| 摘 要： | 通过对新疆南疆盆地近45a气温变化特征分析，发现南疆盆地年平均气温在1989年开始发生暖突变。从1980年代末夜间温度开始异常升高，白天温度也随之升高，从而导致南疆盆地整体温度异常暖突变。最高、最低气温和气温日较差的变化具有明显的季节差异。在各个季节中，秋季和冬季温度的异常偏暖对年平均温度异常暖突变的贡献最大。在各种温度升高过程中，升温幅度最大的是最低气温，而最高气温的升温幅度远小于最低气温，从而日较差表现为减小的趋势。

| Abstract: | The temperature variation characteristics in Southern Xinjiang Basin in recent 45 years were analyzed and the results showed that there was a warm abrupt change of the annual average temperature in 1989. From 1980s end, along with the temperature during the night began to increase singularly and the same the day also increased, and the both caused the temperature warmed totally an abrupt change in Southern Xinjiang Basin. The change of maximum temperature, minimum temperature and diurnal temperature range all had distinct season differences. In the four seasons, the abnormity by warm in autumn and winter contributed most to the warm abrupt change of annual average temperature. In the above temperature increasing processes, the minimum temperature increased most, and the maximum temperature increased less extremely than the minimum temperature, so the diurnal temperature range tends to decrease. |
