| Abstract: | Based on the data of hydrological station and surface meteorological station of Manas River Basin observed from 1956 to 2015,maan-kendall test and wavelet analysis are used to reveal the relationship between regional runoff and temperature.The results show that the runoff in the Manas River Basin shows an increasing trend with the linear increase of air temperature in the past 60 years,with a gradient of 0.0524×108 m3/a,which has passed reliability test of 0.05 and there was a certain time lag between the change of runoff and temperature.Some sudden changes occurred in 1993 and 1994,and the trend was rising.Wavelet analysis shows that runoff and temperature have a significant change period in 2~5 a,and meanwhile it presents a resonance variation on this scale. |
