CLIMATIC CHANGE DURING THE LONGSHAN PERIOD(5.0～4.0 kaBP)
The Longshan period(5.0～4.0 kaBP)is a key period for generation and development of the Chinese civilization.However,the climatic background of this period remains in dilemma.In this paper,based on historical documents,archaeological evidence,and high-resolution natural records reported during the past few decades,the climatic change during Longshan epoch was reconstructed following synthesis method recommended by IGBP.Our results indicate that the Longshang Epoch was not a uniform warm period as traditional researches suggested.It could be further divided into the early-middle Longshan Warm Period(5.0～4.5 kaBP),middle-late Longshan Cold Period(4.5～4.0 kaBP),and a pronounced cooling event by the end of the Longshan period(4.2～4.0 kaBP).The reconstructed climatic changes of the Longshan period are well correlated with the climatic records in the other parts of the world,indicating that it is at least a semi-sphere phenomenon.
