英文摘要	A stalagmite from Qixing Cave, Guizhou Province was dated with the TIMS U-series method and Its oxygen isotope composition was analyzed. On the basis of the ages and the variations of the delta O-18 of the stalagmite, the climate change of the last 7.7 ka has been reconstructed in this area: 7.7-5.8 ka, summer monsoon maximum period; 5.8-3.8 ka summer monsoon weakening period; 3.8-0.15 ka, weakened summer monsoon and high amplitude climate fluctuations period. We put forward that the increasing trend of delta O-18 of the stalagmite reflected not only the weakening of the summer monsoon, which was caused by the decreasing of solar radiation in the Northern Hemisphere, but also the possibly decreasing contribution of the southwest monsoon to the rainfall of this area. These results are consistent with the output of the numerical climate-model modeling. The high amplitude fluctuation of the delta O-18 may imply the quick shift of the contributions of different moisture sources to the precipitation in this area.
