Background, aim, and scope Yulin is located in the middle of the patterns in northern China, with a fragile ecological environment, is a sensitive area of global change responses. Materials and methods Based on meteorological stations in Yulin, 1951 2012 calendar year daily air temperature data, using linear regression analysis, moving average, wavelet analysis, and Mann-Kendall to analyze the characteristics of temperature changes in the region and mutation phenomena. Results The results show that the average temperature was increasing during 1951 2012, and the linear tendency rate was 0.27℃·(10a)~(-1). The annual average temperature has revealed the 3 to 7 and 25 to 28 quasi-periodic variation in the past 60 years, and the abrupt change has occurred in 1994. In temperature, the four seasons in linear trend rate were 0.26℃ ·(10a)~(-1), 0.07℃·(10a)~(-1), 0.21℃·(10a)~(-1), 0.56℃·(10a)~(-1). Spring, autumn, winter mean temperature and annual average temperature, warming trend is obvious, but relatively late in summer. Discussion Due to the geographical position of Yulin, prone to drought, fragile ecological environment, in addition to the temperature affected by the atmospheric circulation, El Nino and La Nina and other natural factors, but also the existence of manmade factors. Conclusions In general, from the beginning of twenty-first century, a downward trend in the basis of temperature in the city of Yulin will maintain the high temperature, The annual average temperature has revealed the 3 to 7 and 25 to 28 quasi-periodic variation, and the abrupt change has occurred in 1994. The four seasons are in increasing temperature, the most obvious increase in winter temperature, increase of 2.8℃ . Recommendations and perspectives Analysis on the characteristics of temperature variation in Yulin, not only provides a theoretical basis for the development of agriculture and animal husbandry industry in the region, provide a theoretical basis for understanding the Maowusu Desert and its surrounding areas of environmental change, desertification and climate change science. In order to have a deep understanding of the forecast of the future temperature change and the response of the ecological environment in the region.
