In order to study the characteristics of climate change in Mu Us Sandy Land and provide references for regional desertification prevention and disaster warning, based on the monthly temperature and precipitation data from 1960 to 2018 of 10 meteorological stations in Mu Us Sandy Land and its surrounding areas, the climate variation characteristics, the future trend and main influencing factors of climate change in Mu Us Sandy Land were explored by the method of linear tendency estimate, Anusplin spatial interpolation, Mann-Kendall mutation test, Morlet wavelet analysis, R/S analysis and Pearson correlation analysis. The results indicated that:(1)the annual average temperature of Mu Us Sandy Land showed a significant upward trend in recent 59 years, with an annual warming rate of 0.35℃/decade; the abrupt time point of annual average temperature was about in 1996 and it fluctuated in 4-year cycle; in addition, the increase rate of the temperature accelerated with the increase of altitude;(2)in recent 59 years, the change rate of annual precipitation in Mu Us Sandy Land was 2.88 mm/decade, and the summer precipitation increased rapidly; however, these variation trends were not significant and there were no obvious abrupt time points of precipitation and significant oscillation periods;(3)in the future, both the average temperature of annual and each season will have a tendency to continuously increase, so does the autumn precipitation. In general, the climate in Mu Us Sandy Land is warming and getting wet. And the El Niño-Southern Oscillation(ENSO)events had a significant effect on the average temperature of winter in Mu Us Sandy Land, while the Arctic Oscillation(AO)and the North Atlantic Oscillation(NAO)had a relatively remarkable effect on the precipitation of winter and summer in Mu Us Sandy Land.
