In order to study the periodicity variation and trend prediction of temperature in Yaoba Oasis, based on the temperature data from 1955 to 2012 of Barunbieli weather station, linear trend method, Mann-Kendall test and wavelet analysis were used to analyze the trend, mutation point and periodicity. The results showed that the temperature had a significantly warming trend nearly 60 years in Yaoba Oasis while there was one mutation point at 1986. The temperature had short periodicities of 4 and 9 years, so it would increase from 2016 to 2020 that it was closely related to the background of the global climate warming trend. This paper not only provided a scientific basis of the future short-term temperature change for Yaoba Oasis but also provided a theoretical reference for the local agricultural production.
