| 摘 要： | 利用我国最北部的北极村气象站1963～2005年气温资料，通过计算气候倾向率和气候趋势系数，对该地区气候变化特点进行了分析。结果表明，43年来北极村气温有明显并稳定的上升趋势，年平均气温以每10年0．46℃幅度升高。各季及逐月平均气温都存在不同程度的变暖趋势，但是冬季升温最为剧烈，达每10年0．69℃，其中2月升温幅度为每10年1．02℃，为全年最大。秋季升温最弱，仅为每10年0．21℃。年平均最低气温（每10年0．59℃）和年极端最低气温（每10年0．74℃）比年平均最高气温（每10年0．37℃）和年极端最高气温（每10年0．27℃）升温幅度明显偏大。最低气温比最高气温对平均气温的年代际升温趋势贡献更为明显。

| Abstract: | On the basis of the records of air temperature from the northernmost meteorological station from 1963 to 2005, the characteristics of temperature change are analyzed by calculating climate trend coefficients and climate tendency. It is showed that temperature increased markedly and steadily in the last 43 years, with the annual mean temperature increased by 0. 46℃ per 10 years. Temperature in all months and in all seasons increased at different degrees, with the mean temperature in winter being the most sharply （0.69℃ per 10 years）, among which the increase in February was the greatest, being 1.02℃ per 10 years. The increase of mean air temperature in autumn was only 0. 2146℃ per 10 years, which was the smallest of the year. The variation tendencies of annual mean minimum temperature （0. 5946℃ per 10 years） and extreme minimum temperature （0. 7446℃ per 10 years） were greater than those of mean maximum temperature （0. 3746℃ per 10 years） and extreme maximum temperature （0. 2746℃ per 10 years）. Further analysis suggests that the interdecadal warming trend of minimum temperature is more evident than that of maximum temperature. |
