青藏高原地理位置特殊,在全球气候变化研究中有着特殊的意义.文章选取青藏高原典型城市——拉萨市进行气温变化特征分析.通过对拉萨市1980-2012年年平均气温、最低气温、最高气温及其年际与季节变化分析认为,拉萨市气温总体呈波动上升趋势,且以冬季上升最为显著.同时,多个指标表明1995年为气温变化的节点.此外,拉萨市气温指标与区域及全球气温变化良好对应,反映出全球气候变暖的同步性.

Tibet Plateau has a special significance in the research of global climate change because of its special geographical position. The typical city in the Tibet plateau-Lhasa as the study site, the characteristics of tem-perature changes was analyzed based on the mean temperature, minimum temperature, maximum temperature, annual and seasonal variation during 1980-2012. The results showed that there generally was increasing trend in creasing trend in temperature in Lhasa from year 1980 to 2012 and the most significant increase appeared in win-ter temperature and the key point of temperature rise appeared in year 1995 showed by various indicators. Fur-thermore, it could be a synchronous with global climate change, for instance, the temperature index of Lhasa has been showing a good correspondence with the regional and global temperature changes.
