摘要： 利用清代地方志中的异常初、终霜记载,根据器测时期华北初、终霜的早、晚与温度变化的关系,重建了1646-1910 年华北地区时间分辨率为5 年的冬半年温度距平序列,分析了期间的冷暖变化特征.结果表明：清代华北地区气候以寒冷为主要特征,冬半年温度平均较现代(1951-1980 年)约低0.55℃,最冷5 年(1656-1660 年)较现代约低1.42℃;清代华北地区冬半年气候存在“冷—暖—冷”的世纪波动,两个寒冷时段起讫时间分别为1646-1700 年(平均较现代约低0.77℃)和1781-1910 年(平均较现代约低0.58℃),1701-1780 年虽然相对较暖,但冬半年温度仍较现代略低(平均较现代约低0.36℃);从更高时间分辨率看,清代冷暖时段内同样存在较小的波动,清后期寒冷时段出现了两个“冷谷”.

Abstract: Based on the records of irregular first and last frost dates from the historical documents during the Qing Dynasty, the winter-half-year temperatures in northern China region are reconstructed at a five-year resolution by applying a conversion function to the historical records obtained from examining the correlation between the changes of first and last frost dates and the changes of instrument-measured regional mean temperatures in more recent years. The characteristics of temperature changes in that period are analyzed. The results indicate that: (1) the climate in northern China region in the Qing Dynasty can be characterized as cold. The mean winter- half-year temperature of that time period in the region is 0.55℃ lower than that of the present time (1951-1980), with a 1.42℃ difference in the coldest five years (1656-1660). (2) The centennial scale climate variations show a“cold-warm-cold”pattern. The two cold periods appear around 1646-1700 and 1781-1910, when the winter-half-year temperature in northern China region is about 0.77℃ and 0.58℃ lower than that of the present days respectively. During the period of 1701-1780, the climate is relatively warm, but the winter- half-year temperature is still lower than that of the present days (by 0.36℃ difference). (3) At a higher time resolution, relatively small temperature fluctuations are observed within each cold and warm time period, with two“cold troughs”during the late Qing Dynasty (1781-1910).
