| 摘 要： | 分析天山山区近40 a来年温度变化的基本特征,并与南疆、北疆进行比较,其结果是:(1)天山山区年平均温度在冷暖变化阶段上与北疆的相似性强于南疆。(2)新疆三大区域年平均温度的最主要空间分布特征均是同步变化,但同步性的程度北疆较好,南疆及天山山区较差;而空间分布的反向变化性,南疆及天山山区较好,北疆较差。(3)三大区域年平均温度的年代际变化趋势是不同的,但均以20世纪90年代为最暖。(4)近40 a的显著线性增温趋势以年平均最低温度及年平均温度表现得空间范围最广,年平均最高温度最差;年平均温度的长期增温率以北疆最大,天山山区和南疆较小;年平均最低温度的10 a增温率变化在0.34~0.37℃之间。(5)三大区域最佳升温趋势出现的时段比较一致,增温率以北疆为最大,天山山区和南疆相同。(6)北疆与南疆年平均温度分别在1960年和1978年发生了由低向高的突变。

| Abstract: | The basic features of annual temperature in Tianshan mountainous area for the recent 40 years are analyzed and compared with those in the Southern and Northern Xinjiang.The results are as follows:(1) The similarity of warm-cold stage of annual mean temperature between Tianshan mountainous area and the Northern Xinjiang is better than those in the Southern Xinjiang.(2) The synchronous change of spatial distribution of annual mean temperature is better in the Northern Xinjiang,and inferior in the Southern Xinjiang and in Tianshan mountainous area,but the reverse change of spatial distribution of annual mean temperature is better in the Southern Xinjiang and in Tianshan mountainous area,inferior in the Northern Xinjiang.(3) The decadal change trend of annual mean temperature is different in the three large regions of Xinjiang,but the temperature is the warmest in 1990s.(4) The spatial extent of significant linear warming trend for the recent 40 years is the widest for annual mean minimum temperature and annual mean temperature,the worst for annual mean maximum temperature.The long-term warming rate of annual mean temperature is the greatest in the Northern Xinjiang,smaller in Tianshan mountainous area and the Southern Xinjiang.The long-term warming rate of annual mean minimum temperature changes between 0.34~0.37℃ per ten years for the three large regions of Xinjiang.(5) The stages of optimum warming trends are similar for the three large regions,but warming rate is greatest for the Northern Xinjiang,and same for Tianshan mountain area as for the Southern Xinjiang.(6) The annual mean temperature for the Northern and Southern Xinjiang occurred abrupt changes from low to high in 1960 and 1978 respectively. |
