Synthetically Reconstructed Holocene Temperature Change in China

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.
