摘要：

The Qilian Mountains is the cradle of allinland rivers in the Hexi arid region.The mountain glaciers are an important water resources for this region.Changes ofthe mountain runoffsresulted fromglobal climatewarming will have important impacts onthe development of human society and economy in the region.In this paper,the river runoffsfrom the Qilian Mountains and theirdynamic changes are analyzed on the basis of the instrumental data of precipitation,air temperature,and discharge from theweather and hydrologicalstations in the studyarea.The results show that the annualchange in the mountain runoffs isaffected mainly by precipitation in the east of the region,but also by temepraturein the west of the region.There are some obvious regional differences in the influence of climatic change onsurface runoffsin the Hexi region.River runoffsin the western part of the Hexi region have beenincreasing,whereas thosein the easternpart have beendecreasing.River runoffsin the central part such as the Heihe River,present a slow increasingtrend,although it isnotquite visible
