Description :
The AA. report a preliminary study on a Holocene stalagmite from Shihua Cave in Southwest Beijing. The result shows that the thickness of annual growth layers which is defined by annual deposit hiatuses preserve changes with precipitation. In light with the thickness of annual layers the AA. reconstruct the climatic variation history of the last 2300 years in Beijing area. The oxygen isotopic composition preserves monsoon variations, which is matched in interpretation of the change in layer thickness. Carbon isotopic composition reflects the changes in vegetation activity likewise the anthropogenic activity.
