological and meteorological elements in different area. As the hydrological station is rare and the network density is very low in most area of Tibet, the data of measured discharge is shortage （ such area is often called ungauged basin）, which is the biggest challenge when calculating the design flood. Taking Jitai River as an example, the design flood is calculated by using three methods and then the results are discussed.
