摘要
用西北五省（区）１３５个代表站１９６０－１９９０年的年、季平均气温资料，进行模糊聚类分区。在０．００１信度水平下，年平均气温可以分为四个大区，分别是：新疆北部区、西北主区、柴达木盆地和长江黄河上游区。由此，建立了四个区的全年和冬、夏季气温代表序列，并对近几十年的西北五省（区）气温变化进行了初步分析．
Based on the annual and seasonal mean temperaturedata of 135 stations over thelive prOvinces in NorthwestChina during the period of 1960 to 1990,the distribution ofannual mean temperature is divided into four regions with the significance level of 0. 001by the fuzzy classification lnethod.They are the north part of XingJiang;the most partsof the area in Northwest China;the Qaidam basinland the upper streams of Yangtzeand Yellow Rivers,respectively,Furthermore,the temperature sequences of the year,winter and summer for the four areas are set up, and the variation of temperatures forthe recent several decades in Northwest China is analysed.
