Runoff evolution pattern research is the premise of the rational use of water resources and water resources planning. Bayingou River is a typical mountain stream river in Xinjiang. According to the time series data of annual runoff at the Heishantou hydrological station of the Bayingou River from 1956 to 2014, we used accumulated anomaly, Mann-Kendall test and wavelet analysis to diagnose the runoff change trend, mutation characteristics and cycle evolution pattern. The results showed as follows. (1) Annual runoff was slowly rising trend. (2) In recent 60 years, annual runoff mutations happened in 1958—1960 and 2003. From 1958—1960 to 2003, the runoff kept sloping down, but began to climb up since 2003. (3) The principal periods of annual runoff of the Bayingou River were 7 years, 11 years and 30 years, and the 30 years period is the most obvious.
