中文摘要	干旱区的绿洲明显影响着绿洲局地气候。研究表明：近52a来，策勒绿洲和安迪尔绿洲气候变化的总体趋势基本一致，两处绿洲的气温均呈现上升趋势，其中最低气温上升明显，但最高气温没有显著变化，气温年较差减少；降水增加，并且均存在降水异常年份，其中安迪尔绿洲降水增加趋势显著，并且存在突变；两处绿洲总体相对湿度呈现轻微下降趋势，但逐年变化幅度不大。塔里木盆地南缘绿洲降水存在从西向东倾向率逐渐增加的趋势；绿洲的冷岛效应与绿洲面积有关，面积较大的绿洲气温倾向率较小。
英文摘要	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.
