Abstract: Using the temperature data in recent 40 years of 48 meteorological station, the paper analizes the stage, period and trend of temperature change, and compares the correlation of temperature change in Taklimakan area with around mountains and adjacent areas, and discusses the relationship between Euroasian circulation index and temperature change in the studied area. The results are as follows:(1) The annual and seasonal mean temperature sequences of this area have better reflected the warm-cold changes in the area.(2) The annual and seasonal temperature change have different warm-cold stages and change periods. The temperature change annual and in Winter have significant warming trend and the changing range in Winter is about three times as much as that of the annual. In recent 30 years, the annual temperature has increased 0.54℃ and the Winter temperature has increased 1.7℃.(3) The correlation of the temperature change in Taklimakan area with around mountains and adjacent area is better at Toyun station.(4) The correlation of the temperature change in Taklimakan area with adjacent areas is the best at Gansu province, second at Northern Xinjiang and the worst at Qinghai province. (5) There is significant negative correlation between annual temperature change in Taklimakan area and Euroasian annual mean longitudinal circulation index, and significant positive correlation between autumn temperature change and latitudinal circulation index from October to November.
