| 摘要 | Here we present a decadal-resolved hydroclimate record covering the past 11 thousand years based on
d18O data of three stalagmites from Klang Cave (TK) on the Thai-Malay Peninsula, southern Thailand. The
d18O values indicate wetter conditions/more rainfall during the early Holocene from 11 to 7 thousand
years before present (kyr BP). A large increase of 2‰ in d18O is observed from 7.0 to 6.0 kyr BP, indicating
a millennial drying period followed by drought conditions between 6.0 and 5.2 kyr BP. After a long hiatus
(5.2e2.7 kyr BP), d18O data show a millennium-long trend toward dry conditions. An abrupt positive
change of 0.8e1.0‰in d18O is noticed between 8.29 and 8.17 kyr BP, reflecting the 8.2-ka event; however,
the amplitude of the d18O shift is much smaller comparing to that of the event of 6.0e5.2 kyr BP. On
orbital time-scales, the TK record agrees with insolation-dominated speleothem records in the Asian-
Australian monsoon realm. Noticeable inconsistencies among records in the Southeast Asia region (between
8 fic region, based on stalagmite d18O records from
Klang Cave (8 Indo-
Pacific region, controlled by the interhemispheric extratropical insolation gradient, may strongly
correlate with the El Ni~no-Southern Oscillation (ENSO) activities in the Holocene. |
