摘要: 以中国全新世气温集成序列为资料,分析中国全新世气温变化特征,研究发现:全新世气温变化可以分为早全新世(11.5 ~ 8.8 kaBP)波动升温期、中全新世(8.8 ~ 4.2 kaBP)大暖期和晚全新世(4.2 kaBP 以来)转冷期3 个阶段。8.0 ~ 6.2 kaBP 是暖期盛期,气温较现代高1℃多。全新世期间发生多次冷暖事件,有11.0 kaBP、9.8 kaBP、9.2kaBP、8.9 kaBP、8.2 kaBP、6.2 kaBP、4.0 kaBP、2.8 kaBP、1.5 kaBP 和0.4 kaBP 等10 次冷事件,有8 次可以北大西洋相互对应;其中4.0 kaBP 和0.4 kaBP 是全新世最显著的冷事件;暖事件主要发生在8.6 kaBP、4.7 kaBP 和3.5 kaBP前后。全新世冷暖事件变化分别具有显著的1000a、700a的周期。

Abstract: Based on the researches on temperature change in China in the Holocene, the characteristics of temperature variability were displayed in this report. The temperature variation in the Holocene could be divided into three stages: ascending in the early Holocene with great fluctuations, Megathermal in the mid-Holocene, and descending in the late Holocene. The temperature in the warmest period of 8.0-6.2 kaBP was 1℃ higher than at present. Ten cold intervals which occurred in 11.0 kaBP, 9.8 kaBP, 9.2 kaBP, 8.9 kaBP, 8.2 kaBP, 6.2 kaBP, 4.0 kaBP, 2.8 kaBP, 1.5 kaBP and 0.4 kaBP were consistent with the eight cold events in the North Atlantic domain. It seems that the most significant cold-events appeared in 4.0 kaBP and 0.4 kaBP. Warm events occurred around 8.6 kaBP, 4.7 kaBP and 3.5 kaBP. The significant periodicities of temperature variation in the Holocene were 1000a and 700a.
