摘　　要：柴达木盆地地处亚欧大陆腹地,是亚洲大陆干极核心,处于中纬西风带和东亚季风系统的交界带,对气候变化极为敏感。本文利用柴达木盆地五个气象站的资料,分析柴达木盆地气温变化,发现盆地气温显著上升,近50年来上升了2℃左右,远远大于全球上世纪升温0.6℃～0.7℃的水平。笔者推测柴达木盆地深居青藏高原内陆,青藏高原对全球气候变化有很高的敏感性,不仅迅速地响应全球变化的信号,而且对某些信号和趋势起着放大作用,还可能通过各种正反馈过程,对全球气候变化产生重大影响。<Abstrcat>As one of the aridest regions in Asia, Qaidam Basin is located in the center of Euroasia mainland. The region is very sensitive to global change owing to its location at the boundary between the middle latitude West wind system and the East Asia monsoon system. By Using the data of five weather stations in the Qaidam Basin in the past 50 years, we find that the temperature ascends about 2℃,which is much higher than that warming up 0.7℃ averagely in the world at the same time. Then we can conclude that Qaidam Basin is Located in the center of Tibetan Plateau and it is very sensitive to the global climatic change in Tibetan Plateau. It not only responses very quickly to climate change, but also can magnify climatic trends and tectonic signals by some processes of the positive feedback.
