Abstract: The oasis in the arid zone affects significantly on the local oasis climate. This paper used temperature，precipitation and relative humidity monthly observation records of Cele Weather Stations and Andier Weather Stations at Hotan Prefecture from 1960-2011，further analyzed climate change in southern Xinjiang oasis features，and lookedinto different oases linkages between climate change. The research results on the oases located in the southern margin of Taklimakan Desert show that in the past 52 years，the climatic change trends of Cele oasis and Andier oasis are similar in general，such as the temperature in the two oases has a significant upward trend，among which the minimum temperature has tended to increase significantly，but the maximum temperature has not significantly changed，the annual temperature range is reducing；the annual precipitation is increasing，and there exist precipitation anomalies year，precipitation increase trend of Andier Oasis is significant，and appears precipitation mutation；the annual humidity is decreasing；the tendency rate of annual precipitation at the oases in the south margin of Tarim Basin is decreasing gradually from the west to the east. The “Cold Island Effect” of oasis is related to oasis area，the tendency rate of temperature of oasis with larger area is smaller.

Key words: oasis, climate change, southern margin of Taklimakan Desert
