To study the paleoclimates changing in China, a high-resolution AMS radio-carbon dating of a loess profile at Weinan, Shaanxi Province, has been carried out and an age of 10,300 BP has been assigned to be the beginning of the HOLOCENE in the studied areas. In the south of China, a stalagmite of 1.2-m high taken from Panlong-dong cave, Guilin, Guangxi Province, has also been studied. The dating with micro-stratification sampling shows that the climate in HOLOCENE was generally damp and warm, but there was a short cola period during 10-11 Ka BP. The resolution of AMS carbon dating of stalagmite is 100 years for the warm and damp period and 500 years for the dry and cold period.
