摘要
根据曲阜市 196 5～ 1999年的气温资料 ,分析了曲阜市近 40年来的气温变化 .结果表明 :(1)近40年来曲阜市的年平均气温、平均最高气温、平均最低气温均表现出明显的上升趋势 ,气温倾向率分别为 0 .2 17℃ / 10a、0 .0 94℃ / 10a和 0 .45 9℃ / 10a ,其中平均最低气温的上升趋势最明显 .(2 )不同季节气温的变化趋势不同 ,冬季气温上升趋势最显著 ,平均气温、平均最高气温和平均最低气温的倾向率分别为 0 .743℃ /10a、0 .484℃ / 10a和 1.0 47℃ / 10a .(3)按近 40年的冷暖波动情况 ,将气温变化分为 3个阶段 ,即 6 0年代偏暖时期、70～ 80年代的偏冷时期和 90年代的偏暖时期 .
According to the data of temperatures from 1965 to 2000 in Qufu, the change of the mean temperatures, the mean maximum temperatures and the mean minimum temperatures were calculated and analysed in detail. The results are as follows: (1) annually, the mean temperatures, the mean maximum temperatures and the mean minimum temperatures are increasing, among which the increasing rate of the mean minimum temperatures is the biggest. (2) seasonally, the mean temperatures are increasing in spring, autumn and winter, the increasing rate is the biggest in winter; the mean minimum temperatures are increasing in all seasons, especially in winter; the mean maximum temperatures are increasing in autumn, the increasing rate of winter is the biggest. (3) the climate of Qufu for 40 years might be divided into 3 stages, the 1960's and 1990's are warm periods, the 1970's and 1980's are cold period.
