摘 要：Tan M.2007.Climatic differences and similarities between Indian and East Asian Monsoon regions of China over the last millennium: a perspective based mainly on stalagmite records.International Journal of Speleology,36(2),75-81 Bologna(Italy).ISSN 0392- 6672 Cave sediments,especially stalagmites,have been providing absolute dated climate records that can extend from the present to over 500,000 years ago.Based on the reconstructed temperature time series,a comprehensive overview of the climatic differences and similarities between the Indian and the East Asian Monsoon regions of China over the last millennium is presented.Evidence from accurately dated and high-resolution records including stalagmites,ice cores and tree rings show that there was aMedieval Warm Period(around 1000 to 1400 AD) in north and east China where climate is dominated by the East Asian monsoon;whilst no such interval is evident in the records including stalagmites and ice cores from southwest China where climate is dominated by the Indian monsoon.However,both regions underwent a significant cooling during the Little Ice Age(around the mid 1500s to the 1800s). The result achieved here may allow a possibility of distinguishing the boundary between Indian monsoon and East Asian monsoon regions over the last millennium with increase of climate records,especially stalagmites that are mostly suitable for accurate U/Th dating and/or lamina counting.
