利用乌鲁木齐河1957－2009年的径流、气温、降水逐月资料，分析乌鲁木齐河上游出山口年径流变化特征及其与气候变化的关系。研究结果表明：①乌鲁木齐河上游出山口径流的年际变化相对稳定，但年内分配极不平衡，其中夏季径流量最大，约占全年的61.8％，其他各月径流量只占全年的38.2％；从汛期和枯期来看，乌鲁木齐河上游汛期和枯水期径流量相差较大；②近50年来，随着乌鲁木齐河上游流域出现明显的升温趋势，流域内降水呈减少的趋势；从径流年际变化的分析来看，随着乌鲁木齐河上游流域来水的增加，降水和气温的变化显著。

Use the monthly average runoff , temperature and precipitation data from the upper reach of Urumqi river basin during 1957-2009 , the characteristics and reasons of the upper reach runoff change in Urumqi River basin in the recent 50 years were analyzed.Results showed that:①The an-nual variability of the upper reach runoff of Urumqi river is relatively stable.However , unbalanced distribution of seasonal runoff is distinct within a years; the runoff mainly concentrated on summer (June, July, August) and accounts for 61.8% of the annual runoff while the accumulative propor-tion of other three seasons account only for 38.2%.In terms of the flood season and dry period , the runoff between them usually has large fluctuation;②The temperature from the upper reach of Urumqi River basin has a trend of obvious increase in recent 50 years while precipitation has a trend of de-crease.From the initial analysis of the generation changes of the upper reach of the Urumqi River , we can get with the increase of run off , the precipitation and temperature of this area also changes significantly.
