近年来,利用历史记载恢复我国历史时期气侯取得了可喜成果。然而使用单站长序列气象资料,进行气侯变化的研究却不多。早在60年代初,王绍武撰写了上海的气侯振动^[1]。毫无疑问,由于气象记录的连续,精确等特点,使气侯变化研究更加细致、可靠。因此单站长序列气象记录的分析,是气候变化研究中不可忽视的一个方面。

In this paper,the climatic fluctuations in Beijing during the past 100 years were analyzed.The climate is coldest between the end of 19th century and beginning of 20th century,1920’s and 1940’s are warmer,the last 30 years and colder than normal.The variation of precipitation is also analysed.The precipitation is more than normal from 1870’s to 1890’s.Since the begining of this century,the precipitation has been less than normal except 1950’s,but the summer rainfall is decrease obviously.The cyclic changes of the temperature and the precipitation were analyzed too in the paper. The relationships between climatic fluctuation of Beijing and solar activity, and the atmospheric circulation are discussed and the future climate of Beijing is inferred.
