摘要
Monitoring and sampling of soil waters and cave drip waters during the periods from April 2003 to May 2004 were performed monthly at Qixing Cave, Duyun, Guizhou Province, Southwest China, in order to understand the effects of hydrogeochemisty on δ13CDIC of cave drip waters and their implications for interpreting the potential paleoenvironmental signal preserved in speleothems. The results show that there exists remarkable difference(≤6. 9‰)among δ13CDIC of cave drip waters at 9 sampling sites synchronously. Therefore, the accurate interpretation of δ13C recorded in speleothems can not be guaranteed if not considering the effects of the above mentioned hydrogeochemical processes.
