In this paper, based on observations in 26 meteorological stations and 8 hydrological stations of the Tarim River Basin, the changes of temperature, precipitation, runoff, and the relationship between them were analyzed from 1961 to 2005.The results showed that annual mean temperature, precipitation increased by time trend in the Tarim River Basin. After year of 2000, average temperature increased 0.75℃ with an increase rate of 7.69% compared to the long-term average value, in which a increase was larger than in plain area than mountainous area; precipitation increased 16.65mm with an increase rate of 17.89%, in which the increase was more in the mountainous area than plain area; from 1961 to 2008 in Tarim River Basin, river runoff decreased year by year. After year of 2000, compared to long-term average runoff, the average runoff of the Alar station reduced by 1.35×108m3 with the decrease rate of 3%; runoff of Yarkent river Yuzminleke station increased 1.91×108m3 with an increase rate of 21.80%; and the runoff of Hotan river Tongguzleke station runoff increased 1.76×108m3 with an increase rate of 7.88%; the runoff of Wuluwati station increased 1.75×108 m3 with an increase rate of 8.06%; the runoff of Kaikong River Huangshuiguo Station increases 0.58×108m3 with an increase rate of 19.48%; the runoff of the Dashankou station increased 5.43×108 m3 with an increase of 14.33%. Through the analysis on annual average runoff and annual average temperature in the Kaikong of river and Yarkent River before and after 1980s, it could be seen that the effects of average precipitation, climate change temperature on runoff was significant; especially the effect was very remarkable in the river basin origining from the Tarim North Kunlun mountainous.
