In this paper,th e annual runoff variation and its climate impact factors were analyzed by using statistical analysis method, Mann-Kendall test method and Morlet wavelet analysis method based on the data of runoff volumes at Meigang hydrological station in Xinjiang basin during the period of 1953-2011. The results show that the annual runoff volumes present slightly increase trend with obvious interannual and interdecadal variation characteristics,especially for the period of 1970-1990.The interannual cycle change is 6-8 years and the interdecadal cycle change is about 22 years. The maximal monthly runoff appeared in the main flood season(April-June). During spring and summer,variation of runoff shows a low coefficient with stable flow quantity while shows the opposite state in winter. Obvious correlation can be found between runoff volumes and climate factors.Moreover,economy,population and human activities in the urbanization played supporting roles in runoff changes.
