摘要： 利用岳普湖县气象站1971-2009年气温、降水、日照和风速等观测资料，分析岳普湖绿洲近39年来气候变化特征。结果显示：近39年来岳普湖绿洲气候趋于变暖，气温平均上升倾向率为0.21 ℃/10 a，年内除夏季气温呈降低趋势外，春、秋、冬季气温均呈上升态势。近39年来，岳普湖绿洲降水量总体呈减少趋势，降水量平均减少倾向率为-1.62 mm/10 a，年内春、秋两季降水量略呈增加趋势。日照总体呈增加趋势，平均增加倾向率为20.25 h /10 a。平均风速总体呈明显下降的趋势，平均下降倾向率为0.4 m/(s•10 a)。

Abstract: his paper analyzes the annual and seasonal changes of some metrological factors in the Yuepuhu Oasis in recent 39 years using the methods of regression analysis, trend analysis and 5year moving average analysis using the data of temperature, precipitation, sunshine duration and wind speed observed by the meteorological stations in the oasis during the period from 1971 to 2009. The results show that the annual temperature in the oasis was in an increase trend with an increase rate of 0.21 ℃/10 a in recent 39 years. The change of seasonal temperature was different, that is, the temperature was increased in winter, autumn and spring but decreased in summer. Precipitation in the oasis was in a decrease trend with a decrease rate of -1.62 mm/10 a. Seasonal precipitation was increased in autumn and spring but decreased in summer and winter. Annual sunshine duration in the oasis was in an increase trend with an increase rate of 20.25 h/10 a in recent 39 years. In recent 39 years, wind speed over the oasis was in a decrease trend with a decrease rate of 0.4 m/(s•10 a).

Key words: oasis, climate change, temperature, precipitation, sunshine duration, wind speed, Yuepuhu, Tarim River
