摘　　要：利用Svalbard地区1901～2014年的月平均气温资料，对Svalbard地区的气候特征及趋势变化进行了分析。结果表明：年平均气温呈现上升趋势，增温率为0．27℃／10年；四季的平均气温也呈现上升趋势，春、冬季节升温明显，四季升温率（春夏秋冬）分别为0．38℃／10年，0．12℃／10年，0．25℃／10年和0．34℃／10年。此气温序列在1999年发生突变，升温速率明显加快。64年、27年、17年、8年和2年这5个时间尺度周期的波动控制着该地区整个时间域内气温序列的变化特征。Based on the average monthly temperature data observed in Svalbard during the period from 1901 to 2014, the article analyzes the climate change in Svalbard. The results indicate that the annual temperature shows an increasing tendency with an growthrate of 0.27℃/10a; the change of seasonal temperature also shows an increasing tendency, in whichtbe temperature of spring and winter increases obviouslyThe growth rate of four seasonal temperature is 0.38℃/10a, 0.12℃ ,0.25℃/10a,and 0.34℃/10a respectively. The temperature series suddenly changed in 1999 and the heating rate speeded up obviously. The change features of temperature series during the whole time domain in Svalbard is dominated by the fluctuation of five time scales of 64 years,27 years,17 years,8 yearsand 2 years.
