中文摘要	近年来，在全球变暖的背景下，生态脆弱的西北干旱区的气候变化受到人们重视。本文选取了西北干旱区21个代表站点19512000年逐月平均气温数据，分析气温季节变化特征和分区及其各分区各季节气候变化趋势。研究结果表明，近50a来西北干旱区气候变暖显著，其中冬季增暖幅度最大。按西北干旱区的年平均气温分为四个区。它们各季节气温变化趋势都有所不同，其增加幅度和数目最多的是柴达木盆地，随后是新疆北部和东部，新疆南部、河西走廊地区，新疆西部
英文摘要	In recent years, with the global warming of climate the brittle entironment in the northwest arid area of China received recognition of people. Based on the monthly mean temperature data of 21 stations during the period of 1951 to 2000, seasonal change character and regionalization of temperature and trends of climate change in the four seasons are analyzed. The results show that the climate obviously was becoming warm since recent 50 years in the northwest arid area of China, especially in the winter. The distribution of annual mean temperature is divided into four regions. Trends of climate change in the four seasons are different warming of climate. Chaidamu Basin is the greatest in four regions, followed in the northern and eastern Xinjiang, in the southern and eastern Xinjiang and Hexi passageway, in the western Xinjiang.
