| 摘 要： | 根据南疆环塔里木盆地区1961—2010年以来资料完整的32个气象站点的资料，利用线性趋势函数分析了该地区近50年的冬季气温变化特征。结果表明：南疆环塔里木盆5个区域冬季年平均气温、平均最低气温、极端最低气温均呈增暖趋势，平均气温最高的年份集中出现在80年代末以后，冬季最暖年的出现具有统一性、大范围的特性暖温年多发生在80年代后，且90年代是50年中最暖的时期，冷年多发生在20世纪60年代、70年代；平均气温异常的年份为：1966年、1977为气温异常偏冷年，无异常偏暖年。

| Abstract: | According to the southern Tarim Basin region of 32 meteorological stations data during 1961-2010, using linear trend functions, the winter temperature variation characteristics in recent 50 year were analyzed. The results showed that ： the southern Tarim Basin5 Regional winter annual average temperature, the average minimum temperature, extreme minimum temperature showed a warming trend, the top average temperature was found in the late 1980s, and the most warm winter years came with the unity, a wide range of characteristics of warm years and the most warm period was found in the 1990s,with the cold years in the 1960s and 70s. The abnormal mean temperature years were found in 1966 and 1977 and there were no abnormal high temperature year. |
