中文摘要	利用线性趋势法、Mann-Kendall突变检测、滑动t检验和Sen斜率法等对中国青藏高寒区和西北干旱区1960-2015年气温时空变化特征进行了对比研究。结果表明,整体来看,1960-2015年西北干旱区的气温升高幅度[0. 32 ℃·(10a)~(-1)]高于青藏高寒区[0. 29 ℃·(10a)~(-1)]。1960-1997年西北干旱区的气温升高幅度[0. 22 ℃·(10a)~(-1)]高于青藏高寒区[0. 14 ℃·(10a)~(-1)],1998-2015年青藏高寒区的气温变化呈现升温趋势[0. 22 ℃·(10a)~(-1)],西北干旱区的气温变化呈现微弱的降温趋势[-0. 02 ℃·(10a)~(-1)]。青藏高寒区气温显著升高的区域是柴达木盆地和高原西南部地区,西北干旱区气温显著升高的区域是新疆北部以及内蒙古西部地区。青藏高寒区与西北干旱区的气温年代际变化规律均表现为20世纪60-80年代为相对低温时期,20世纪90年代至今为相对高温时期。突变分析表明青藏高寒区与西北干旱区气温开始出现增长的时间基本相同,西北干旱区气温突变的时间为1993年,青藏高寒区气温突变的时间为1994年。
英文摘要	The Qinghai-Tibetan Plateau region has long been regarded as the starting area and amplifier for our country and the global climate change,but many studies have shown that the magnitude of climate change in the northwest arid region of China cannot be ignored. Based on this,using the linear trend analysis,the sliding t test,the Mann-Kendall mutation detection and the Sen slope method,the characteristics of temperature on spatial distribution pattern and the multiple-time scale variability are analyzed by the monthly temperature data of 130 meteorological stations in the Qinghai-Tibetan Plateau region and northwest arid region of China during the 1960- 2015. The results show that: On the whole,the annual mean temperature change rate of northwest arid region of China[0. 32 ℃·(10a)~(-1)]was higher than Qinghai-Tibetan Plateau region[0. 29 ℃·(10a)~(-1)]during 1960-2015. However,the temperature variations of the Qinghai-Tibetan plateau region and the northwest arid region of China were distinct in different time periods. The annual mean temperature change rate of northwest arid region of China[0. 22 ℃·(10a)~(-1)]was far higher than Qinghai-Tibetan Plateau region[0. 14 ℃·(10a)~(-1)]during the time period of 1960-1997. At the same time,the temperature variation of Qinghai-Tibetan Plateau region had a significant rising trend,at a rate of 0. 22 ℃·(10a)~(-1) during 1998-2015,and the temperature variation of northwest arid region of China had a slight cooling trend,at a rate of -0. 02 ℃·(10a)~(-1) during 1998-2015. The regions with temperature rise significantly in the Qinghai-Tibetan Plateau region included the Qaidam basin and the southwestern region of the plateau. The regions with temperature rise significantly in northwest arid region of China included the northern region of Xinjiang and the western region of Inner Mongolia. The interdecadal variation of temperature in the Qinghai-Tibetan Plateau region and northwest arid region of China were characterized by the relatively cold phase during 1960s-1980s,and the relatively warm phase after 1990s. In addition,mutation analysis indicated that the temperature of Qinghai-Tibetan Plateau region and northwest arid region of China began to grow in the same time,but the temperature mutation time of northwest arid region of China was in 1993,and the temperature mutation time of Qinghai-Tibetan Plateau region was in 1994.
