摘要: 从文献中搜集整理1 397条古气温记录,建立全新世古气温记录数据集,该数据集多数时间段每百年的记录在10个以上。利用经剔除奇异值后的1 140条有效记录,采用单样本区域订正-多样本平均集成法,定量重建中国全新世百年分辨率气温集成序列。集成重建序列表明:全新世中国气温可以明显划分为三个阶段,早全新世(11.5~8.9 ka B.P.)为波动升温期;中全新世(8.9~4.0 ka B.P.)暖期的气温高出现代1℃上下,8~6.4 ka B.P.的暖期鼎盛期高出现代1.5℃左右;晚全新世(4.0 ka B.P.以来)为变冷期。

Abstract: About 1397 temperature records during the Holocene are collected to establish a temperature data set of the Holocene in China. 1140 of the 1397 records are available after eliminated the abnormal values statistically. There are more than 10 available records in most centuries during the Holocene in China. A synthesis reconstruction method, named the converted single sample from local to regional and averaged by the multiple samples, are designed to quantitatively reconstruct temperature change during the Holocene in China. The synthetically reconstructed Holocene temperature series in China ensures both the quantification and the higher temporal resolution continuously. According to the reconstructed temperature series, the Holocene temperature change in China could be obviously divided into three stages. The early Holocene (11.5-8.9 ka B.P.) was warming period when the temperature rose to near the present with fluctuation. The mid Holocene (8.9-4.0 ka B.P.) was a warmer period named the Holocene Megathermal, when the temperature was 1 ℃ higher than the present in average, with 1.5℃ higher than the present in maximum during 8.0–6.4 ka BP. The late Holocene (after 4.0 ka BP) was a cooling period.
