- Abstract:

We analyzed the interannual and inter-monthly runoff characteristics of Hongshanzui hydrologic station of Manas River by using R/S, Morlet wavelet, Mann-Kendall nonparametric test and concentration and concentrated period methods based on the Hongshanzui hydrologic runoff data in the past 60 years. Results show that in the past 60 years, interannual change of runoff of Hongshanzui hydrologic station was not significant, and had long-term upward trend, runoff series had strong long-term sustainability; annual runoff presented 14 to 35 years, 6 to 13 years and 3 to 5 years periods, and the first main cycle is 21 years, and then 28 years, the third was 13 years; runoff cycle changed frequently before 1980, but the change was small, and the cycle became longer and lager after 1980; the order of the rich and low water period was flat, rich and dry; the runoff abrupt occurred in 1994. The monthly runoff followed uneven distribution and high intensity, and the runoff mainly concentrated in the end of July; Runoff showed a significant rise, most of the runoff abrupt occurred after 1990.
