摘要
By dating ages of TIMS-U series and analyzing carbon and oxygen isotope and content of organic carbon in XR1 stalagmite from Xianren Cave in Xundian, Yunnan Province, this paper reconstructs monsoon climate change pattern during the Middle Holocene in Xundian. At last, on the basis of δ18O record and summer solar radiation at 33°N latitude, the driven factors of climate change in Xundian, Yunnan Province dring the Middle Holocene is analyzed. The result show the climatic changing trend in Xundian,Yunnan Province was controlled by summer solar radiation at 33°N latitude and may affected by volcanic activity during the Middle Holocene.
