| 摘 要： | 通过对历史文献资料的收集整理,重建了清代江苏省冬季逐年冷暖等级序列,并利用Morlet复小波变换分析方法对序列进行了多时间尺度特征的综合分析。结果表明:(1)整个清代江苏省冬季气候变化大致可分为2个冷时段(1644—1730年、1821—1900年)和1个暖时段(1731—1820年);(2)重建的冷暖等级序列存在多尺度下的周期变化特征,其中有较明显的周期变化尺度是38～42 a、18～20 a、13～15 a和8 a,38～42 a和8 a特征时间尺度的周期变化相对具有全域性,18～20 a尺度的周期变化在1690—1790年之间比较明显,13～15 a尺度的周期变化在1720年之前和1830年之后比较明显;(3)重建序列的第1主周期为42 a,第2、3、4主周期依次是20 a、 8 a和3 a;在42 a尺度下,清代江苏省冬季气候可划分为6个偏冷时段和6个偏暖时段。

| Abstract: | In this paper,the series of level of cold and warm in winterof Jiangsu Province during Qing Dynasty was reconstructed based on the historical documents. The integrated analysis of multiple timescale features of series was conducted using the Morlet complex wavelet transform method.The result indicated that: (1)The winter climate change of Jiangsu Province in the Qing Dynasty could be divided into two cold periods(1644-1730 AD,1821-1900 AD)and one warm period(1731-1820 AD);(2)The reconstructed series of level of cold and warm displayed a periodic variability in multiple scales,and the obvious ones were on the timescale of 38～42 a,18～20 a,13～15 a and 8 a,in which 8 a and 38～42 a were relatively dominant,and 18～20 a was more significant during 1690-1790 AD, while 13～15 a was more significant before 1720 AD and after 1830 AD;(3)The first to fourth primary periods of the reconstructed series were 42 a,20 a,8 a and 3 a respectively. In 42 a timescale, the climate of Jiangsu Province during Qing Dynasty could be divided into six cold periods and six warm periods. |
